Views System view Predefined user roles network-admin Parameters fcf: Specifies the FCF mode. npv: Specifies the NPV mode. transit: Specifies the Transit mode. Usage guidelines The switch supports the following FCoE modes: • FCF mode—A switch operating in this mode is called an FCF switch. Its VFC interfaces support E mode (E_Port) and F mode (F_Port). • NPV mode—A switch operating in this mode is called an NPV switch. Its VFC interfaces support F mode (F_Port) and NP mode (NP_Port). • Transit mode—A switch operating in this mode is called a Transit switch. Its Ethernet interfaces can operate in ENode mode or FCF mode. An FC and FCoE-capable switch can operate in the following modes: • FCF mode—When the switch is operating in this mode, it can perform one of the following operations: � Connect to the E_Port on another FCF switch through its E_Port. � Connect to the N_Port on a node or the NP_Port on an NPV switch through its F_Port. • NPV mode—When the switch is operating in this mode, it can perform one of the following operations: � Connect to the N_Port on a node through its F_Port. � Connect to the F_Port on an FCF switch through its NP_Port. • Transit mode—When the switch is operating in this mode, you can do perform one of the following tasks: � Restrict its Ethernet interface to receiving traffic only from an ENode by configuring the interface to operate in ENode mode. � Restrict its Ethernet interface to receiving traffic only from an FCF switch by configuring the interface to operate in FCF mode. • Non-FCoE mode—When the switch is operating in this mode, it is a standard switch and does not provide any FC or FCoE capabilities. The switch can only convert from non-FCoE mode to one FCoE mode, or vice versa. It cannot convert directly among FCoE modes. To convert among FCoE modes, first convert the switch to non-FCoE mode. After converting the switch to non-FCoE mode, FC and FCoE-related configurations in the original FCoE mode are cleared. Examples # Configure the switch to operate in FCF mode.

# Convert the switch operating in FCF mode to NPV mode. [Sysname] undo fcoe-mode All current FC configuration will be lost. Continue?

To bring up the interface, execute the undo shutdown command. • Stby—The interface is a standby interface. Cause Causes for the physical state of the FC interface to be Down: • Not connected—No physical connection exists (possibly because the network cable is disconnected or faulty). • Administratively—The port was shut down by using the shutdown command. To bring up the interface, use the undo shutdown command. fc mode (FC interface view) Use fc mode to configure the mode of an FC interface. Use undo fc mode to restore the default. Syntax fc mode { auto | e | f | np } undo fc mode Default On an FCF switch, the mode of an FC interface is auto. On an NPV switch, the mode of an FC interface is F. Views FC interface view Predefined user roles network-admin Parameters auto: Specifies the auto mode, so that the FC interface can operate in F mode or E mode through dynamic negotiation. e: Specifies the E mode. f: Specifies the F mode. np: Specifies the NP mode. Usage guidelines An FC switch supports E, F, and auto modes. An NPV switch supports F and NP modes. Examples # Configure the mode of interface FC 1/0/1 as E. system-view [Sysname] interface fc 1/0/1

fcb2bcredit Use fcb2bcredit to configure the Buffer-to-Buffer Credit (BB_ Credit) value for an FC interface. Use undo fcb2bcredit to restore the default. Syntax fcb2bcredit credit-value undo fcb2bcredit Default The BB_Credit value for an FC interface is 15. Views FC interface view Predefined user roles network-admin Parameters credit-value: Specifies the number of packets that the FC interface can continuously receive, in the range of 1 to 15. Usage guidelines The BB_ Credit is a flow control mechanism used to ensure that an FC interface does not drop packets. The BB_Credit value is configurable. Typically, you do not need to change the default value. Examples # Set the BB_Credit value to 10 for interface FC 1/0/1. system-view [Sysname] interface fc 1/0/1 [Sysname-Fc1/0/1] fcb2bcredit 10 fill-word Use fill-word to configure the fill word mode of an FC interface operating at 8 Gbps. Use undo fill-word to restore the default. Syntax fill-word { idle-arbff | idle-idle } undo fill-word Default The fill word mode is idle-arbff for an FC interface operating at 8 Gbps. Views FC interface view

