6 1. Introduction This manual’s command descriptions are based on the software release 2.00. The commands listed here are the subset of commands that are supported by the DXS-3600 Series switch. Audience This reference manual is intended for network administrators and other IT networking professionals responsible for managing the switch by using the Command Line Interface (CLI). The CLI is the primary management interface to the DXS-3600 Series switch, which will be generally be referred to simply as the “switch” within this manual. This manual is written in a way that assumes that you already have the experience and knowledge of Ethernet and modern networking principles for Local Area Networks. Other Documentation The documents below are a further source of information in regards to configuring and troubleshooting the switch. All the documents are available either from the CD, bundled with this switch, or from the D- Link website. Other documents related to this switch are: • DXS-3600 Series Hardware Installation Guide • DXS-3600 Series Web UI Reference Guide Conventions Convention Description Boldface Font Commands, command options and keywords are printed in boldface. Keywords, in the command line, are to be entered exactly as they are displayed. UPPERCASE ITALICS Font Parameters or values that must be specified are printed in UPPERCASE ITALICS. Parameters in the command line are to be replaced with the actual values that are desired to be used with the command. Square Brackets [ ] Square brackets enclose an optional value or set of optional arguments. Braces { } Braces enclose alternative keywords separated by vertical bars. Generally, one of the keywords in the separated list can be chosen. Vertical Bar | Optional values or arguments are enclosed in square brackets and separated by vertical bars. Generally, one or more of the vales or arguments in the separated list can be chosen. Blue Courier Font This convention is used to represent an example of a screen console display including example entries of CLI command input with the corresponding output. All examples used in this manual are based on the DXS-3600-32S switch in the DXS-3600 Series. Notes, Notices, and Cautions Below are examples of the three types of indicators used in this manual. When administering your switch using the information in this document, you should pay special attention to these indicators. Each example below provides an explanatory remark regarding each type of indicator.

7 NOTE: A note indicates important information that helps you make better use of your device. NOTICE: A notice indicates either potential damage to hardware or loss of data and tells you how to avoid the problem. CAUTION: A caution indicates a potential for property damage, personal injury, or death. Command Descriptions The information pertaining to each command in this reference guide is presented using a number of template fields. The fields are: • Description - This is a short and concise statement describing the commands functionality. • Syntax - The precise form to use when entering and issuing the command. • Parameters - A table where each row describes the optional or required parameters, and their use, that can be issued with the command. • Default - If the command sets a configuration value or administrative state of the switch then any default settings (i.e. without issuing the command) of the configuration is shown here. • Command Mode - The mode in which the command can be issued. These modes are described in the section titled “Command Modes” below. • Command Default Level – The user privilege level in which the command can be issued. • Usage Guideline - If necessary, a detailed description of the command and its various utilization scenarios is given here. • Example(s) - Each command is accompanied by a practical example of the command being issued in a suitable scenario. Command Modes There are several command modes available in the command-line interface (CLI). The set of commands available to the user depends on both the mode the user is currently in and their privilege level. For each case, the user can see all the commands that are available in a particular command mode by entering a question mark (?) at the system prompt. The command-line interface has five pre-defined privilege levels: • Basic User - Privilege Level 1. This user account level has the lowest priority of the user accounts. The purpose of this type of user account level is for basic system checking. • Advanced User - Privilege Level 3. This user account level is allowed to configure the terminal control setting. This user account can only show limited information that is not related to security. • Power User - Privilege 8. This user account level can execute fewer commands than operator, including configuration commands other than the operator level and administrator level commands. • Operator - Privilege Level 12. This user account level is used to grant system configuration rights for users who need to change or monitor system configuration, except for security related information such as user accounts and SNMP account settings, etc.

8 • Administrator - Privilege Level 15. This administrator user account level can monitor all system information and change any of the system configuration settings expressed in this configuration guide. The command-line interface has a number of command modes. There are three basic command modes: • User EXEC Mode • Privileged EXEC Mode • Global Configuration Mode All other sub-configuration modes can be accessed via the Global Configuration Mode. When a user logs in to the switch, the privilege level of the user determines the command mode the user will enter after initially logging in. The user will either log into User EXEC Mode or the Privileged EXEC Mode. • Users with a basic user level will log into the switch in the User EXEC Mode. • Users with advanced user, power-user, operator or administrator level accounts will log into the switch in the Privileged EXEC Mode. Therefore, the User EXEC Mode can operate at a basic user level and the Privileged EXEC Mode can operate at the advanced user, power-user, operator, or administrator levels. The user can only enter the Global Configuration Mode from the Privileged EXEC Mode. The Global Configuration Mode can be accessed by users who have operator or administrator level user accounts. As for sub-configuration modes, a subset of those can only be accessed by users who have the highest secure administrator level privileges. The following table briefly lists the available command modes. Only the basic command modes and some of the sub-configuration modes are enumerated. The basic command modes and basic sub-configuration modes are further described in the following chapters. Descriptions for the rest of the sub-configuration modes are not provided in this section. For more information on the additional sub-configuration modes, the user should refer to the chapters relating to these functions. The available command modes and privilege levels are described below: Command Mode/ Privilege Level Purpose User EXEC Mode / Basic User level This level has the lowest priority of the user accounts. It is provided only to check basic system settings. Privileged EXEC Mode / Advanced User level This level is allowed to configure the terminal control setting. This user account can only show limited information that is not related to security. Privileged EXEC Mode / Power User level This level can execute less commands than operator, include the configure commands other than the operator level and administrator level commands. Privileged EXEC Mode / Operator level For changing both local and global terminal settings, monitoring, and performing certain system administration tasks. The system administration tasks that can be performed at this level except for any security related information. Privileged EXEC Mode / This level is identical to privileged EXEC mode at the operator level,

