Introduction The Hotwire® 8300 Endpoint is a feature-rich, intelligent integrated access device (IAD) that manages voice and data applications in an ATM network. The 8300 Endpoint terminates a standards-based Symmetric High-Bit Rate Digital Subscriber Line (SHDSL) that originates from a Digital Subscriber Line Access Multiplexer (DSLAM) and provides interfaces for the end user’s communications equipment. The 8300 Endpoint is a service-aware IAD with the following hardware: SHDSL network interface Constant Bit Rate (CBR) port configurable as T1 or E1 Serial port software-configurable for V.35, V.36, X.21, RS-232, RS-449, or EIA-530 10/100Base-T Ethernet port Asynchronous Supervisory port Five tri-color status LEDs Front panel reset and factory configuration buttons The Circuit Emulation Service (CES) support provides for the encapsulation of TDM traffic from end-user equipment into ATM cells for transport across the WAN to the DSLAM and on to the ATM network. This allows for the continued use of existing TDM equipment at the customer premises while the ATM network continues to grow and move further out to the edge. This unit supports CES over the CBR port and the Serial port. A router or bridge using PPP/HDLC protocols connects to the 8300 Endpoint’s Serial port. The unit encapsulates the PPP data into ATM cells using Internet Engineering Task Force (IETF) RFC 1483. Any router/bridge supporting PPP over ATM (PPPoA) RFC 1483 encapsulation can be used at the other end of this ATM connection. The IP Gateway feature enables IP packet routing throughout a LAN/WAN network architecture using static routing configuration or dynamic routing protocols RIP (Routing Information Protocol) 1 and RIP 2, or OSPF (Open Shortest Path First), Dynamic Host Communications Protocol (DHCP), and Network Address Translation (NAT).

1-2 April 2003 8300-A2-GB20-00 RIP 1 and RIP 2 allow routers to exchange routing information. The 8300 Endpoint then uses this information exchange to build routing tables for IP Packet routes. After building the routing tables, the unit periodically broadcasts the contents to neighboring routers so your network can choose the most efficient routes available. OSPF uses link-state routing algorithms to calculate routes based on the number of routers, transmission speeds, delays, and route costs. Using the OSPF protocol, the 8300 Endpoint works with other routers in your telecommunications fabric to dynamically change routes on the fly to make use of the most efficient and cost-effective transit across your network. Bridging separate LANs together is another option for the IP traffic. Using the IEEE Standard 802.1D Transparent Bridging specification, the 8300 Endpoint can simplify your network architecture by allowing you to bridge separate LANs across a WAN so they operate as a single LAN. Because IP Gateway enables the 8300 Endpoint to route IP traffic either statically or dynamically or to bridge IP traffic across your LAN/WAN architecture, your need for costly routers is substantially reduced. This one-stop solution can help you meet the requirements of your many different applications. DHCP uses a server-client architecture to assign IP Addresses to PCs and workstations on the LAN. The DHCP server dynamically assigns these IP Addresses, which can be either temporary or permanent, to each PC or workstation (DHCP client). These IP Addresses are housed on the DHCP server. The flexibility to reassign IP Addresses saves the end user money by eliminating the need for a single IP Address for each piece of equipment on the LAN. NAT enables an enterprise to set up two sets of IP Addresses: one set for internal network use (or LAN traffic) and one set for external use (or Internet traffic). This can provide a layer of security for a company by eliminating outside access to internal IP Addresses from the Internet. The 8300 Endpoint gives service providers and enterprise customers the capability to monitor end-to-end network performance (with support of up to 16 virtual channels); isolate performance problems to the LAN, local loop, or ATM network; determine appropriate bandwidth needs; and monitor network trends to aid in future capacity planning. All of the 8300 Endpoint’s installation, performance configuration, traffic monitoring, alarm reporting, and diagnostic capabilities can be configured through the unit’s embedded web server interface using Microsoft® Internet Explorer™. The web server interface can be accessed locally through the Ethernet port or the Supervisory port, or remotely through the Network port. Especially advantageous is the unit’s advanced monitoring and control capability that gives network administrators the ability to plan future capacity requirements. The unit’s built-in Service Aware technology lets network managers maximize available WAN bandwidth and verify SLAs. This management platform lets the end user see network activity and problems on any permanent virtual circuit (PVC), access line, or physical circuit.

8300-A2-GB20-00 April 2003 1-3 Features of the 8300 Endpoint Performance Historically, WAN access devices have tended to perform well as single-function devices such as CSU/DSUs, but have not been optimized to address higher-level traffic issues such as service levels and integration. The 8300 Endpoint’s architecture and web-based user interface work together to address all access issues such as services and applications, rather than as circuits and protocols, for exceptional WAN management performance. The 8300 Endpoint also allows firmware to be upgraded via the web from a standard browser, with password control if desired. SNMP Management With integrated SNMP in-band management, enterprise managers can now manage 8300 Endpoints and their integral CSU/DSUs as a single unit. With only one LAN segment in the network, the 8300 Endpoint can be managed by SNMP. By downloading all configuration parameters from the central site, no interaction is required at remote sites to establish connectivity. The unit allows any port to be configured for any of its available service technologies through simple software configuration. Network managers can now fine tune the enterprise network for the lowest cost and highest performance. Intelligent WAN Access Architecture The 8300 Endpoint’s WAN access architecture is built around a PowerPC™ processor with 50 MIPS of processing power and 16 Mbytes of onboard memory, and works with non-proprietary network management solutions via SNMP. An embedded web server supplies a simple-to-use interface for configuration and statistics collection, with a service table for mapping services to ports and a user table for monitoring and controlling traffic. Overview and Advantages The 8300 Endpoint is an innovative, highly intelligent, software-based WAN access device optimized for ATM over G.shdsl access. This unit provides network managers with all the tools necessary to monitor and troubleshoot voice, data, and network transmission systems. The ability to use the 8300 Endpoint as an IP Gateway greatly increases its flexibility, while reducing networking costs. In addition, the 8300 Endpoint is a valuable tool for the following: Measuring and reporting performance Managing network resources to ensure optimum performance Analyzing trends to aid in network planning 8300 Endpoint advantages include the following: Uses the international standard G.shdsl.

1-8 April 2003 8300-A2-GB20-00 Rear Panel Connections The rear panel of the 8300 Endpoint has five connectors. From left to right, these are as follows: POWER, SUPERVISORY PORT, 10/100 ETHERNET, SERIAL, CBR, and NETWORK as shown in Figure 1-2. below. Figure 1-2. 8300 Endpoint Rear Panel Power Port The POWER port on the 8300 Endpoint is a standard, grounded, three-prong connector. To apply power to the unit, simply plug the supplied power cord into the unit’s POWER port and then connect the wall plug to an appropriate electrical outlet. The unit has no power switch. When power is applied to any 8300 Endpoint, the front panel indicators flash for approximately 10 to 15 seconds as the unit initializes. The green POWER LED on the front panel will remain illuminated as long as the unit receives power. This LED turns amber when the unit is in test mode. CAUTION: Always connect the power cord to a grounded electrical outlet. NOTICE: Per UL 1950 and CSA 60950 Clause 1.7.2, if the power supply cord is intended to serve as a disconnect device, an easily accessible socket must be installed near the equipment. Power Failure If the indicator does not illuminate, check the power connections and the primary circuit breaker. The 8300 Endpoints provide nonvolatile memory retention of the unit configuration in case of a power failure. The unit will automatically restore normal service following a power loss and will retain pre-existing time and date information.