network-admin Parameters idle-arbff: Specifies the idle-arbff mode. This mode uses the idle primitive signal in the link initialization phase and uses the ARBff primitive signal as the fill word. idle-idle: Specifies the idle-idle mode. This mode uses the idle primitive signal in the link initialization phase and uses the idle primitive signal as the fill word. Usage guidelines This command is available on only FC interfaces operating at 8 Gbps. This command does not take effect on FC interface operating at 2 Gbps or 4 Gbps, and these FC interfaces supports only the fill word mode idle-idle. When FC interfaces operating at 8 Gbps fail to communicate, you can use this command to adjust the fill word of these FC interfaces. To make the fill word mode configuration take effect, you must re-enable the FC interface by using the shutdown command and then the undo shutdown command. Examples # Configure the fill word mode as idle-idle for FC 1/0/1 operating at 8 Gbps. system-view [Sysname] interface fc 1/0/1 [Sysname-Fc1/0/1] speed 8000 [Sysname-Fc1/0/1] fill-word idle-idle Related commands speed interface fc Use interface fc to enter FC interface view.

Syntax In Layer 2 Ethernet interface view: port-type fc In FC interface view: port-type ethernet Default A Layer 2 Ethernet interface is not changed to an FC interface. Views Layer 2 Ethernet interface view, FC interface view Predefined user roles network-admin Parameters ethernet: Changes an FC interface back to a Layer 2 Ethernet interface. fc: Changes a Layer 2 Ethernet interface to an FC interface. Usage guidelines Layer 2 Ethernet interfaces can be changed to FC interfaces. To change a Layer 2 Ethernet interface to an FC interface, use the port-type fc command in Layer 2 Ethernet interface view. To change an FC interface back to a Layer 2 Ethernet interface, use the port-type ethernet command in FC interface view. When the port type of an interface is changed, the following events occur: • The original interface is deleted. • A new interface is created with the same interface number as the original interface. Examples # Change interface Ten-GigabitEthernet 1/0/1 to interface FC 1/0/1. system-view [Sysname] interface ten-gigabitethernet 1/0/1 [Sysname-Ten-GigabitEthernet1/0/1] port-type fc [Sysname-Fc1/0/1] reset counters interface Use reset counters interface to clear statistics for FC interfaces. Syntax reset counters interface [ fc [ interface-number ] ]

network-admin Parameters interface-number: Specifies an FC interface by its number. Usage guidelines Use this command to clear history statistics if you want to collect traffic statistics for a specific time period. If you do not specify the fc keyword, this command clears statistics for all interfaces. If you specify the fc keyword, this command clears statistics for all FC interfaces. If you specify an FC interface, this command clears statistics for the specified FC interface. Examples # Clear statistics for interface FC 1/0/1. reset counters interface fc 1/0/1 Related commands display interface fc shutdown Use shutdown to shut down an FC interface. Use undo shutdown to bring up an FC interface. Syntax shutdown undo shutdown Default An FC interface is up. Views FC interface view Predefined user roles network-admin Examples # Shut down interface FC 1/0/1. system-view [Sysname] interface fc 1/0/1 [Sysname-Fc1/0/1] shutdown speed Use speed to configure the rate for an FC interface.