9 Administrator level except that a user at the administrator level can monitor and clear security related settings. Global Configuration Mode / Operator level For applying global settings, except for security related settings, on the entire switch. In addition to applying global settings on the entire switch, the user can access other sub-configuration modes from global configuration mode. Global Configuration Mode / Administrator level For applying global settings on the entire switch. In addition to applying global settings on the entire switch, the user can access other sub- configuration modes from global configuration mode. Interface Configuration Mode / Administrator level For applying interface related settings. VLAN Interface Configuration Mode For applying VLAN interface related settings. VLAN Configuration Mode For applying settings to a VLAN. IP Access-List Configuration Mode For specifying filtering criteria for an IP access list. User EXEC Mode at Basic User Level This command mode is mainly designed for checking basic system settings. This command mode can be entered by logging in as a basic user. Privileged EXEC Mode at Advanced User Level This command mode is mainly designed for checking basic system settings, allowing users to change the local terminal session settings and carrying out basic network connectivity verification. One limitation of this command mode is that it cannot be used to display information related to security. This command mode can be entered by logging in as an advanced user. Privileged EXEC Mode at Power User Level User logged into the switch in privileged EXEC mode at this level can execute fewer commands than operator, including the configuration commands other than the operator level and administrator level commands. The method to enter privileged EXEC mode at power user level is to login to the switch with a user account that has a privileged level of 8. Privileged EXEC Mode at Operator Level Users logged into the switch in privileged EXEC mode at this level can change both local and global terminal settings, monitor, and perform system administration tasks (except for security related information). The method to enter privileged EXEC mode at operator level is to login to the switch with a user account that has a privilege level of 12. Privileged EXEC Mode at Administrator Level This command mode has a privilege level of 15. Users logged in with this command mode can monitor all system information and change any system configuration settings mentioned in this Configuration Guide. The method to enter privileged EXEC mode at administrator level is to login to the switch with a user account that has a privilege level of 15. Global Configuration Mode The primary purpose of the global configuration mode is to apply global settings on the entire switch. Global configuration mode can be accessed at advanced user, power user, operator or administrator level user accounts. However, security related settings are not accessible at advanced user, power user or operator user accounts. In addition to applying global settings on the entire switch, the user can also access other sub-configuration modes. In order to access the global configuration mode, the user must be logged in with the corresponding account level and use the configure terminal command in the privileged EXEC mode.

10 In the following example, the user is logged in as an Administrator in the Privileged EXEC Mode and uses the configure terminal command to access the Global Configuration Mode: Switch# configure terminal Switch(config)# The exit command is used to exit the global configuration mode and return to the privileged EXEC mode. Switch(config)# exit Switch# The procedures to enter the different sub-configuration modes can be found in the related chapters in this Configuration Guide. The command modes are used to configure the individual functions. Interface Configuration Mode Interface configuration mode is used to configure the parameters for an interface or a range of interfaces. An interface can be a physical port, VLAN, or other virtual interface. Thus, interface configuration mode is distinguished further according to the type of interface. The command prompt for each type of interface is slightly different. VLAN Interface Configuration Mode VLAN interface configuration mode is one of the available interface modes and is used to configure the parameters of a VLAN interface. To access VLAN interface configuration mode, use the following command in global configuration mode: Switch(config)# interface vlan 1 Switch(config-if)# Creating a User Account By default, there is no user account created on this switch. For security reasons, it is highly recommended to create user accounts to manage and control access to this switch’s interface. This section will assist a user with creating a user account by means of the Command Line Interface. Observe the following example. Switch#enable Switch# configure terminal Switch(config)# username admin password admin Switch(config)# username admin privilege 15 Switch(config)# line console Switch(config-line)#login local Switch(config-line)# In the above example we had to navigate and access the username command. • Starting in the User EXEC Mode we enter the command enable to access the Privileged EXEC Mode. • After accessing the Privileged EXEC Mode, we entered the command configure terminal to access the Global Configuration Mode. The username command can be used in the Global Configuration Mode. • The command username admin password admin creates a user account with the username of admin and a password of admin. • The command username admin privilege 15 assigns a privilege level value of 15 to the user account admin.

11 • The command line console allows us to access the console interface’s Line Configuration Mode. • The command login local tell the switch that users need to enter locally configured login credentials to access the console interface. Save the running configuration to the start-up configuration. This means to save the changes made so that when the switch is rebooted, the configuration will not be lost. The following example shows how to save the running configuration to the start-up configuration. Switch#copy running-config startup-config Destination filename startup-config? [y/n]: y Saving all configurations to NV-RAM.......... Done. Switch# After the switch was rebooted, or when the users logs out and back in, the newly created username and password must be entered to access the CLI interface again, as seen below. DXS-3600-32S TenGigabit Ethernet Switch Command Line Interface Firmware: Build 2.00.012 Copyright(C) 2013 D-Link Corporation. All rights reserved. User Access Verification Username:admin Password:***** Switch# Interface Notation When configuration the physical ports available on this switch, a specific interface notation is used. The following will explain the layout, terminology and use of this notation. In the following example, we’ll enter the Global Configuration Mode and then enter the Interface Configuration Mode, using the notation 1/0/1. After entering the Interface Configuration Mode for port 1, we’ll change the speed to 1 Gbps, using the speed 1000 command. Switch# configure terminal Switch(config)# interface Ethernet 1/0/1 Switch(config-if)# speed 1000 Switch(config-if)# In the above example the notation 1/0/1 was used. The terminology for each parameter is as follows: • Interface Unit’s ID / Open Slot’s ID / Port’s ID

12 The Interface Unit’s ID is the ID of the stacking unit without the physical stack. If stacking is disabled or this unit is a stand-alone unit, then this parameter is irrelevant. The Open Slot’s ID is the ID of the module plugged into the open module slot of the switch. The DXS-3600 Series switch doesn’t support any open modules slots, thus this parameters will always by zero for this switch series. Lastly, the Port’s ID is the physical port number of the port being configured. In summary the above example will configure the stacked switch with the ID of 1, with the open slot ID of 0, and the physical port number 1. Error Messages When the users issue a command that the switch does not recognize, error messages will be generated to assist users with basic information about the mistake that was made. A list of possible error messages are found in the table below. Error Message Meaning Ambiguous command Not enough keywords were entered for the switch to recognize the command. Incomplete command The command was not entered with all the required keyword. Invalid input detected at ^marker The command was entered incorrectly. The following example shows how an ambiguous command error message is generated. Switch# show v Ambiguous command Switch# The following example shows how an incomplete command error message is generated. Switch# show Incomplete command Switch# The following example shows how an invalid input error message is generated. Switch# show verb ^ Invalid input detected at ^marker Switch# Editing Features The command line interface of this switch supports to following keyboard keystroke editing features. Keystroke Description Delete Deletes the character under the cursor and shifts the remainder of the line to the left. Backspace Deletes the character to the left of the cursor and shifts the remainder of the line to the left.