8300-A2-GB20-00 April 2003 1-9 Supervisory Port The SUPERVISORY port is a DB-9 female DCE connector configured for 8 bits, no parity, and 1 stop bit. Bit rates are configured through the web server interface. (See Unit Access Details on page 2-24.) The Supervisory port speed can be set to 1200, 2400, 4800, 9600, 19200, 38400, 57600, or 115200 bps. The initial default rate of the Supervisory port is 19200 bps. On power-up, the Supervisory port sends out diagnostic messages at the bit rate of 115.2 kbps until the Supervisory service acquires the Supervisory port, after which the port speed is changed to the setting in the Supervisory interface screen. NOTICE: For information on pinout assignments for this connector, refer to Supervisory Port Pin Assignments in Appendix A, Specifications. See Standard Equipment in Appendix A, Specifications, for information on cables for this connector. 10/100 Ethernet Port The 8300 Endpoint provides a single 10/100 ETHERNET interface port for IP Gateway, SNMP, and web browser access. This interface is an eight-pin modular jack that complies with standard twisted-pair, 10/100Base-T requirements. The 10/100Base-T cable is supplied by the end user. Refer to Ethernet Connection Pin Assignments in Appendix A, Specifications for pin assignments and cable descriptions. Ethernet LED Indicators There are two unlabeled indicator LEDs on either side of the 10/100 Ethernet jack.

The 8300 Endpoint has an innovative, embedded web-based user interface for remote configuration and real-time reporting via Microsoft Internet Explorer 5.0 or higher. Access to the web server interface and how the interface is used to configure the 8300 Endpoint are described in detail below. NOTICE: Use of Microsoft’s Internet Explorer 5.0 or higher is recommended. If you use other Internet browsers to access the web server interface, some screen elements will not be displayed as described in this manual. NOTICE: The material presented in this chapter follows the order listed in the navigation bar on the left side of the Web Server interface screen. However, because the parameters you specify in the Service Table attach protocols to interfaces, you must configure the Service Table first. (See Services on page 2-25.) You will not be able to allocate channels (see Channel Table Details Screen on page 2-38) until the Service Table has been configured. Configuration through the VT100 interface is covered in Chapter 3, VT100 Interface.

2-2 April 2003 8300-A2-GB20-00 Web Server Access You can access the Web Server interface by connecting to its IP address. This connection can be directly through the 10/100 Ethernet port, in-band via PPP over any port, or in-band via encapsulated IP traffic on the ATM WAN circuit. NOTICE: Any changes to the unit’s configuration MUST be followed by a Submit if there is a Submit button on the menu. If you change the Service Table, you must perform a Save and Restart. To access the Web Server interface, type the unit’s IP address in the browser’s Address (or Location) field and press the Enter key. Layout of Interface Screens When you first access the Web Server interface, your browser will display a screen that is divided into three frames. The upper frame forms a border across the top of the screen; it identifies the unit in service and displays the hardware and software revision and serial numbers under which the unit is operating. The far right corner of the upper frame displays whether or not a Save and Restart is necessary when parameters are changed on the currently displayed screen. The area beneath the upper frame is divided into two side-by-side frames. The frame on the left side of this area depicts a hierarchical tree structure used to navigate through the various interface screens. Each branch on the tree guides you to more specific upper-level information about the unit and its configuration. Note that the Interfaces, Applications, and Utilities branches do not link to a page; these branches simply provide structure for navigation. The frame on the right side of the screen displays the actual configuration screen. The screen images throughout this chapter show only the configuration portion of the screen, except in the case of the Unit screen, which shows the left and right frames. The Unit screen represents the top of the navigation tree.

8300-A2-GB20-00 April 2003 2-3 Unit Screen The first screen displayed by the unit’s Web Server interface is the Unit screen (Figure 2-1). This screen lets you view and set specific information about the unit in service. Figure 2-1. Unit Screen The Unit screen displays the following fields: Field Function Object ID Display-only field used to point an SNMP agent to this ID. Up Time Displays the amount of time the unit has been up and running. Contact Stores the name of a point-of-contact for system failure. Name Read/write field that holds the unit’s name. Location Read/write field that holds the unit's location. FrameStart ID Not used for ATM. Read/write field that holds the unit's ID that uniquely identifies the unit and is used in the FrameStart applications. Blank Fields Read/write fields for user-specific labels and values. Information resides in non-volatile memory. Time Read/write field that holds the unit's internal time setting in standard 24-hour HH:MM:SS format. Date Read/write field that holds the unit's internal date setting in standard MM/DD/YY format.

2-4 April 2003 8300-A2-GB20-00 The Unit screen provides the following user-activated buttons: Maintenance Reset Use this button to perform a Maintenance Reset. All configurations will be lost and the unit will be set back to an initial factory configuration. There are five options for a Maintenance Reset as shown in the table below. * Factory default configuration All the factory configurations set up an ATM service on the Network port with one configured virtual channel (VPI=0, VCI=32). Management data received on this channel (either WEB or SNMP) will be processed at the unit if it is encapsulated using RFC 1483 and directed to the unit’s IP address. (A Maintenance Reset will not change the unit’s IP address.) The Serial HDLC configuration and the T1 CBR configuration will also accept PPPoA encapsulated data and deliver it to the Serial port. The T1 CBR, E1 CBR, and Serial CES configurations set up a CES service between the Network port and the T1/E1 CBR port or the Serial port using VPI=0, VCI=33. The T1 CBR configuration sets up the CBR port to run T1 and has 24 channels delivered to the CES service. The E1 configuration sets up the CBR port to run E1 and has 31 channels delivered to the CES service. The Serial CES configuration sets up the CBR port to run E1, but allocates Channels 1−31 to the Serial port. Clicking the Maintenance Reset button will display a selection screen with a drop-down list of the available configurations as shown in Figure 2-2. Button Function Submit Sets any values that have been changed. Use the top Submit button to set unit parameters changed in the upper section of the screen, and the lower Submit button to set the real-time clock.

2-16 April 2003 8300-A2-GB20-00 E1 CRC4 Mode Provides line integrity detection to determine if bit errors are present on the line. Values: Disable, Enable Default: Disable Error Status and Alarm Thresholds Table The unit can be programmed to generate an alarm condition based on a specific level of performance degradation. The CBR screen presents a table that provides current error status and alarm threshold information. Acceptable alarm thresholds are set for periods of 15 minutes (900 seconds) and sampled every second. The error types listed in the following paragraphs can be preset to a value between 0 and 900 seconds. Setting a field to 0 (zero) disables the alarm on that statistic. To effectively disable alarm reporting, set all fields to 0 (zero). The 15-minute time frame is not based on the TR 54016 or T1.403 interval boundaries, but is a time window based on the accumulated counts over the previous fifteen 1-minute intervals. In all cases, if the number of actual network errored seconds in the previous 15 minutes reaches the preset threshold for the specified error type, an alarm condition is declared. The four columns of the status table are as follows: Status: Displays the current status of the CBR port. Alarm: Displays the alarm value of the network port. The unit declares an alarm as soon as the count exceeds the threshold set. Count: Displays the number of events or occurrences of this statistic that have been detected. Threshold: Displays a read/write field that can be set to a desirable threshold. The table provides error status and alarm threshold information for the following error parameters: ES Sets the Errored Seconds (ES) threshold. An ES is a 1-second period in which at least one logic error occurred. The default value is 45 seconds. SES Sets the Severely Errored Seconds (SES) threshold. An SES is a 1-second period in which at least 320 CRC errors or one Out-of-Frame (OOF) error occurred. The default value is 5 seconds. LOSS Sets the Loss of Signal Seconds (LOSS) threshold. A LOSS is 1-second period in which the T1/E1 received signal is interrupted. The default value is 5 seconds. UAS Sets the Unavailable Seconds (UAS) threshold. A UAS is a 1-second period in which consecutive severely errored seconds cause an unavailable state. The default is 0 seconds (Disabled). CSS Sets the Controlled Slip Seconds (CSS) threshold. The default is 0 seconds (Disabled).