Syntax speed { 1000 | 2000 | 4000 | 8000 | 16000 | auto } undo speed Default The rate of an FC interface is autonegotiated. Views FC interface view Predefined user roles network-admin Parameters 1000: Configures the interface rate as 1000 Mbps. 2000: Configures the interface rate as 2000 Mbps. 4000: Configures the interface rate as 4000 Mbps. 8000: Configures the interface rate as 8000 Mbps. 16000: Configures the interface rate as 16000 Mbps. auto: Configures the interface to negotiate its rate with the peer. Usage guidelines The switch series does not support the 1000 and 16000 keywords of the command. When you configure the 1000 or 16000 keyword for the command, the system prompts that "Such configuration is not supported." Examples # Set the rate to 8000 Mbps for interface FC 1/0/1. system-view [Sysname] interface fc 1/0/1 [Sysname-Fc1/0/1] speed 8000 VFC interface commands bandwidth Use bandwidth to configure the expected bandwidth of a VFC interface. Use undo bandwidth to restore the default. Syntax bandwidth bandwidth-value undo bandwidth Default The expected bandwidth (in kbps) is the interface baud rate divided by 1000.

Predefined user roles network-admin Parameters bandwidth-value: Specifies the expected bandwidth in the range of 1 to 400000000 kbps. Usage guidelines The expected bandwidth determines the cost of the interface, which is used for route calculation. By default, the baud rate of a VFC interface is 10 Gbps. Examples # Set the expected bandwidth of interface VFC 1 to 50 kbps. system-view [Sysname] interface vfc 1 [Sysname-Vfc1] bandwidth 50 bind interface Use bind interface to bind a VFC interface to an Ethernet interface. Use undo bind interface to remove a VFC-to-Ethernet interface binding. Syntax bind interface interface-type interface-number [ mac mac-address ] undo bind interface Default A VFC interface is not bound to any Ethernet interface. Views VFC interface view Predefined user roles network-admin Parameters interface-type interface-number: Specifies an interface by its type and number. The interface type can be one of the following: • Layer 2 Ethernet interface. • Layer 2 aggregate interface. • S-channel interface. • S-channel aggregate interface. mac mac-address: Specifies the bound peer FCoE MAC address, in the format of XXXX-XXXX-XXXX and six bytes in length.

receives packets through the Ethernet interface bound to it. To use one physical link to carry multiple VFC interfaces, you must bind these VFC interfaces to different peer FCoE MAC addresses. However, you can bind them to one Ethernet interface. The FCoE MAC address identifies the device that communicates with a VFC interface. For a point-to-multipoint network, the FCoE MAC address is required. For a point-to-point network, the FCoE MAC address is optional. You can use the display fcoe command to display the FCoE MAC address of a switch. You can display the FCoE MAC address of an ENode through some software or the NMS. A VFC interface can be bound to only one Ethernet interface and to only one FCoE MAC address. An Ethernet interface can be bound to multiple VFC interfaces, but an FCoE MAC address can be bound to only one VFC interface. You must change the switch to the expert mode before binding a VFC interface to an S-channel interface or S-channel aggregate interface. Otherwise, the binding will fail. The switch supports FCoE over S-channel capabilities only when it is operating in expert mode. For information about system operating modes, see Fundamentals Configuration Guide. For information about S-channel interfaces and S-channel aggregate interfaces, see EVB Configuration Guide. To successfully bind a VFC interface to a Layer 2 Ethernet interface, make sure the Layer 2 Ethernet interface is FCoE capable. To successfully bind a VFC interface to a Layer 2 aggregate interface, make sure all member ports of the Layer 2 aggregate interface are FCoE capable. New member ports of the Layer 2 aggregate interface must also be FCoE capable. To successfully bind a VFC interface to an S-channel interface, make sure the Layer 2 Ethernet interface associated with the S-channel interface has FCoE over S-channel capabilities. To successfully bind a VFC interface to an S-channel aggregate interface, make sure all member ports of the Layer 2 Ethernet aggregate interface associated with the S-channel aggregate interface have FCoE over S-channel capabilities. New member ports of the Layer 2 Ethernet aggregate interface must also have FCoE over S-channel capabilities. Otherwise, FCoE traffic might be blocked. For FCoE-capable cards and cards that have FCoE over S-channel capabilities, see the specific product manual. The binding to the Layer 2 aggregate interface does not take effect when you perform the following tasks: • Bind one VFC interface to a Layer 2 aggregate interface. • Bind another VFC interface to a Layer 2 Ethernet interface that is a member port of the Layer 2 aggregate interface. The binding to an S-channel aggregate interface does not take effect when you perform the following tasks: • Bind one VFC interface to the S-channel aggregate interface. • Bind another VFC interface to a member port of the Layer 2 aggregate interface associated with the S-channel aggregate interface. Enabling EVB on a Layer 2 Ethernet interface or Layer 2 aggregate interface disables the interface from forwarding FCoE traffic. To enable such an interface to forward FCoE traffic, you must create an S-channel interface or S-channel aggregate interface and bind a VFC interface to the created interface. FCoE over S-channel can be used only between an EVB-capable switch and a server. Examples # Bind interface VFC 4 to interface Ten-GigabitEthernet 1/0/1 and FCoE MAC address 000c-2999-eacd.