13 Left Arrow Moves the cursor to the left. Right Arrow Moves the cursor to the right. CTRL+R Toggles the insert text function on and off. When on, text can be inserted in the line and the remainder of the text will be shifted to the right. When off, text can be inserted in the line and old text will automatically be replaced with the new text. Return Scrolls down to display the next line or used to issue a command. Space Scrolls down to display the next page. ESC Escapes from the displaying page. Display Result Output Modifiers Results displayed by show commands can be filtered using the following parameters: • begin FILTER-STRING - This parameter is used to start the display with the first line that matches the filter string. • include FILTER-STRING - This parameter is used to display all the lines that match the filter string. • exclude FILTER-STRING - This parameter is used to exclude the lines that match the filter string from the display. The example below shows how to use the begin FILTER-STRING parameter in a show command. Switch#show running-config | begin # DEVICE # DEVICE configure terminal end # AAA configure terminal # AAA START no aaa new-model # AAA END end Switch# The example below shows how to use the include FILTER-STRING parameter in a show command. Switch#show running-config | include # DEVICE # DEVICE Switch# The example below shows how to use the exclude FILTER-STRING parameter in a show command. Switch#show running-config | exclude # DEVICE Building configuration... Current configuration : 56102 bytes

15 2. Basic CLI Commands 2-1 help This command is used to display a brief description of the help system. Use the help command in any command mode. help Parameters None. Default None. Command Mode User EXEC or Any Configuration Mode. Command Default Level Level: 1. Usage Guideline The help command provides a brief description for the help system, which includes the following functions: • To list all commands available for a particular command mode, enter a question mark (?) at the system prompt. • To obtain a list of commands that begin with a particular character string, enter the abbreviated command entry immediately followed by a question mark (?). This form of help is called word help, because it lists only the keywords or arguments that begin with the abbreviation entered. • To list the keywords and arguments associated with a command, enter a question mark (?) in place of a keyword or argument on the command line. This form of help is called the command syntax help, because it lists the keywords or arguments that apply based on the command, keywords, and arguments already entered. Example This example shows how the help command is used to display a brief description of the help system. Switch# help The switch CLI provides advanced help feature. 1. Help is available when you are ready to enter a command argument (e.g. 'show ?') and want to know each possible argument. 2. Helpis provided when an abbreviated argument is entered and you want to know what arguments match the input(e.g. 'show ve?'.). If nothing matches, the help list will be empty and you must backup until entering a '?' shows the available options. 3. For completing a partial command name could enter the abbreviated command name immediately followed by a key. Note: Since the character ’#’ is used for help purpose, to enter the character '?' in a string argument, press ctrl+v immediately followed by the character '?'. Switch#

16 The following example shows how to use the word help to display all the Privileged EXEC Mode commands that begin with the letters “re”. The letters entered before the question mark (?) are reprinted on the next command line to allow the user to continue entering the command. Switch# re? reboot reconfig rename Switch# re The following example shows how to use the command syntax help to display the next argument of a partially complete IP access-list standard command. The characters entered before the question mark (?) is reprinted on the next command line to allow the user to continue entering the command. Switch# ip access-list standard ? <1-1999> Standard IP access-list number WORD Access-list name Switch# ip access-list standard 2-2 enable This command is used to enter the Privileged EXEC Mode. enable [PRIVILEGE-LEVEL] Parameters PRIVILEGE-LEVEL (Optional) Specifies to set the privilege level for the user. The privilege level is between 1 and 15. If not specified, level 15 will be used. Default None. Command Mode User EXEC Mode. Privilege EXEC Mode. Command Default Level Level: 1. Usage Guideline Execute this command if the current level is lower than the command level. If the privileged level requires a password, enter it in the field provided. However, only three attempts are allowed. Failure to access this level returns the user to the current level. Example This example shows how to enter the Privileged EXEC Mode. Switch# enable 15 password:***

17 Switch# 2-3 disable This command is used to downgrade to a level lower user level than the privileged level. disable [PRIVILEGE-LEVEL] Parameters PRIVILEGE LEVEL Specifies the privilege level to enter. If not specified, level 1 is used. Default None. Command Mode User EXEC Mode. Privilege EXEC Mode. Command Default Level Level: 1. Usage Guideline Use this command to enter the privilege level, which is lower than the current level. When using this command to enter the privilege level, that has a password configured, no password is needed. Example This example shows how to logout. Switch# disable Switch# logout 2-4 configure terminal This command is used to enter the Global Configuration Mode. configure terminal Parameters None. Default None Command Mode Privilege EXEC Mode. Command Default Level Level: 12.

18 Usage Guideline This command is used to enter the Global Configuration Mode. Example This example shows how to enter into Global Configuration Mode. Switch# configure terminal Switch(config)# 2-5 login (EXEC) This command is used to configure a login username. login Parameters None. Default None. Command Mode User EXEC Mode. Privileged EXEC Mode. Command Default Level Level: 1. Usage Guideline Use this command to change the login account. Three attempts are allowed to login to the switch’s interface. When using Telnet, if all attempts fail, access will return to the command prompt. If no information is entered within 60 seconds, the session will return to the state when logged out. Example This example shows how to login with username “user1”. Switch# login Username: user1 Password: xxxxx Switch# 2-6 login (Line) This command is used to set the line login method. Use the no form of the command to disable the login. login [local] no login

19 Parameters login Specifies that the line login method will be login. local Specifies that the line login method will be local. Default By default, there is no login details configured for the console line. By default, there is a login method (by password) configured for the Telnet line. By default, there is a login local method (by username and password) configured for the SSH line. Command Mode Line Configuration Mode. Command Default Level Level: 15. Usage Guideline For Console and Telnet access, when AAA is enabled, the line uses rules configured by the AAA module. When AAA is disabled, the line uses the following authentication rules: • When login is disabled, the user can enter the line at Level 1. • When the by password option is selected, after inputting the same password as the command password, the user enter the line at level 1. If the password wasn’t previously configured an error message will be displayed and the session will be closed. • When the username and password option is selected, enter the username and password configured by the username command. For SSH access, there are three authentication types: • SSH public key, • Host-based authentication, and • Password authentication. The SSH public key and host-based authentication types are independent from the login command in the line mode. If the authentication type is password, the following rules apply: • When AAA is enabled, the AAA module is used. • When AAA is disabled, the following rules are used: o When login is disabled, the username and password is ignored. Enter the details at Level 1. o When the username and password option is selected, use the username and password setup by the username command. o When the password option is selected, the username is ignored but a password is required using the password command to enter the line at level 1. Example This example shows how to enter the Line Configuration Mode and to create a password for the line user. This password only takes effect once the corresponding line is set to login. Switch# configure terminal Switch(config)# line console Switch(config-line)# password loginpassword Switch(config-line)# This example shows how to configure the line console login method as “login”.