8300-A2-GB20-00 April 2003 2-17 BPVS Sets the Bipolar Violation Errored Seconds (BPVS) threshold. A BPVS is a 1-second period in which at least one bipolar violation occurred. The default is 0 seconds (Disabled). OOFS Sets the Out of Frame Seconds (OOFS) threshold. An OOFS is a 1-second period in which a frame sync loss occurred. The default value is 5 seconds. AISS Sets the Alarm Indication Signal Seconds (AISS) threshold. An AIS is a 1-second period when unframed all ones are received. The default is 0 seconds (Disabled). RAS Sets the Remote Alarm Seconds (RAS) threshold. An RAS is generated by the terminal equipment when an improper signal is received from the facility (or upon receipt of unframed all ones). The default is 0 seconds (Disabled). Reset Timer Sets the Reset Timer threshold. This field is the contiguous number of seconds that an alarm parameter must be clear before the alarm is reset. Applicable values range from 000 through 900. A value of 000 means the alarm will never be reset. The CBR screens provide the user-activated buttons described below. CAUTION: Performance data will be lost upon power cycle or after performing a Maintenance Reset/Restart. Figure 2-14. Performance/Summary Screen Button Function Submit Sets any values that have been changed. Clear Alarms Resets the alarm conditions and counts to zero. Performance Displays a Performance/Summary screen that shows a current count of the number of error events that have occurred over the past 24 hours and the past 30 days.

2-18 April 2003 8300-A2-GB20-00 In addition to the error parameters found in the Error Status and Alarm Thresholds Table on page 2-16, the following error parameters are included on the Performance/Summary table: BES Sets the Bursty Error Seconds (BES) threshold. A BES is a 1-second period during which at least more than one but fewer than 320 CRC6 errors occurred. LOFC The Loss of Frame Count (LOFC) represents the number of time a loss of frame is declared. A loss of frame is declared after 2.5 seconds of continuous loss of signal or OOF. CRCES Sets the Cyclic Redundancy Check Errored Seconds (CRCES) threshold. A CRC is a method of confirming the integrity of received data. Beneath the Performance/Summary table are two buttons: Performance 24 Hour and Performance 30 Day. Clicking either of these buttons will display a detailed summary of the error events that have occurred during each 15-minute interval of the past 24 hours (Figure 2-15) or during each interval (day) of the past 30 days (Figure 2-16).

8300-A2-GB20-00 April 2003 2-19 Serial The Serial screen (Figure 2-17) lets you view and make changes to the unit’s Serial interface configuration as described in the paragraphs below. To make changes to any Serial port parameter, simply set the parameter to the desired selection and press the Submit button. Figure 2-17. Serial Screen Type Selects the type of interface (based on its electrical signal characteristics) used by the equipment connected to the Serial port. Values: V.35, V.36, RS-232, EIA-530, and X-21 Default: V.35 NOTICE: V.35 requires the use of an optional cable. Refer to Connector Pin Assignments in Appendix A, Specifications, for ordering information. Mode By default, the Serial port serves as a DCE port. However, the Serial port can serve as a DTE port. If the Serial port connects to a DTE device (such as a FRAD or a router), the Mode parameter must be set to DCE. If this port connects to a DCE device (such as a DSU/CSU), this parameter must be set to DTE. Values: DCE, DTE Default: DCE NOTICE: DTE mode requires the use of an optional DTE cable. Refer to Connector Pin Assignments in Appendix A, Specifications, for ordering information. NOTICE: When you configure the Serial port for CES, you must set the port mode to DCE.

2-20 April 2003 8300-A2-GB20-00 Packet Rate Packet Rate must be configured to the desired port speed (in bits per second). Values: 64−2304 kbps Default: 2048 kbps Bundling Selects whether the DTE channel assignment is made as a Contiguous group or as Alternate channels. Selecting Alternate ensures ones density. Because the unit allows individual channels to be configured for a service, a value of Arbitrary will be returned for this parameter if the current channel allocation is not contiguous or Alternate. The Arbitrary value can only be supplied by the unit − it cannot be set by the user. Values:Contiguous, Alternate, Arbitrary Default:Contiguous NOTICE: Because Alternate Bundling assigns every other channel, only half the channels are available. Start Channel Selects the starting channel in the 24-channel DS1 bit stream. Starting with the specified channel, the unit automatically assigns the channels that follow. Values:1−24 for T1; 0−31 for E1 Default:1 Number of Channels Specifies the number of channels to be assigned to the DTE. Values:0−24 for T1; 0−32 for E1 Default:24 Channel Rate Format Selects the port’s operating mode. Values: Sync, Async Default: Sync Tx Clock Selects the clock the unit uses to sample the data transmitted from the DTE. When set to Internal, the data is sampled directly with the transmit data clock that is also supplied to the DTE as Transmit Clock. The External option uses the external clock from the DTE. Values:Internal, External Default:Internal NOTICE: The External option is valid only in Packet mode. Tx Invert Clock Changes the clock edge used to sample data received from the DTE. Values:Disable, Enable Default:Disable Flow Control Selects the type of flow control to be used if the port is asynchronous. Values: None, Xon/Xoff, RTS/CTS Default: None

8300-A2-GB20-00 April 2003 2-21 Character Size Selects the number of bits required to make up one asynchronous character. Values: Five, Six, Seven, Eight Default: Eight Parity Sets the parity bit. Values: None, Odd, Even Default: None Stop Bit Selects the number of bits required to end the asynchronous character. Values: 1, 2 Default: 1 RTS Request To Send determines the source from which the unit reads the RTS signal status. If set to Normal, the unit gets RTS from the DTE on the Serial interface. If set to Forced True, RTS is always perceived as On. Values: Normal, Forced True Default: Normal RTS/CTS Delay Request To Send/Clear To Send determines how long the unit waits before it changes the level of CTS to match RTS when the CTS parameter is set to Internal. Values: Normal (~30 ms delay), Long (~100 ms delay) Default: Normal CTS The Clear To Send can be set to Forced True, Forced False, or Internal. If this parameter is set to Internal, the CTS control lead follows the Request to Send (RTS) control lead from the DTE after a delay of a duration established by the RTS/CTS Delay parameter (see RTS/CTS Delay on page 2-21). Values: Forced True, Forced False, Internal Default: Forced True DCD Data Carrier Detect can be set to Forced True, Forced False, or Internal. If set to Internal, DCD is On when network carrier is being received from the remote end, and is Off when network carrier is not being received from the far end. Values: Forced True, Forced False, Internal Default: Forced True DSR Data Set Ready can be set to Forced True, Forced False, or Internal. The Internal option sets DSR On if the port is enabled and Off if the port is disabled. Values: Forced True, Forced False, Internal Default: Forced True Current Pin Status Displays the Current Pin Status of the DTE Serial port pins. DTR Alarm Control and Status Table In addition to the configurable fields, the Serial screen displays a table that lets you set the Data Terminal Ready (DTR) Alarm Control parameters and view the current DTR Alarm Status. Choices for DTR Alarm Control are Enable and Disable; the default setting is Disable. Setting DTR Alarm Control to Enable allows the unit to generate an alarm

2-22 April 2003 8300-A2-GB20-00 upon loss of DTR, which occurs when the Serial port detects that the DTR signal is low. The DTR Status field indicates the current state of the DTR alarm. To make changes to a Serial port parameter, simply set the parameter to the desired selection and press the Submit button. 10/100 Ethernet (IP Service Details) The 10/100 Ethernet (IP Service Details) screen (Figure 2-18) lets you configure the IP parameters described below. Figure 2-18. 10/100 Ethernet (IP Service Details) Screen Unit IP Address A unique Network address assigned to this unit. Subnet Mask Defines the Network portion of the unit’s IP Address. Gateway IP Address IP Address of the default gateway (router) on the LAN side of the unit. DHCP Client If DHCP Client is enabled at power-up, the unit will request its IP, Mask, and Gateway addresses from a DHCP server located on the LAN side of the unit, and the unit will use these addresses. If the DHCP request is unsuccessful, the unit will use the configured addresses shown on this screen. Client Identifier Displays a unique identifier for a specific IP address. Ethernet Enables or disables a remote unit’s Ethernet port. Physical Address Displays unique MAC address.

The ATM Service Details screen lets you access the configuration parameters described in the paragraphs below. Figure 2-25. ATM Service Details Screen The Configuration table on the ATM Service Details screen is used to set the following configuration parameters: Max VCC (Virtual Channel Connection) – Represents the maximum number of Virtual Channel Connections on this ATM link. By default, each VCC will equally share the available bandwidth. This value should be kept as low as possible to avoid wasting bandwidth. The default value is 4.