Views FC interface view Predefined user roles network-admin Parameters group-number: Specifies an FC aggregation group by its group number. An FC aggregation group uniquely corresponds to an FC aggregate interface, and they are numbered the same. Usage guidelines An FC interface can be assigned to only one FC aggregation group. After an FC interface is assigned to an FC aggregation group, its operating mode, trunk mode, trunk VSAN, and access VSAN configurations are cleared. Also, you cannot configure these configurations for a member interface. After the FC interface is removed from the FC aggregation group, these configurations are not restored, and the default settings of these configurations are used. An FC aggregation group can have a maximum of eight member interfaces. Examples # Assign FC interface FC 1/0/1 to FC aggregation group 2. system-view [Sysname] interface fc 1/0/1 [Sysname-Fc1/0/1] san-aggregation group 2 Current FC mode, trunk mode, trunk VSAN, and access VSAN configuration of the in

Related commands display san-aggregation san-aggregation load-sharing mode local-first Use san-aggregation load-sharing mode local-first to enable local-first load sharing. Use undo san-aggregation load-sharing mode local-first to disable local-first load sharing. Syntax san-aggregation load-sharing mode local-first undo san-aggregation load-sharing mode local-first Default Local-first load sharing is enabled. Views System view Predefined user roles network-admin Usage guidelines Local-first load sharing reduces the influence of traffic on the links between physical IRF ports. For example, in an IRF fabric, an IRF member device forwards traffic out of an FC aggregate interface with the member interfaces distributed on multiple IRF member devices. The system processes the traffic as follows based on the configurations on IRF member device. • When local-first load sharing is enabled on the IRF member device, the following rules apply: � If the IRF member device has Selected member interfaces, traffic is load-shared among the Selected interfaces of the IRF member device. � If the IRF member device does not have Selected member interface, traffic is load-shared among all Selected member interfaces on all IRF member devices. • When local-first load sharing is disabled on the IRF member device, the traffic is load-shared among all Selected member interfaces on all IRF member devices. For more information about IRF, see IRF Configuration Guide. Local-first load sharing takes effect immediately after it is configured, and it might cause traffic loss. Examples # Enable local-first load sharing. system-view [Sysname] san-aggregation load-sharing mode local-first shutdown Use shutdown to shut down an FC aggregate interface. Use undo shutdown to bring up an FC aggregate interface.