Use the password recovery command in the reset configuration mode. password-recovery Parameters None. Default None. Command Mode Reset Configuration Mode. Command Default Level Level: 15. Usage Guideline Under certain circumstances, the administrator may have the need to update a user’s account because the password of the account was forgotten. To do this, the administrator has to enter the Reset Configuration Mode. For assistance on how to enter the reset configuration mode, please contact the technical support personnel. After entering the reset configuration mode, use the password-recovery command and follow the confirmation prompt message to recover the password related settings. Password recovery basically does the following three things: • Update an existing user account by entering the username of an existing user and its new password or add a new user account with a privileged level of 15. The new user account cannot be created if the maximum number of user accounts is exceeded. • Update the enabled password for the administrator-privileged level. • Disable the AAA function to let the system do local authentication. The updated setting will be saved in the running configuration file. Before the reload is executed, the switch will prompt the administrator to approve saving the running configuration as the startup configuration.

STARTING-SEQUENCE- NUMBER Specifies that the access list entries will be re-sequenced using this initial value. The default value is 10. The range of possible sequence numbers is 1 through 65535. INCREMENT Specifies the number that the sequence numbers step. The default value is 10. For example, if the increment (step) value is 5 and the beginning sequence number is 20, the subsequent sequence numbers are 25, 30, 35, 40, and so on. The range of valid values is from 1 to 32. Default The default start sequence number is 10. The default increment is 10. Command Mode Global Configuration Mode. Command Default Level Level: 12. Usage Guideline This feature allows the user to re-sequence the entries of a specified access list with an initial sequence number determined by the STARTING-SEQUENCE-NUMBER parameter and continuing in the increments determined by the INCREMENT parameter. If the highest sequence number exceeds the maximum possible sequence number, then there will be no re-sequencing. If a rule entry is created without specifying the sequence number, the sequence number will be automatically assigned. If it is the first entry, a start sequence number is assigned. Subsequent rule entries are assigned a sequence number that is increment value greater than the largest sequence number in that access list and the entry is placed at the end of the list. After the start sequence number or increment change, the sequence number of all previous rules (include the rules that assigned sequence by user) will change according to the new sequence setting. Example This example shows how to re-sequence the sequence number of an IP access-list, named R&D. Switch# configure terminal Switch(config)# show access-list ip R&D Extended IP access list R&D(ID: 3552) 10 permit tcp any 10.20.0.0 255.255.0.0

Use the no form of the command to disable the ACL hardware counter function. acl-hardware-counter {access-group {ACCESS-LIST-NAME | ACCESS-LIST-NUMBER} | vlan- filter ACCESS-MAP-NAME} no acl-hardware-counter {access-group {ACCESS-LIST-NAME | ACCESS-LIST-NUMBER} | vlan- filter ACCESS-MAP-NAME} Parameters access-group ACCESS-LIST- NAME Specifies the name of the access list to be configured. access-group ACCESS-LIST- NUMBER Specifies the number of the access list to be configured. vlan-filter ACCESS-MAP- NAME Specifies the name of the access map to be configured. Default By default, this option is disabled. Command Mode Global Configuration Mode. Command Default Level Level: 12. Usage Guideline

44 The command with parameter access-group will enable the ACL hardware counter for all ports that have applied the specified access-list name or number. The number of packets, that match each rule, are counted. The command with parameter vlan-filter will enable the ACL hardware counter for all VLAN(s) that have applied the specified VLAN access-map. The number of packets that permitted by each access map are counted. Example This example shows how to enable the ACL hardware counter. Switch# configure terminal Switch(config)# acl-hardware-counter access-group abc Switch(config)# 4-3 action This command is used to configure the forward, drop, or redirect action of the sub-map in the VLAN access-map sub-map configuration mode. Use the no command to reset to the default action. action {forward | drop | redirect INTERFACE-ID} no action Parameters forward Specifies to forward the packet when matched. drop Specifies to drop the packet when matched. redirect INTERFACE-ID Specifies the interface ID for the redirection action. Only physical ports are allowed to be specified. Default By default, the action is forward. Command Mode VLAN Access-map Sub-map Configuration Mode. Command Default Level Level: 12. Usage Guideline One sub-map has only one action. The action configured later overwrites the previous action. A VLAN access map can contain multiple sub-maps. The packet that matches a sub-map (a packet permitted by the associated access-list) will take the action specified for the sub-map. No further checking against the next sub-maps is done. If the packet does not match a sub-map, then the next sub-map will be checked. Example This example shows how to configure the action in the sub-map. Switch# show vlan access-map VLAN access-map vlan-map 20 match mac address: ext_mac(ID: 6856) action: forward Switch# configure terminal

Usage Guideline If an IP access group is already configured on the interface, the command applied later will overwrite the previous setting. Only one access list of the same type can be applied to the same interface; but access- lists of different types can be applied to the same interface. The association of an access group with an interface will consume the filtering entry resource in the switch controller. If the resources are insufficient to commit the command, then an error message will be displayed. There is a limitation on the number of port operator resources. If applying the command exhausts the available port selectors, then an error message will be displayed. Example This example shows how to specify the IP access list “Strict-Control” as an IP access group for an Ethernet port 6/0/2. Switch# configure terminal Switch(config)# interface eth6/0/2 Switch(config-if-gi)#ip access-group Strict-Control The remaining applicable IP related access entries are 2500 The remaining applicable port operators are 10 Switch(config-if-gi)# 4-8 ip access-list This command is used to create or modify an IP access list.