2-28 April 2003 8300-A2-GB20-00 Max VPI Bits – The default Max Virtual Path Identifier Bits value is 3 for VPI values ranging from 0 to 8. Max VCI Bits – The default Max Virtual Channel Identifier Bits value is 6 for VCI values ranging from 32 to 63. Oversubscription Factor − The current over-subscription factor for this ATM interface. Used for VBR and UBR VC connection admission control to allow either the VBR or UBR service category connections to collectively use more bandwidth than is available to make use of the statistical multiplexing of the connections. Values range from 1 to 10. A value of 1 indicates no oversubscription. A value of 5 indicates 5 times oversubscription of both VBR and UBR is permitted. NOTICE: CBR connections cannot be oversubscribed Also, if CES is in use on the interface, PCR is limited for all AAL5 connections to the amount the line rate can support above the commitment for CES, and the oversubscription applies only to bandwidth above the CES commitment. To change an ATM Service configuration, enter the desired value for each parameter and click on the Submit button. The Status table provides the following status information on the circuits: OperStatus (Operation Status) - the current operational status for the ATM interface. Opened VCCs − the current number of open virtual channel connections. Unopened VCCs − the current number of unopen virtual channel connections. Line Bandwidth − the current line bandwidth on the ATM Network interface expressed in cells per second. AAL5 Bandwidth − the current ATM bandwidth available for AAL5 traffic. This value is the line bandwidth less the bandwidth needed for AAL1 CES. QoS 0 PCR − the current peak cell rate configured for any virtual channels using default QoS profile. The Bandwidth Status table provides bandwidth information for three service categories showing the allowed and allocated bandwidth for each. The ATM Service Details screen provides the user-activated buttons described below. Button Function Submit Sets any values that have been changed. ATM Statistics Displays the current ATM statistics. Virtual Channels Displays configured VCCs. QoS Profiles Displays configured QoS profiles.

8300-A2-GB20-00 April 2003 2-29 ATM Statistics Screen Clicking on the ATM Statistics button on the ATM Service Details screen will display the screen shown in Figure 2-26. Figure 2-26. ATM Statistics Screen There are ninety-six 15-minute buckets available for ATM statistics. If the unit is powered on at 01:00 PM, the first interval will be completed at 01:15 PM; subsequent intervals would be completed at xx:30, xx:45, xx:00 and xx:15. Interval 1 is always the latest (most recent) interval, and interval 96 will always be the oldest. The table on the ATM Statistics screen shows a summary that includes all 96 buckets. You can choose to see the statistics for any given bucket by selecting the desired Period Index from the pull-down menu and clicking the Submit button. Alternatively, you can display all intervals at once by clicking the All ATM Intervals button beneath the table. The MIB (ipad.mib) describes each available statistic. The ATM Statistics table is divided into three sections: Transmit, Receive and Status. Each section provides real-time updates on the following statistics: Transmit section — Frames − current number of good frames transmitted — Errored Frames − current number of frames in error — Bytes − current number of bytes sent Receive — Frames − current number of good frames received — Errored Frames − current number of frames in error — Bytes − current number of bytes received. Status

2-30 April 2003 8300-A2-GB20-00 — Opened VCCs − number of opened VCCs — Unopened VCCs − number of unopened VCCs Use the pull-down menu in the Period Index row of the table to select the interval for which you want to see ATM statistics. You may choose any of the 96 intervals, the current statistics, or a summary of the past 24-hour period. The default setting is a Summary of all intervals. ATM Statistics (All Intervals) Screen Clicking on the All ATM Intervals button on the ATM Statistics screen will display a table (Figure 2-27) that summarizes the transmit and receive statistics for the current time interval and all intervals recorded during the current 24-hour reporting period. Figure 2-27. ATM Statistics Table (All Intervals) Screen ATM Virtual Channels Screen Clicking the Virtual Channels button on the ATM Service Details screen will display a table (Figure 2-28) of all Virtual Channels on a specific ATM service along with their state and alarm conditions.

8300-A2-GB20-00 April 2003 2-31 Figure 2-28. ATM Virtual Channels Screen The ATM Virtual Channels screen displays status information on the following parameters listed below. The QoS Profile and Admin Status are configured or changed on the Virtual Channel Details screen (Figure 2-29). VPI Virtual Path Identifier number. VCI Virtual Channel Identifier number. Admin Status Current Admin Status. Values: Up, Down, Testing Operation Status Current Operation Status. Values: Up, Down, Testing Last Change Time and date of the Last Change. QOS Profile Current QOS profile in use. The default profile is 0 (zero), which is used for UBR traffic. When QOS profile 0 is used, the available bandwidth will be equally shared among all configured channels. QOS 0 cannot be modified. If one virtual channel requires more bandwidth than others, configure another QOS profile and set its peak cell rate (PCR) to the required value. However, the sum of the PCRs of all configured channels must be no greater than the available AAL5 bandwidth. The available PCR on an SHDSL-ATM link with a line rate of 2304 kbps is about 5433 cells per second. When oversubscription is used, the sum of the PCRs for VBR or UBR channels may exceed the AAL5 bandwidth. Encapsulation Type Encapsulation Type used. Default is Routed IP, which uses RFC 1483 LLC encapsulation. If Serial PPP is selected, PPP traffic received from the Serial port will be sent over the ATM port using RFC 1483 PPPoA encapsulation. There can be only one VCI configured for Serial PPP.

2-32 April 2003 8300-A2-GB20-00 Serial HDLC is similar to Serial PPP except, when you select Serial HDLC, data is encapsulated transparently. Any type of HDLC traffic will be supported. Because this is not a standard encapsulation, an 8300 Endpoint must reside at each end of the connection. Even if Serial HDLC or Serial PPP encapsulation is configured, routed IP traffic received on this channel will be forwarded to the IP Gateway, if IP Gateway is configured. Values: Serial PPP, Routed IP, Serial HDLC Traffic Type Traffic type used. This is a read-only parameter. Values: CBR, UBR, VBR Row Status Current status of the VCC. Values: Active, Not In Service, Not Ready Adding a New Virtual Channel To create a new virtual channel, enter the desired VPI/VCI values in the appropriate fields near the bottom of the screen and click on the Add Virtual Channel button. If the newly added virtual channel is within the maximum VCC parameter, it will be activated immediately. NOTICE: When adding a Virtual Channel, the value for VPI may be 0 and above, but for VCI, must be 32 and above. Click on a listed VPI to bring up the Virtual Channel Details screen (Figure 2-29) where you can view and/or change parameters. Figure 2-29. Virtual Channel Details Screen

8300-A2-GB20-00 April 2003 2-35 Figure 2-32. CES Service Details Screen From this screen, you can access and change the parameters listed below. The new parameters are saved when you click on Submit and then perform a Save and Restart. VPI Determines VPI used for this CES Internet Working Function (IWF). The default is 0. VCI Determines VCI used for this CES IWF. The default is 33. Service Type Determines if T1/E1 service is structured (Nx64 kbps with or without signaling) or unstructured (2.048 or 1.544 Mbps raw data stream). You must configure the Service Type to correspond with the desired CBR port framing and channel rate in accordance with the Format Relationships Table (Table 2-1) on page 2-38. Timing Determines the CES services clocking mode, which maps to the transmit clock source of the CBR interface and Serial interface (if configured for a CES service). When Adaptive timing is selected, the receive AAL1 payload buffer is monitored for predetermined threshold levels to control the frequency of the interface clocks. When the buffer depth exceeds the predetermined upper threshold, the interface clock frequency is increased to cause the buffer to drain more quickly. If the buffer depth falls below the predetermined lower buffer threshold, the interface clock frequency is decreased to cause the buffer to drain less quickly. Both lower and