and unsolicited Discovery Advertisements. Related commands • fcoe fcmap • fcoe fka-adv-period • fcoe global fcf-priority fcoe enable Use fcoe enable to enable FCoE for a VLAN and map the VLAN to a VSAN. Use undo fcoe enable to disable FCoE for the VLAN. Syntax fcoe enable [ vsan vsan-id ] undo fcoe enable Default FCoE is disabled for a VLAN. Views VLAN view Predefined user roles network-admin Parameters vsan vsan-id: Specifies a VSAN by its ID in the range of 1 to 3839. If you do not specify a VSAN, this command maps the VLAN to a VSAN with the same ID as the VLAN. For VLANs 3840 to 4094, you must specify VSANs to be mapped. Usage guidelines To use an FC or VFC interface to transmit packets, you must enable FCoE. When you use an FC interface to transmit packets, you must map its access VSAN and trunk VSANs to VLANs and enable FCoE for the VLANs. This allows the switch to correctly run FC and FCoE features. When you use a VFC interface to transmit packets, the Ethernet interface bound to the VFC interface might allow multiple VLANs. You must enable FCoE for a VLAN and map the VLAN to a VSAN. This allows the packets from the VSAN to be tagged with the VLAN tag and transmitted within the VLAN. FCoE cannot be enabled for VLAN 1. VSANs are mapped to VLANs on a one-to-one basis. When you use an FC interface to transmit packets, the VSAN used on the two ends can be mapped to the same VLAN or different VLANs. When you use a VFC interface to transmit packets, enable FCoE for the same VLAN and map this VLAN to the same VSAN on the two ends. After you enable FCoE for a VLAN, the following changes occur to the VLAN: • An FCoE-capable VLAN allows only FCoE traffic.

you do not need to enable STP or other loop detection protocols in an FCoE-capable VLAN. Otherwise, FCoE links might be blocked. • A Layer 2 protocol enabled in an FCoE-capable VLAN runs based on the topology where all member ports in the FCoE-capable VLAN are isolated at Layer 2. Examples # Enable FCoE on VLAN 4 and map VLAN 4 to VSAN 6. system-view [Sysname] vlan 4 [Sysname-vlan4] fcoe enable vsan 6 fcoe fcf-priority Use fcoe fcf-priority to configure the FCF priority for a VFC interface. Use undo fcoe fcf-priority to restore the default. Syntax fcoe fcf-priority priority undo fcoe fcf-priority Default The FCF priority of a VFC interface is 128. Views VFC interface view Predefined user roles network-admin Parameters priority: Specifies the FCF priority for the VFC interface, in the range of 0 to 255. The smaller the value, the higher the priority. Usage guidelines The VFC interface FCF priority is used in the fcf priority field in an unsolicited Discovery Advertisement. An ENode selects the FCF switch with the highest priority from the FCF switches sending Discovery Advertisements and sends a FLOGI request to it for login. This command is takes effect on only VFC interfaces operating in F mode. You can configure this command on VFC interfaces operating in E mode, but it does not take effect. Examples # Configure the FCF priority as 12 for interface VFC 1. system-view [Sysname] interface vfc 1 [Sysname-Vfc1] fcoe fcf-priority 12

Use undo fcoe fcmap to restore the default. Syntax fcoe fcmap fc-map undo fcoe fcmap Default The FC-MAP value is 0x0EFC00. Views System view Predefined user roles network-admin Parameters fc-map: Specifies an FC-MAP value in the range of 0x0EFC00 to 0x0EFCFF. Usage guidelines An FC-MAP value identifies an FCoE network. Switches in the same FCoE network must have the same FC-MAP value. After an FC-MAP value is configured, VFC interfaces perform an FIP renegotiation. Examples # Configure the FC-MAP value as 0x0EFCFF. system-view [Sysname] fcoe fcmap 0efcff Changing the FC-MAP will flap all VFC interfaces. Continue? [Y/N]: fcoe fka-adv-period Use fcoe fka-adv-period to configure an FKA advertisement interval. Use undo fcoe fka-adv-period to restore the default. Syntax fcoe fka-adv-period fka-adv-period undo fcoe fka-adv-period Default The FKA advertisement interval is 8 seconds. Views System view Predefined user roles network-admin