Example This example shows how to configure an extended IP access list, named “Strict-Control” and an IP access-list, named “pim-srcfilter”. Switch# configure terminal Switch(config)# ip access-list extended Strict-Control Swtich(config-ip-ext-acl)# permit tcp any 10.20.0.0 255.255.0.0 Swtich(config-ip-ext-acl)# exit Swtich(config)# ip access-list pim-srcfilter Switch(config-ip-acl)# permit host 172.16.65.193 any Switch(config-ip-acl)# 4-9 ipv6 access-group This command is used to specify the IPv6 access list to be applied to an interface. Use the no command to remove an IPv6 access list. ipv6 access-group {NAME | NUMBER} [in | out] no ipv6 access-group [NAME | NUMBER] [in | out] Parameters NAME Specifies the name of the IPv6 access list to be applied. NUMBER Specifies the number of the IPv6 access list to be applied. in Specifies that the IPv6 access list will be applied to check in the ingress direction. If the direction is not specified, in is used. out Specifies that the IPv6 access list will be applied to check in the egress direction. Default None. Command Mode Interface Configuration Mode. Command Default Level Level: 12. Usage Guideline

50 Only one access list of the same type can be applied to the same interface; but access lists of different types can be applied to the same interface. The association of an access group with an interface will consume the filtering entry resource in the switch controller. If the resource is insufficient to commit the command, then an error message will be displayed. There is a limitation on the number of port operator resources. If applying the command exhausts the available port selectors, then an error message will be displayed. Example This example shows how to specify the IPv6 access list “ip6-control” as an IP access group for eth3/0/3. Switch# configure terminal Switch(config)# interface eth3/0/3 Switch(config-if)# ipv6 access-group ip6-control in The remaining applicable IPv6 related access entries are 2500 The remaining applicable port operators are 10 Switch(config-if)# 4-10 ipv6 access-list This command is used to create or modify an IPv6 access list.

Default None. Command Mode Extended Expert Access-list Configuration Mode. Command Default Level Level: 12. Usage Guideline If a rule entry is created without a sequence number, a sequence number will be automatically assigned. If it is the first entry, the sequence number 10 is assigned. A subsequent rule entry will be assigned a sequence number that is 10 greater than the largest sequence number in that access list and is placed at the end of the list. The user can use the command access-list sequence to change the start sequence number and increment number for the specified access list. After the command is applied, the new rule without specified sequence number will be assigned sequence based new sequence setting of the specified access list. When you manually assign the sequence number, it is better to have a reserved interval for future lower sequence number entries. Otherwise, it will create extra effort to insert an entry with a lower sequence number. The sequence number must be unique in the domain of an access-list. If you enter a sequence number that is already present, an error message will be shown. Even if the fragment parameter of the tcp, udp and icmp parameters of the permit | deny (expert access-list) command is removed, the user can still use the PROTOCOL option of the permit | deny (expert access-list) command to configure the fragment parameter. Example This example shows how to use the extended expert ACL. The purpose is to deny all the TCP packets with the source IP address 192.168.4.12 and the source MAC address 00:13:00:49:82:72.

Default None. Command Mode IP Access-list Configuration Mode. Command Default Level Level: 12. Usage Guideline If a rule entry is created without a sequence number, a sequence number will be automatically assigned. If it is the first entry, the sequence number 10 is assigned. A subsequent rule entry will be assigned a

61 sequence number that is 10 greater than the largest sequence number in that access list and is placed at the end of the list. The user can use the command access-list sequence to change the start sequence number and increment number for the specified access list. After the command is applied, the new rule without specified sequence number will be assigned sequence based new sequence setting of the specified access list. When you manually assign the sequence number, it is better to have a reserved interval for future lower sequence number entries. Otherwise, it will create extra effort to insert an entry with a lower sequence number. The sequence number must be unique in the domain of an access-list. If you enter a sequence number that is already present, an error message will be shown. To create a matching rule for an IP standard access list, only the source IP address or destination IP address fields can be specified. Example This example shows how to create four entries for an IP extended access list, named Strict-Control.

70 Default None. Command Mode Global Configuration Mode. Command Default Level Level: 12. Usage Guideline A VLAN access map can contain multiple sub-maps. For each sub-map, one access list (IP access list, IPv6 access list or MAC access list) can be specified and one action can be specified. After a VLAN access map is created, the user can use the vlan filter command to apply the access map to VLAN(s). A sequence number will be assigned automatically if the user does not assign it manually, and the automatically assigned sequence number starts from 10, and increase 10 per new entry. The packet that matches the sub-map (that is packet permitted by the associated access-list) will take the action specified for the sub-map. No further check against the next sub-maps is done. If the packet does not match a sub-map, then the next sub-map will be checked. Using the no form of this command without specify sequence numbers, will delete all sub-map information of the specified access-map. Example This example shows how to create a VLAN access map. Switch# configure terminal Switch(config)# vlan access-map vlan-map 20 Switch(config-access-map)# 4-26 vlan filter This command is used to apply a VLAN access map in a VLAN. Use the no command to remove a VLAN access map from the VLAN. vlan filter MAP-NAME vlan-list VLAN-ID-LIST no vlan filter MAP-NAME vlan-list VLAN-ID-LIST Parameters MAP-NAME Specifies the name of the VLAN access map. VLAN-ID-LIST Specifies the VLAN ID list. Default None. Command Mode Global Configuration Mode. Command Default Level Level: 12. Usage Guideline

71 A VLAN can only be associated with one VLAN access map. Example This example shows how to apply the VLAN access-map “vlan-map” in VLAN 5. Switch# configure terminal Switch(config)# vlan filter vlan-map vlan-list 5 Switch(config-access-map)# end Switch# show vlan filter VLAN Map vlan-map Configured on VLANs: 5 Switch#

72 5. Access Management Commands 5-1 access class This command is used to specify an access list to restrict the access via a line. Use the no form of the command to remove the specified access list check. access-class IP-ACL no access-class IP-ACL Parameters IP-ACL Specifies a standard IP access list. The source address field of the permit or deny entry define the valid or invalid host. Default None. Command Mode Line Configuration Mode. Command Default Level Level: 15. Usage Guideline This command specifies access lists to restrict the access via a line. At most two access lists can be applied to a line. If two access lists are already applied, an attempt to apply a new access list will be rejected until an applied access list is removed by the no form of this command. Example This example shows how a standard IP access list is created and is specified as the access list to restrict access via Telnet. Only the host 226.1.1.1 is allowed to access the server. Switch# configure terminal Switch(config)# ip access-list vty-filter Switch(config-ip-acl)# permit 226.1.1.1 0.0.0.0 Switch(config-ip-acl)# exit Switch(config)# line telnet Switch(config-line)# access-class vty-filter Switch(config-line)# 5-2 banner login This command is used to enter banner login mode to configure the banner login message. Use the no command to revert to the factory default the login banner. banner login cMESSAGEc no banner login