2-36 April 2003 8300-A2-GB20-00 upper threshold levels are used in conjunction with Cell Delay Variation to provide hysteresis around threshold levels. Values: Synchronous, Adaptive Default: Synchronous AAL1 Format Specifies AAL1 format − Basic, E1Cas, Ds1SfCas, or Ds1EsfCas. This value must be set in accordance with the Format Relationships Table (Table 2-1) on page 2-38 for proper operation. Payload Scrambling The 8300 Endpoint scrambles/descrambles cell payload bytes at the physical layer interface using an x43 + 1 polynomial. You may enable/disable the scrambling function on the CES Service Details Screen. Normal operation will have Payload Scrambling enabled. (See Figure 2-32. on page -35.) Partial Cell Fill Byte Count Sets the number of user octets per cell. Setting this parameter to 0 disables Partial Cell Fill, and all cells are completely filled before being sent. Rx Cell Delay Variation (10 µs) Maximum cell arrival jitter in 10-µs increments that the reassembly process will tolerate in the cell stream without producing errors on the CBR service interface. Default is 100 for a 1000-µs Cell Delay Variation (CDV). Cell Loss Integration (ms) Time in milliseconds for the cell loss integration period. If cells are continuously lost during the specified period of time, Cell Loss Status is set to Loss. Default is 2500 ms. Administrative Status Sets the Administrative Status of the CES IWF. Up indicates traffic flow is enabled, and Down indicates traffic flow is disabled across the CES IWF. NOTICE: To enable a new parameter, rather than saving and restarting, set the Administrative Status to Down, and click on the Submit button at the bottom of the screen. Then set the Administrative Status to Up, and click on the Submit button once again. Operational Status Displays the Operational Status of the CES IWF. The state will be Down or Unknown if the supporting CBR or ATM interface is down or unknown. Status Reassembly Cells Displays the number of cells received by the CES IWF. This number excludes cells that have been discarded for any reason, including cells not used due to their being misinserted or discarded while the reassembler was awaiting synchronization. Header Errors Displays the number of AAL1 header errors detected, including those that have been corrected. Header errors include correctable and uncorrectable CRCs and bad parity.

8300-A2-GB20-00 April 2003 2-37 Pointer Reframes Displays the number of events in which the AAL1 reassembler found a Structured Data Pointer (SDT pointer) where it was not expected, making it necessary to reacquire the pointer. Pointer Parity Errors Displays the number of events in which the AAL1 reassembler has detected an SDT pointer parity check failure. AAL1 Seq Errors Displays the number of times the sequence number of an incoming AAL1 frame causes a transition from the sync state to the out of sequence state. Lost Cells Displays the number of cells detected as lost in the network prior to reaching the destination CES IWF AAL1 layer processing. As an example, the number of lost cells may be detected as a result of AAL1 sequence number processing. Misinserted Cells Displays the number of AAL1 sequence violations, which the AAL Convergence Sublayer interprets as misinserted cells. Buffer Underflows Displays the number of times the CES reassembly buffer underflows. Buffer Overflows Displays the number of times the CES reassembly buffer overflows. Cell Loss Status Displays Loss when cells are continuously lost during the specified Cell Loss Integration Period. When a valid cell(s) is received, this condition is cleared, and No Loss will be displayed. Configuring the 8300 Endpoint for CES involves setting parameters not only on the CES Service Details screen (page 2-35), but also on the CBR screen (page 2-14); in some cases, the Serial screen (page 2-19); and the Channel Table Details screen (page 2-38). The table below shows the settings required to maintain the proper relationships among CBR framing, the CES Service Type, the CES AAL1 format, and the Channel Rate.

8300-A2-GB20-00 April 2003 2-39 The Channel Table Details screen lets you establish the Rate, Service, and Idle Pattern parameters for any available channel. The screen parameters are described below. Rate The unit can operate at any data rate that is a multiple of 56 or 64 kbps. You must set this value in accordance with the Format Relationships Table on page 2-38 for proper operation. Values:56K/Signaling, 64K Default:64K Service Specifies the service to which this channel is allocated. Service Index 0 indicates the channel is not used or is idle. Service Index 4 indicates the channel is allocated to the CBR interface. Service Index 5 indicates the channel is allocated to the Serial interface. Idle Pattern Selects the idle pattern sent by the unit and lets the unit determine if the idle pattern has been sent by the other end. Values:0−FF (Hex) Default:7F NOTICE: Only channels with a non-zero Service parameter value are assembled into ATM cells and transported across the SHDSL network. Similarly, received ATM cells should only contain data for channels with a non-zero Service parameter value. When reassembling the data stream from the received ATM cells, only the channels with a non-zero Service parameter will be assigned data from the ATM cells. The non-active channels with a Service parameter of 0 will be filled with an idle pattern. The number of channels you can allocate for the CES service depends on the available SHDSL bandwidth. The table below shows the maximum number of channels you can allocate for CES for each possible SHDSL data rate. If the required CES bandwidth exceeds the available SHDSL bandwidth, the unit will not allow you to configure the CES service.

2-40 April 2003 8300-A2-GB20-00 Table 2-2.

8300-A2-GB20-00 April 2003 2-41 Serial CES Configuration The 8300 Endpoint has the capability to multiplex/demultiplex the Serial interface data stream with the CBR interface data stream. The multiplexing/demultiplexing is external to the AAL1 SAR; the user controls it by designating time slots for the CES service on the CBR or Serial port. To configure the Serial interface for CES service, perform the following steps: 1. On the Services screen (page 2-25), click on the Service Index associated with the Serial interface (5). This will cause the unit to display the Service Details screen for the Serial interface. On the Service Details screen (page 2-26), select CES from the Type pull-down menu. 2. On the Serial screen (page 2-19), configure the Serial interface to your requirements. You must set the Mode parameter to DCE. If the required time slots for the Serial interface are contiguous and not already allocated to the CBR port, you may allocate the required channels on the Serial screen. If you have not allocated channels for the Serial interface on the Serial screen, use the Channel Table Details screen (Step 3 below) to specify the channels for the Serial CES service. 3. On the Channel Table Details screen (page 2-38), set the desired channel’s Rate parameter to 64K, and the Service parameter to the Service Index for the Serial interface (5). Valid Channel Ranges for Serial and CBR Interfaces The range of channels available to the Serial interface depends on the type of CES service. The table below shows the range of channels available to the Serial and CBR interfaces for each type of CES service. The type of CES service and the SHDSL data rate shown in Maximum CES Channels (Table 2-2) on page 2-40 limit the total number of channels that can be allocated to the Serial interface.

2-42 April 2003 8300-A2-GB20-00 HDLC/PPP Service This service has no configurable parameters. CES Service Type Description Available Serial Interface Channel Range Available CBR Interface Channel Range Comments Basic E1 1−31 1−31 Serial or CBR interface channels may be any arbitrary set within the available channel range. Basic T1 (ESF) 1−24 1−24 Serial or CBR interface channels may be any arbitrary set within the available channel range. Basic T1 (D4) 1−24 1−24 Serial or CBR interface channels may be any arbitrary set within the available channel range. E1 w/Signaling 1−311 1-15, 17-31 Serial interface channels may be any arbitrary set within the available channel range. CBR interface channels may not include Channel 16.2 T1 w/Signaling (ESF) 1−24 1−24 Serial or CBR interface channels may be any arbitrary set within the available channel range. T1 w/Signaling (D4) 1−24 1−24 Serial or CBR interface channels may be any arbitrary set within the available channel range. Unstructured E1 0−31 0−31 Multiplexing channels between the CBR and Serial interface is not allowed for an unstructured service. All channels may be allocated to either the Serial interface (Service parameter 5), or the CBR interface (Service parameter 4), or disabled (Service parameter 0). Unstructured T1 None3 1−24 All channels must be allocated to the CBR interface (Service parameter 4) or disabled (Service parameter 0). 1 Channel 16 (time slot 6) can be used for the Serial CES service without affecting E1 signaling. The E1 signaling information is extracted from the CBR interface data stream prior to multiplexing it with the Serial interface stream. Therefore, replacing channel 16 (time slot 16) with Serial interface data will not affect the assembly or reassembly of the signaling data in the CES data stream. 2 The signaling information in the channel is automatically extracted in this mode and assembled in the signaling substructure of the ATM payload. Including channel 16 in the CBR interface data stream would duplicate the data transmitted in the signaling substructure and is therefore not needed. 3 An Unstructured T1 CES service is not compatible with a Serial interface CES service because the Serial interface does not support a 1.544 MHz clock rate. However, you may use a Basic T1 CES service and allocate all 24 channels to the Serial interface CES service resulting in a 1.536 MHz clock rate.