73 Parameters c Specifies the separator of the login banner message, for example a pound sign (#). The delimiting character is not allowed in the login banner message. MESSAGE Specifies the contents of a login banner which will be displayed before the username and password login prompts. Default None. Command Mode Global Configuration Mode. Command Default Level Level: 12. Usage Guideline Use this command to define a customized banner to be displayed after the user successfully logs into the system. Follow the banner login command with one or more blank spaces and a delimiting character of your choice. Then enter one or more lines of text, terminating the message with the second occurrence of the delimiting character. For example with a pound sign (#) being the delimiting character, after inputting the delimiting character, press the enter key, then the login banner contents can be typed. The delimiting character need to be input then press enter to complete the type. To configure the login banner contents to default, use no banner login command in global configuration mode. Note: The typed additional characters after the end delimiting character are invalid. These characters will be discarded by the system. The delimiting character cannot be used in the login banner text. Example This example shows how to configure a login banner. The hash sign (#) is used as the delimiting character. The start delimiting character, banner contents and end delimiting character will be input before press first enter key: Switch# configure terminal Switch(config)# banner login #Enter Command Line Interface# Switch(config)# This example shows how to configure a login banner.

The no command will disable the encryption. service password-encryption no service password-encryption Parameters None. Default By default, this option is disabled. Command Mode Global Configuration Mode. Command Default Level Level:15. Usage Guideline The user account configuration information is stored in the running configuration file and can be applied to the system later. If the service password-encryption command is enabled, the password will be stored in the encrypted form. When the service password encryption option is disabled and the password is specified in the plain text form, the password will be in plain text form. However, if the password is specified in the encrypted form or if the password has been converted to the encrypted form by the last enable password encryption command, the password will still be in the encrypted form. It cannot be reverted back to plain text.

82 The password affected by this command includes the user account password, enable password, and the authentication password. Example This example shows how to enable the encryption of the password before stored in the configuration file. Switch# configure terminal Switch(config)# service password encryption Switch(config)# 5-15 show terminal This command is used to obtain information about the terminal configuration parameter settings for the current terminal line. Use this command in any EXEC mode or any configuration mode. show terminal Parameters None. Default None. Command Mode User EXEC or Any Configuration Mode. Command Default Level Level: 1.

The “well-known” TCP port for the Telnet protocol is 23 Default None. Command Mode EXEC Mode.

84 Command Default Level Level: 1. Usage Guideline This is the Telnet client function and can be used to communicate with another device using the Telnet feature. The Telnet software supports special Telnet commands in the form of Telnet sequences that map generic terminal control functions to operating system-specific functions. To issue a special Telnet command, enter the escape sequence and then a command character. The default escape sequence is CTRL+_ (press and hold the CTRL and Shift keys and the underscore ‘_’ key). The special Telnet commands will be displayed as follows: • e – Exits the Telnet connection. Either an uppercase or lowercase letter ‘e’ can exit the Telnet connection. If another key is pressed, the terminal will return to the original active Telnet session. Multiple Telnet sessions can be opened on the switch system and each open Telnet session can have its own Telnet client software supported at the same time Example This example shows how to Telnet to the IP address 10.90.90.91 using the default port 23. The IP address, 10.90.90.91 is the DXS-3600-32S management interface which allows a user to login. Switch# telnet 10.90.90.91 DXS-3600-32S Gigabit Ethernet Switch Command Line Interface Firmware: Build 2.00.012 Copyright(C) 2013 D-Link Corporation. All rights reserved. Password required, but none set Switch# This example shows how to Telnet through port 23 to 10.90.90.91 and the connection failed. Try using port 3500 instead to login into the management interface. Switch#telnet 10.90.90.91 ERROR: Could not open a connection to host on server port 23.

Password required, but none set Switch# 5-18 terminal length

85 The command is used to configure the number of lines displayed on the screen. The terminal length command will only affect the current session. The default terminal length command will set the default value but it doesn’t affect the current session. The newly created, saved session terminal length will use the default value. Use no form of this command to revert back to the default settings. terminal length default NUMBER no terminal length default Parameters NUMBER Specifies the number of lines to display on the screen. This value must be between 0 and 512.When the terminal length is 0, the display will not stop until it reaches the end of the display. Default By default, this value is 24. Command Mode Use the EXEC Mode or Privilege EXEC Mode for the terminal length command. Use the Global Configuration Mode for the terminal length default command. Command Default Level Level: 1 (for the terminal length command). Level: 12 (for the terminal length default command). Usage Guideline When the terminal length is 0, the display will not stop until it reaches the end of the display. If the terminal length is specified to a value other than 0, for example 50, then the display will stop after every 50 lines. The terminal length is used to set the number of lines displayed on the current terminal screen. This command also applies to Telnet and SSH sessions. Valid entries are from 0 to 512. The default is 24 lines. A selection of 0's instructs the Switch to scroll continuously (no pausing). Output from a single command that overflows a single display screen is followed by the --More-- prompt. At the --More-- prompt, press CTRL+C, q, Q, or ESC to interrupt the output and return to the prompt. Press the Spacebar to display an additional screen of output, or press Return to display one more line of output. Setting the screen length to 0 turns off the scrolling feature and causes the entire output to display at once. Unless the default keyword is used, a change to the terminal length value applies only to the current session. When using the no form of this command, the number of lines in the terminal display screen is reset to 24. The terminal length default command is available in the global configuration mode. The command setting does not affect the current existing terminal sessions but affects the new terminal sessions that are activated later. Only the default terminal length value can be saved. Example This example shows how to change the lines to be displayed on a screen to 60. Switch# terminal length 60 Switch# 5-19 terminal speed This command is used to setup the terminal speed. Use the no form of the command to reset to the default setting.

86 terminal speed BPS no terminal speed Parameters BPS Specifies the console rate in bits per second (bps). Default By default, this value is 115200. Command Mode Global Configuration Mode. Command Default Level Level: 12. Usage Guideline Use this command to configure the terminal connection speed. Some baud rates available on the devices connected to the port might not be supported on the switch. Example This example shows how to configure the serial port baud rate to 9600 bps. Switch# configure terminal Switch(config)# terminal speed 9600 Switch(config)# 5-20 session timeout This command is used to configure the line session timeout value. Use the no form of the command to reset it to the default settings. session-timeout MINUTES no session-timeout Parameters MINUTES Specifies the timeout length in minutes. 0 represents never timeout. Default By default, this value is 3 minutes. Command Mode Line Configuration Mode. Command Default Level Level: 12. Usage Guideline This timer specifies the timeout for auto-logout sessions established by the line that is being configured.

87 Example This example shows how to configure the console session to never timeout. Switch# configure terminal Switch(config)# line console Switch(config-line)# session-timeout 0 Switch(config-line)# 5-21 terminal width The command is used to set the number of character columns on the terminal screen for the current session line. The terminal width command will only affect the current session. The terminal width default command will set the default value, but it doesn’t affect any current sessions. terminal width default NUMBER no terminal width default Parameters NUMBER Specifies the number of characters to display on the screen. Valid values are from 40 to 255. Default By default, this value is 80 characters. Command Mode Use the EXEC Mode or Privilege EXEC Mode for the terminal width command. Use the Global Configuration Mode for the terminal width default command. Command Default Level Level: 1 (for the terminal width command). Level: 12 (for the terminal width default command). Usage Guideline By default, the switch’s system terminal provides a screen display width of 80 characters. The terminal width command changes the terminal width value which applies only to the current session. When changing the value in a session, the value applies only to that session. When the no form of this command is used, the number of lines in the terminal display screen is reset to the default, which is 80 characters. The terminal width default command is available in the global configuration mode. The command setting does not affect the current existing terminal sessions but affect the new terminal sessions that are activated later and just the global terminal width value can be saved. However, for remote CLI session access such as Telnet, the auto-negotiation terminal width result will take precedence over the default setting if the negotiation is successful. Otherwise, the default settings take effect. Example This example shows how to adjust the current session terminal width to 120 characters. Switch# show terminal Length: 24 lines

88 Width: 80 columns Default Length: 24 lines Default Width: 80 columns Baud rate: 9600 Switch# terminal width 120 Switch# show terminal Length: 24 lines Width: 120 columns Default Length: 24 lines Default Width: 80 columns Baud rate: 9600 Switch # 5-22 username This command is used to create a user account. Use the no command to delete the user account. username NAME [privilege LEVEL] [nopassword | password [0 | 7 ] PASSWORD] no username [NAME] Parameters NAME Specifies the user name with a maximum of 32 characters. privilege LEVEL Specifies the privilege level for each user. The privilege level must be between 1 and 15. nopassword Specifies that there will be no password associated with this account. password Specifies the password for the user. 0 Specifies the password in clear, plain text. The password length is between 1 and 32 characters and can contain embedded spaces. It is case-sensitive. If the password syntax cannot be specified, the syntax remains plain text. 7 Specifies the encrypted password based on SHA-1. The password length is fixed at 35 bytes. It is case-sensitive. The password is encrypted. If the password syntax is not specified, the syntax is plain text. PASSWORD Specifies the password string based on the type. Default By default, no username-based authentication system is established. If not specified, use 1. Command Mode Global Configuration Mode. Command Default Level Level: 15.

89 Usage Guideline This command creates user accounts with different access levels. When the user login with Level 1, the user will be in the User EXEC Mode. The user needs to further use the enable command to enter the Privileged EXEC Mode. When the user login with a Level higher than or equal to 2, the user will directly enter the Privileged EXEC Mode. Therefore, the Privileged EXEC Mode can be in Levels 2 to 15. The user can specify the password in the encrypted form or in the plain-text form. If it is in the plain-text form, but the service password encryption is enabled, then the password will be converted to the encrypted form. If the no username command is used without the user name specified, all users are removed. By default, the user account is empty. When the user account is empty, the user will be directly in the User EXEC Mode at Level 1. The user can further enter the Privileged EXEC Mode using the enable command. Example This example shows how to create an administrative username, called admin, and a password, called “mypassword”. Switch# configure terminal Switch(config)# username admin privilege 15 password 0 mypassword Switch(config)# This example shows how to remove the user account with the username admin. Switch# configure terminal Switch(config)# no username admin Switch(config)# 5-23 password This command is used to create a new password. Use the no form of the command to remove the password. password [0 | 7 ] PASSWORD no password Parameters 0 Specifies the password in clear, plain text. The password length is between 1 and 32 characters and can contain embedded spaces. It is case-sensitive. If the password syntax cannot be specified, the syntax remains plain text. 7 Specifies the encrypted password based on SHA-1. The password length is fixed at 35 bytes. It is case-sensitive. The password is encrypted. If the password syntax is not specified, the syntax is plain text. PASSWORD Specifies the password for the user. Default None.

90 Command Mode Line Configuration Mode. Command Default Level Level: 15. Usage Guideline This command is used to create a new user password. Only one password can be used for each type of line. Example This example shows how to create a password for the console line. Switch# configure terminal Switch(config)# line console Switch(config-line)# password 123 Switch(config-line)#

91 6. ARP Spoofing Prevention Commands 6-1 ip arp spoofing-prevention This command is used to configure an ARP Spoofing Prevention (ASP) entry of the gateway used for preventing ARP poisoning attacks. Use the no form of the command to delete an ARP spoofing prevention entry. ip arp spoofing-prevention GATEWAY-IP GATEWAY-MAC interface INTERFACE-ID [,|-] no ip arp spoofing-prevention GATEWAY-IP [interface INTERFACE-ID [,|-] ] Parameters GATEWAY-IP Specifies the IP address of the gateway. GATEWAY-MAC Specifies the MAC address of the gateway. The MAC address setting will replace the last configuration for the same gateway IP address. INTERFACE-ID Specifies the interface that will be activated or removed from active interface list (in the no form of this command). An ARP entry won't be checked, if the receiving port is not included in the specified interface list. , (Optional) Specifies a number of interfaces or separate a range of interfaces from a previous range. No space before and after the comma. - (Optional) Specifies a range of interfaces. No space before and after the hyphen. Default By default, no entries exist. Command Mode Global Configuration Mode. Command Default Level Level: 12. Usage Guideline This command is used to configure the ARP spoofing prevention (ASP) entry to prevent spoofing of the MAC address of the protected gateway. When an entry is created, ARP packets whose sender IP address matches the gateway IP address, of an entry, but its sender MAC address field does not match the gateway MAC address, of the entry, will be dropped by the system. The ASP will bypass the ARP packets whose sender IP address doesn’t match the configured gateway IP address. If an ARP address matches a configured gateway’s IP address, MAC address, and port list, then bypass the Dynamic ARP Inspection (DAI) check no matter if the receiving port is ARP ‘trusted’ or ‘untrusted’. Only physical ports and port channel interfaces are valid interface to be specified. Example This example shows how to configure an ARP spoofing prevention entry with an IP address of 10.254.254.251 and MAC address of 00-00-00-11-11-11 and activate the entry at port eth2/0/10 and port channel 3.