8300-A2-GB20-00 April 2003 2-43 Applications The Applications screens describe configuration tables and statistics for Layer 3 and above that do not map to a specific service or interface. Service Aware The Service Aware function recognizes IP traffic on the WAN and counts the number of frames and bytes passed for a specific service based on filters by VPI/VCI, by IP Address, and by IP Port. Each row of the Service Aware table represents a specific set of filter parameters known as a rule. Each rule is established through the Rule Config screen, which is accessed by clicking the Rule Details button at the bottom of the Service Aware screen. The Service Aware screen (Figure 2-34) provides a table showing these filtered packet counts for up to 10 rules. This table indicates which Service Aware filters are enabled or disabled, and shows the specific VPI/VCI, IP Address, and IP Port by which the IP traffic is filtered. In addition, this table shows the Tx Alarm Threshold and the current Tx Alarm status (if enabled) for each rule. Figure 2-34. Service Aware Screen The Service Aware screen provides a Clear Alarms user-activated buttons:

2-44 April 2003 8300-A2-GB20-00 Rule Details Screen Access the Rule Details screen (Figure 2-35), where you can establish Service Aware parameters, by selecting the appropriate hyperlink from the Index column in the above screen. To establish a rule, select the desired rule configuration options, provide the appropriate filter information where required, and click on the Submit button at the bottom of the screen. Figure 2-35. Rule Details Screen The paragraphs below describe the rule configuration parameters and their options. Service Selects the service to which the rule applies. Select from a pull-down menu that lists available services. VPI Selects the VPI to which the rule applies. VCI Selects the VCI to which the rule applies. Filter By VPI/VCI Enables or disables filtering of the IP traffic in accordance with the specified VPI/VCI. NOTICE: To use this filter, you must specify both the Service and VPI/VCI parameters in the Rule Config screen. IP Address Establishes the IP Address by which the rule will filter IP traffic (if enabled). IP Mask Represents a range of IP Addresses defined so that only machines with IP Addresses within the range defined by the mask are allowed to access an Internet service. To mask a portion of the IP Address, replace it with the wild card character 0 (zero). (For example, 192.44.0.0 represents every computer on the Internet with an IP Address beginning with 192.44.)

8300-A2-GB20-00 April 2003 2-45 Filter By IP Address Enables or disables filtering of the IP traffic by the IP Address specified in the IP Address or IP Mask field. IP Port Establishes the IP port by which the rule will filter IP traffic (if enabled). Filter By IP Port Enables or disables filtering of the IP traffic by the IP port specified in the IP Port field. Tx Alarm Threshold Specifies the threshold (in bps) for the Transmit Alarm on this rule. Tx Alarm Displays the current status of the Transmit Alarm. Traffic Meter Statistics Screen The Traffic Meter Statistics (Figure 2-36) screen displays the number of frames and octets sent over a VPI/VCI that have been counted in accordance with the Service Aware rule that has been established for a Service. As such, it is ATM specific (i.e., VPI/VCIs only occur in ATM links). In addition, this screen provides data rate performance information for the period of time specified in the Period Index field (see below). Access this screen by clicking on the appropriate Statistics hyperlink on the Service Aware screen. Figure 2-36. Traffic Meter Statistics Screen The Traffic Meter Statistics screen reports Transmit, Receive, and Performance statistics on the following parameters: Tx Frames Tx Octets Rx Frames Rx Octets

2-46 April 2003 8300-A2-GB20-00 Rate Peak – the peak data rate for the viewed period (see below) Rate Average – the average data rate for the viewed period (see below) The Period Index field is used to define the period of time for which the Traffic Meter statistics will be reported. It represents the 24-hour, 15-minute buckets index. Selecting a period and then clicking the Submit button will display the traffic meter statistics for that period. The user-selectable options are listed below. Click on the All Traffic Meter Intervals button to see the screen shown below in Figure 2-37. Figure 2-37. All Traffic Meter Stats (All Intervals) Screen SNMP The unit detects and reports E1 network alarms and provides several options for reporting them, one of which is SNMP traps. When a network alarm occurs, the unit sends a trap message to as many as eight destinations on your network. The unit will report each alarm by transmitting an SNMP trap to each non-zero Trap IP Address. The SNMP Details screen (Figure 2-38) lets you configure the SNMP parameters described below. Figure 2-38. SNMP Details Screen Read Community Accepts a character string identifying the group authorized to perform read operations. The default setting is Public.

8300-A2-GB20-00 April 2003 2-47 Write Community Accepts a character string identifying the group authorized to perform write operations. The default setting is Private. Trap Community Accepts a character string, which is included in SNMP traps generated by the unit. The default setting is Public. Trap IP Address Accepts the IP Address of a network device where alarm reporting traps are to be sent. Trap Log A trap is a mechanism that permits a device to send an alarm for certain network events to an SNMP management station. The Trap Log screen (Figure 2-39) shows all generated traps. The table shown in this screen lists each trap by its Index number, and displays the type of error captured by the trap (Trap Number) and the date and time that the trap was stored (Time Stamp). Click the hyperlink at the top of the screen to display the latest trap information in the table. To remove all trap information stored in memory, click the Delete All Traps button at the bottom of the screen (not shown in the figure below). Figure 2-39. Trap Log Screen

2-48 April 2003 8300-A2-GB20-00 Top Talkers Clicking on the Top Talkers link in the navigation tree displays a screen (Figure 2-40) used to set the parameters for and initiate the generation of a list of IP Addresses ranked in terms of the number of frames and octets they have transmitted during a specified reporting period. This report allows MIS managers to determine who is generating the most traffic on a WAN based on IP Addresses. Figure 2-40. Top Talkers Screen To generate a Top Talkers report, enter the desired report size in the appropriate field, and then click the Submit button. Duration Establishes the amount of time (in seconds) for which the Top Talkers report will capture IP traffic; typically this value is 900 seconds (15 minutes). Time Remaining Establishes the amount of time (in seconds) for which the Top Talkers report will capture IP traffic; typically this value is 900 (15 minutes). As soon as you initiate generation of the report by pressing the Submit button, the Duration value is copied over to the Time Remaining field. Click on the hyperlink to see how much time is left before the report is completed. Requested Report Size Establishes how many IP Addresses will be reported as the Top Talkers. NOTICE: While you may request any number, the unit is internally limited to a maximum of 20. As soon as the specified Duration for the report has elapsed, the screen will refresh itself and the resulting report-specific information will be displayed in the outlined box at the bottom of the screen. This report comprises elements as defined in the following paragraphs. Report # This field displays a unique number used to identify the generated report. This number is generated automatically, is incremented sequentially for each report, and can be used by management stations for automatic polling (via the ipadv2.mib).

8300-A2-GB20-00 April 2003 2-49 Size Displays the actual number of IP Addresses identified as Top Talkers in the generated report. The maximum report size is 20. Start Time Displays the time at which the Top Talkers report was initiated (based on System Up Time). System Up Time Displays the amount of time that the unit has been operational since it was turned on or last reset. The Top Talkers table reports in descending order the IP Addresses that have generated the most traffic during the requested report’s duration. For each IP Address listed, the report displays the number of Rx frames, Rx octets, Tx frames, and Tx octets that have been passed across it. In addition, the Timestamp field indicates the time at which a packet was examined for the specified IP Address. IP Gateway The IP Gateway is a feature that allows routing of IP packets from one network to another using static routes configuration and/or dynamic routing. The IP Gateway uses Routing Information Protocol (RIP) 1 or RIP 2 or Open Shortest Path First (OSPF) routing. RIP 1 and RIP 2 are protocols that allow exchange of routing information between two routers. With that information exchange, a router can build its own routing tables that later can be used for routing IP packets. OSPF is a shortest path first (SPF) or link-state protocol. OSPF is also an internal gateway protocol (IGP) that distributes routing information between routers in a single autonomous system (AS). OSPF chooses the least cost path as the best path. While RIP is ideal for small- to medium-sized networks, OSPF is more suitable for complex networks with a large number of routers. OSPF provides equal cost multipath routing where packets to a single destination can be sent via more than one interface simultaneously.

2-50 April 2003 8300-A2-GB20-00 Figure 2-41. IP Gateway Details Screen RIP Parameters RIP Enable Globally enables RIP 1, RIP 2, or No RIP. Values: Disable, Enable RIP1, Enable RIP2 Default: Enable (RIP2) RIP Trust Neighbors Globally enables the trusted neighbors feature. If there is a list of trusted neighbors in an IP Gateway, only RIP packets coming from those trusted neighbors will be used to build the internal routing table. Values: Enable, Disable Default: Enable RIP Interval Interval for RIP packet to be sent. Default is 30 seconds. RIP Domain Value representing the RIP domain. Default is 0. OSPF Parameters OSPF Enable This Protocol is suitable for complex networks with a large number of routers. If a large network is involved, OSPF may be the solution for the user. Values: Disable, Enable Default: Disable OSPF Router ID This 32-bit number assigned to each router running the OSPF protocol uniquely identifies the router within an autonomous system. Each router requires a unique router ID. Default is the LAN IP Address of the unit.

8300-A2-GB20-00 April 2003 2-51 The IP Gateway screen provides the following user-activated buttons: Circuit Table Screen Access this menu by clicking on the Circuit Table button at the bottom of the IP Gateway menu.

Values: 1−3600 Default: 1 OSPF Router Priority This 8-bit unsigned integer ranges from 1 to 255 and assigns priority to one of two routers attached to the same network; without an assigned priority, both routers attempt to become the designated router. Values: 1−255 Default: 1

2-54 April 2003 8300-A2-GB20-00 OSPF Hello Interval The time in seconds between the Hello packets that a router sends on a circuit. This value is also advertised in the router’s Hello packets and must be identical for all routers on the same network. The smaller the Hello Interval, the sooner topological changes are detected (but then more traffic is created). Values: 1−65535 Default: 10 OSPF Dead Interval The number of seconds that a router’s Hello’s have not been received before its neighbors declare the router down. The value must be the same as the value on the network. Values: 1−65535 Default: 40 OSPF Auth Key When configured, this parameter allows an authentication procedure to be executed on the OSPF header. If the 64-bit (8 character) password does not correspond, the packet is thrown away. Values: 64 bits (8 characters) Default: 8 spaces (no authentication) The Circuit Details screen provides the following user-activated buttons: Static Route Table Screen Under some circumstances, it may not be necessary for a router to learn a route using ordinary means such as RIP or OSPF. It is possible under these circumstances for you to add a route to the route table of a router. The Static Route Table is always associated with a circuit. Access this menu by selecting the Static Route Table from the RIP Parameters Table on the IP Gateway menu. Figure 2-44. Static Route Table Screen Endpoint Endpoint name (or interface) through which to send the IP packet to reach the Target IP Address. By default, the first circuit is always the LAN circuit. WAN circuit endpoint names are taken from the VPI/VCI number. For example, VPI 0/VCI 32 will have P0-C32 for an endpoint name. The pull-down menu will display a list of Button Function Submit Sets any values that have been changed. Circuit Table Returns you to the previous screen.

2-56 April 2003 8300-A2-GB20-00 Target IP Address Represents the target network that you want this router to reach. Values: 0.0.0.0−255.255.255.255 Default: 0.0.0.0 Target IP Mask Mask of the target network. Values: 0.0.0.0−255.255.255.255 Default: 0.0.0.0 NOTICE: Setting the Target IP Address and Target IP Mask to 0.0.0.0 defines the default route for this unit. Because a unit can have only one default route, if a default route is configured as a WAN route on the above screen, the Gateway address configured on the 10/100 Ethernet screen must be left blank. Likewise, if a Gateway is configured on the 10/100 Ethernet screen, it becomes the default route, and no WAN default route can be configured on a Static Route. Next Hop IP Address: IP Address of the next device in the route. Cost Cost of using that route. Values: 0−65535 Default: 1 Route Status Indicates whether or not the current route is enabled. Values: Enable, Disable, Enable and Advertize Default: Enable The Route Details screen provides the following user-activated buttons: Dynamic Route Table Screen Access this menu by clicking on Dynamic Route Table on the Static Routes menu. This table shows both dynamic and static routes. Please note that not all parameters are necessarily defined, depending on whether or not the routes were learned dynamically. Primarily, the most useful information is included in "Destination," "Interface Index," and "Mask" columns. Button Function Submit Sets any values that have been changed. Static Route Table Returns you to the previous screen. Delete Route Deletes the route currently displayed.

Type Direct or Indirect. Protocols Local Age 0 Mask Mask of the destination network. Static ARP Table Screen ARP (Address Resolution Protocol) is used by the router to dynamically associate a high-level IP Address to a low-level physical hardware address. ARP packets are only sent across a single physical network. There are some cases when an IP-compatible device does not support ARP or ARP is deliberately disabled (for security). In these cases, instead of using ARP to dynamically update the router internal MAC <-> IP Address Table, this menu can force an entry into that table. This entry never times out. At least one circuit must be defined to create a Static ARP Table entry because an ARP entry is always associated with a circuit. The static ARP table is useful when a Host does not respond to an ARP request. Access this menu by selecting Static ARP Table from the RIP Parameters screen on the IP Gateway menu.

This includes the state of the route’s interfaces and adjacencies. Each link state advertisement is flooded throughout the routing domain. The collected link state advertisements of all routers and networks form the protocol's topological database. Values: Yes, No Default: No The Area Details screen provides the following user-activated buttons: Virtual Link Table Screen To permit maximum flexibility, OSPF allows the configuration of virtual links to enable the backbone area to appear contiguous despite the physical reality. In OSPF, the backbone is defined as an Area ID of 0.0.0.0. This backbone cannot be disconnected in any way or some areas of the Autonomous System become unreachable. This is because all inter-area traffic must go through the backbone. In fact, the backbone is responsible for all inter-area routing information distribution. It is possible that an area cannot be connected directly to the backbone; in this case a virtual link is used (see Figure 2-53). To establish or maintain the connectivity of the backbone, virtual links can be configured through non-backbone areas. Basically, virtual links are used to connect components that are otherwise not connected to the backbone. A virtual link is treated by OSPF as a point-to-point unnumbered network joining two area border routers. The virtual link must be configured in both of the area border routers. A virtual link is defined by the following two parameters: The Router ID of the virtual link’s other endpoint The non-backbone area across which the virtual link goes through. Access this screen by selecting the Virtual Link Table from the OSPF Parameters table on the IP Gateway screen. Button Function Submit Sets any values that have been changed. Area Table Returns you to the previous screen. Delete Area Deletes the currently defined Area.

Figure 2-55. Originate Ping Screen Destination IP Address Destination IP Address of sent Ping request messages. Number to Send Number of Ping request messages to send. Values:1−10,000 Default:5 Ping Size (Bytes) Number of bytes in a Ping request message. Values:4−4096 bytes Default:64 bytes Ping Reply Timeout (sec) Number of seconds to wait for a reply to a Ping request message. Values:1−60 s Default:1 s Ping Status Shows the number of pings returned versus the number requested, and providing minimum, average, and maximum statistics.