The following are keywords that can be used to specify a method. enable – Specifies to use the local enable password for authentication. group radius – Specifies to use the servers defined by the RADIUS server host command. group tacacs+ - Specifies to use the servers defined by the TACACS+ server host command. group GROUP-NAME – Specifies to use the server groups defined by the AAA group server command. none - Normally, the method is listed as the last method. The user will pass the authentication if it is not denied by previous method authentication. Default No AAA authentication method is configured. Command Mode Global Configuration Mode. Command Default Level Level: 15. Usage Guideline Use this command to configure the default authentication method list for determining access to the privileged EXEC level when users issue the enable [privilege LEVEL] command. The authentication with the RADIUS server will be based on the privilege level and take either “enable12” or “enable15” as the user name. Example This example shows how to set the default method list for authenticating. The method tries the server group “group2”. Switch#configure terminal Switch(config)# aaa authentication enable default group group2 7-6 aaa authentication dot1x This command is used to configure the default method list used for 802.1X authentication. Use the no command to remove the default method list. aaa authentication dot1x default METHOD1 [METHOD2...] no aaa authentication dot1x default Parameters METHOD1 [METHOD2...] Specifies the list of methods that the authentication algorithm tries in the given sequence. Enter at least one method or enter up to four methods. The following are keywords that can be used to specify a method. local – Specifies to use the local database for authentication. group radius – Specifies to use the servers defined by the RADIUS server host command.

98 group GROUP-NAME – Specifies to use the server groups defined by the AAA group server. none - Normally, the method is listed as the last method. The user will pass authentication if it is not denied by previous method authentication. Default No AAA authentication method is configured. Command Mode Global Configuration Mode. Command Default Level Level: 15. Usage Guideline Use this command to configure the default authentication method list for 802.1X authentication. Initially, the default method list is not configured. The authentication of 802.1X requests will be performed based on the local database. Example This example shows how to set the default methods list for authenticating dot1X users. Switch#configure terminal Switch(config)# aaa authentication dot1x default group radius 7-7 aaa authentication login This command is used to configure the method list used for login authentication. Use the no command to remove a login method list. aaa authentication login {default | LIST-NAME} METHOD1 [METHOD2...] no aaa authentication login {default | LIST-NAME} Parameters default Specifies to configure the default method list for login authentication. LIST-NAME Specifies the name of the method list other than the default method list. This name can be up to 32 characters long. METHOD1 [METHOD2...] Specifies the list of methods that the authentication algorithm tries in the given sequence. Enter at least one method or enter up to four methods. The following are keywords that can be used to specify a method. local – Specifies to use the local database for authentication. group radius – Specifies to use the servers defined by the RADIUS server host command. group tacacs+ - Specifies to use the servers defined by the TACACS+ server host command. group GROUP-NAME – Specifies to use the server groups defined by the AAA group server command. none - Normally, the method is listed as the last method. The user will

99 pass authentication if it is not denied by previous method’s authentication. Default No AAA authentication method list is configured. Command Mode Global Configuration Mode. Command Default Level Level: 15. Usage Guideline Use this command to configure the authentication method list used for login authentication. Multiple method lists can be configured. The default keyword is used to define the default method list. If authentication uses the default method list but the default method list does not exist, then the authentication will be performed via the local database. The login authentication authenticates the login user name and password, and also assigns the privilege level to the user based on the database. A method list is a sequential list describing the authentication methods to be queried in order to authenticate a user. Method lists enable you to designate one or more security protocols to be used for authentication, thus ensuring a backup system for authentication in case the initial method fails. The switch system uses the first listed method to authenticate users. If that method fails to respond, the switch system selects the next authentication method listed in the method list. This process continues until there is successful communication with a listed authentication method or all methods defined in the method list are exhausted. It is important to note that the switch system attempts authentication with the next listed authentication method only when there is no response from the previous method. If authentication fails at any point in this cycle, meaning that the security server or local username database responds by denying the user access, the authentication process stops and no other authentication methods are attempted. Example This example shows how to set the default login methods list for authenticating of login attempts. Switch#configure terminal Switch(config)# aaa authentication login default group group2 local 7-8 aaa authentication mac-auth This command is used to configure the default method list used for MAC authentication. Use the no command to remove the default method list. aaa authentication mac-auth default METHOD1 [METHOD2...] no aaa authentication mac-auth default Parameters METHOD1 [METHOD2...] Specifies the list of methods that the authentication algorithm tries in the given sequence. Enter at least one method or enter up to four methods. The following are keywords that can be used to specify a method. local – Specifies to use the local database for authentication.

100 group radius – Specifies to use the servers defined by the RADIUS server host command. group GROUP-NAME – Specifies to use the server groups defined by the AAA group server. none - Normally, the method is listed as the last method. The user will pass authentication if it is not denied by previous method authentication. Default No AAA authentication method is configured. Command Mode Global Configuration Mode. Command Default Level Level: 15. Usage Guideline Use this command to configure the default authentication method list for MAC authentication. Initially, the default method list is not configured. The authentication of MAC request will be performed based on the local database. Example This example shows how to set the default methods list for authenticating mac-auth users. Switch#configure terminal Switch(config)# aaa authentication mac-auth default group radius 7-9 aaa authentication web-auth This command is used to configure the default method list used for Web authentication. Use the no command to remove the default method list. aaa authentication web-auth default METHOD1 [METHOD2...] no aaa authentication web-auth default Parameters METHOD1 [METHOD2...] Specifies the list of methods that the authentication algorithm tries in the given sequence. Enter at least one method or enter up to four methods. The following are keywords that can be used to specify a method. local – Specifies to use the local database for authentication. group radius – Specifies to use the servers defined by the RADIUS server host command. group GROUP-NAME – Specifies to use the server groups defined by the AAA group server. none - Normally, the method is listed as the last method.