8300-A2-GB20-00 April 2003 2-65 The Originate Ping screen provides the following user-activated buttons: Network Address Translation (NAT) NAT is a method of connecting multiple computers to the Internet (or any other IP network) using one IP Address. This lets users cost-effectively and efficiently connect their networks to the Internet. Whether on a global or local port, NAT provides translation only upon receipt of a packet, which NAT will translate, not translate, or filter, depending on the user-specified parameters (further described below). If the decision is made to translate, the packet will be modified internally, and eventually sent on to the IP Gateway to be processed. If the decision is made not to translate, the packet will not be modified in any way. If the decision is made to filter, the packet will be discarded without any further action required. NOTICE: You must Save and Restart for any changes in NAT configuration parameters to take effect. NAT Details Screen The NAT Details screen (Figure 2-56) lets the user configure the NAT global parameters described below. Figure 2-56. NAT Details Screen Enable Enables or disables NAT. Default is Disable. Mode Selects the Network Address Port Translation (NAPT) mode or the Basic NAT mode. In NAPT mode, all hosts on the Global (public) side view all hosts on the Local (private) side as a single internet host (one IP Address). In Basic NAT mode, the Global IP Address is assigned as a Class C host address (Mask of 255.255.255.0). Each private IP Address on the Local side is mapped to a Class C public address on the Global side. In other words, if there are 30 hosts on the Button Function Submit Sets any values that have been changed. Start Ping Starts sending Ping messages. Stop Ping Stops sending Ping messages. Reset Stats Clears all counts activity.

2-66 April 2003 8300-A2-GB20-00 private (Local) side, 30 public (Global) addresses are required. The default is NAPT. Global IP Addr Global IP Address used in NAPT mode. Must be a valid Class C address. Default is LAN IP Address. Global Mask IP Mask associated with defined Global IP Address. Default is LAN IP Mask. ICMP Default Addr Default source address used to answer any ICMP request. Default is LAN IP Address. ICMP requests are not transferred from the Global to the Local side. Rather they are answered by the unit itself since Local addresses are private and do not receive unsolicited requests. Filter Non Local Address Discards any packet with non corporate source address. Default is Enable. The screen parameters listed below are related to the NAT Control Block Timer. Note that default values should be in accordance with most NAT applications. The timers’ values minimize NAT resources. Generally, when a timer has expired, the resources used are no longer needed. Those resources will then be available for other connection resources. IP Entry Timer The maximum time (in seconds) NAT will use resources when not using TCP, UDP, or ICMP. Values: 0−65535 Default: 120 TCP Connection Timer The maximum time (in seconds) NAT will use resources when attempting to establish a TCP connection.

Figure 2-60. NAT Static UDP Translation Details Screen NAT Port Table Screen The parameters on the NAT Port Table screen (Figure 2-61) define the NAT global/Internet and local/Corporate ports. These parameters are configured in the NAT Ports Details screen shown in Figure 2-62. Access the NAT Port Details screen by clicking on the Index number of the desired port on the NAT Port Table screen. Figure 2-61. NAT Port Table Screen Endpoint The Endpoint name of the circuit associated with the LAN or WAN port. Default is LAN for the first port. Enable Enables or disables the NAT port. Default is Enable. Default Translation Forces translation on a specific IP port regardless of the source IP Address. If Default Translation is set to Enable, the packet will never be discarded, but will always pass through the translation path. Therefore, any packets with a destination address different from the global/Internet network address will be processed by the IP Gateway, and may be routed to another port. If this parameter is set to Disable, no packet with a destination address different from the global/Internet address will be processed. Setting this parameter to Disable will override an Enable parameter set under Filter Non Local Address on the NAT Details menu.

2-70 April 2003 8300-A2-GB20-00 Type Defines whether this port is local or global. Default is LAN global. All others are local. IP Address IP Address of this port.

8300-A2-GB20-00 April 2003 2-71 IP Address Original IP Address of the host. NAT IP Address Translated IP Address of the host. Processed Packets Number of packets processed by NAT for this address. Dynamic Host Configuration Protocol (DHCP) DHCP provides a mechanism through which computers using TCP/IP can obtain protocol configuration parameters automatically through the network. The most important configuration parameter associated with DHCP is the IP Address. A computer must initially be assigned a specific IP Address that is appropriate to the network to which the computer is attached, and that is not assigned to any other computer on that network. If a computer moves to a new network, it must be assigned a new IP Address for that new network. DHCP can be used to manage these assignments automatically. DHCP has other important configuration parameters also, such as the subnet mask, default router, and Domain Name System (DNS) server. Using DHCP, a network administrator can avoid hands-on configuration of individual computers through complex and confusing setup applications. Instead, those computers can obtain all required configuration parameters automatically, without manual intervention, from a centrally managed DHCP server. DHCP is available on the 10/100 Ethernet port only. NOTICE: You must Save and Restart for any changes in DHCP configuration parameters to take effect. DHCP Server Details Screen The DHCP Server Details screen (Figure 2-64) lets you configure the parameters described below. Figure 2-64. DHCP Server Details Screen Enable Enables or disables the DHCP Server. Default is Enable.

2-72 April 2003 8300-A2-GB20-00 Number of Ports Defines the number of DHCP ports to be used. In this version, only 1 is a valid value. TTL Time to Live for any DHCP packet. Default is 64. Service Type Type of Service used by the DHCP Server packet. Default is 1. Lease Time Tells the DHCP client the number of seconds it can retain this IP Address. The client should make a new DHCP request within the specified amount of time to ensure the IP Address is not given to another PC. Default is 600 seconds. Primary DNS IP Addr If requested by DHCP client, the client then uses this address to resolve names of IP Addresses. Default is 0.0.0.0. Secondary DNS IP Addr If requested by DHCP client, the client then uses this secondary address to resolve names of IP Addresses. Default is 0.0.0.0. Domain Name Domain name to be used by all DHCP clients. Default is user’s server. Router IP Addr IP Address that all clients use for Gateway or Router. Default is 0.0.0.0. The DHCP Details screen provides the following user-activated buttons: DHCP Host Table Screen In some cases, it may be necessary to provide an IP station with a specific DHCP server name, which may be used by the IP station when making a DHCP request. That name is included on the DHCP Host Table screen (Figure 2-65), which identifies the DHCP server sending DHCP packets. This parameter is configured on the DHCP Host Details screen (Figure 2-66) accessed by clicking on an Index number. Figure 2-65. DHCP Host Table Screen Button Function Submit Sets any values that have been changed. Host Table Lists Host names (DHCP server identification).

2-76 April 2003 8300-A2-GB20-00 Bridge A Bridge operates at the physical network layer, connecting two or more networks and forwarding packets between those networks. For example, a Bridge will connect two or more physical Ethernet cable segments and forward Ethernet packets from one segment to the other. Bridges differ from routers in that bridges forward packets based on physical addresses rather than on the IP Addresses that routers use to forward packets. Bridges will not blindly forward packets from one network to others, however. Rather, it learns all local physical addresses and forwards packets based on those learned tables. This greatly reduces the number of broadcasted packets, thus saving valuable bandwidth. The Bridge Details screen shown in Figure 2-72 lets you access and configure the parameters described below. Figure 2-72. Bridge Details Screen From this screen, you may view the parameters described below. Enable Enables or disables Bridging capability. Values: Enable, Disable Default: Disable Group Multicast MAC Address MAC Address recognized by the Bridge as the group address for the Bridge Protocol Data Unit (BPDU) transfer between bridges. Values: Any valid Group Multicast MAC Address Default: 0180C2000000 Bridge ID Consists of a bridge priority and its own MAC Address. Values: 1−65535 Default: 2

8300-A2-GB20-00 April 2003 2-77 Hello Timer Specifies the BPDU broadcasting interval. Values: 1−65535 s Default: 10 s Max Age Timer Specifies the length of time a bridge will consider the network topology held in memory as valid. Values: 1−65535 s Default: 60 s Forward Delay Specifies the length of time to delay creation of a temporary loop in the network. Values: 1−65535 s Default: 5 s Filter Ageing Timer Specifies the length of time an entry in the lookup table will be held if no traffic is received from the specified MAC Address. Values: 1−65535 s Default: 300 s The Bridge Details screen provides the following user-activated buttons: Figure 2-73. Bridge Port Table The Bridge Port Table screen lets you view the parameters described below the Bridge Port Details screen.