Usage guidelines The FKA advertisement interval determines the length of time the switch takes to detect the disconnection of a virtual link. The FKA advertisement interval defines the interval for a switch to send unsolicited Discovery Advertisements to its peer switches or ENodes. If the peer switch or ENode fails to receive unsolicited Discovery Advertisements within 2.5 FKA advertisement intervals, it deletes the virtual link. The FKA advertisement interval is carried in received unsolicited Discovery Advertisements instead of being configured on the local switch. If the switch fails to receive keepalive frames from the peer ENode within 2.5 FKA advertisement intervals, it also deletes the virtual link. When configuring the FKA advertisement interval value on an FCF or NPV switch, use Table 13 as a reference to avoid service disruption. Table 13 Recommended values for different application scenarios Recommended value Application scenarios Remarks Less than 90 seconds Connected to servers, storage devices, or third-party switches. According to FC-BB-5, the upper limit of the FKA advertisement interval value is 90 seconds. In this scenario, an FCF switch or NPV switch operating in standalone mode or in IRF mode but without subordinate switches will experience FCoE traffic disruption during an ISSU reboot for the following reasons: • The ISSU reboot takes more than 225 (2.5*90) seconds. • The peer deletes the virtual link for failing to receive unsolicited Discovery Advertisements within 225 seconds. You must adjust the FKA advertisement interval value on the upstream FCF switch to ensure service continuity in either of the following situations: • An active/standby switchover on an NPV switch • An ISSU reboot on an IRF member NPV switch with subordinate switches. The preceding steps are required for the following reasons: • The FKA advertisement interval value configured on the NPV switch affects only its VFC interfaces in F mode and connected ENodes. • The VFC interfaces in NP mode of the NPV switch use the FKA advertisement interval value learned from the upstream FCF switch.

the switch takes more than 2.5 x 60 seconds because of the amount of FCoE configuration. ISSU reboot on an IRF member switch with subordinate switches takes more than 2.5 x 60 seconds because of the amount of FCoE configuration. For more information about ISSU, see Fundamentals Configuration Guide. 300–600 seconds ISSU reboot on a switch operating in standalone mode or in IRF mode but without subordinate switches and connecting to no nodes. During an ISSU reboot on a switch operating in standalone mode or in IRF mode but without subordinate switches, the switch cannot send unsolicited Discovery Advertisements or keepalive frames. Examples # Configure the FKA advertisement interval as 20 seconds. system-view [Sysname] fcoe fka-adv-period 20 fcoe global fcf-priority Use fcoe global fcf-priority to configure the system FCF priority. Use undo fcoe global fcf-priority to restore the default. Syntax fcoe global fcf-priority priority undo fcoe global fcf-priority Default The system FCF priority is 128. Views System view Predefined user roles network-admin Parameters priority: Specifies the system FCF priority in the range of 0 to 255. The smaller the value, the higher the priority. Usage guidelines The system FCF priority is used in the fcf priority field in an unsolicited Discovery Advertisement. An ENode selects the FCF switch with the highest priority from the FCF switches sending Discovery Advertisements and sends a FLOGI request to it for login. This command takes effect on all VFC interfaces operating in F mode.

port Use port to assign the specified interfaces to a VSAN as access ports in batch. Use undo port to remove the specified interfaces from a VSAN in batch. Syntax port interface-list undo port interface-list Default All interfaces belong to VSAN 1 as access ports. Views VSAN view Predefined user roles network-admin Parameters interface-list: Specifies a space-separated list of up to 10 interface items. Each item specifies an interface or a range of interfaces in the form of interface-type interface-number1 to interface-type interface-number2. The value for interface-number2 must be greater than or equal to the value for interface-number1. The interface type can only be FC interface. Usage guidelines This command has the same effect as configuring the port access vsan command in interface view of each interface in the interface list. Examples # Assign interfaces FC 1/0/1 through FC 1/0/10 to VSAN 10 as access ports in batch. system-view [Sysname] vsan 10 [Sysname-vsan10] port fc 1/0/1 to fc 1/0/10 Related commands port access vsan port access vsan Use port access vsan to assign an interface to a VSAN as an access port.

Usage guidelines To assign multiple interfaces to a VSAN as access ports in batch, use the port command. Examples # Assign interface FC 1/0/1 to VSAN 10 as an access port. system-view [Sysname] vsan 10 [Sysname-vsan10] quit [Sysname] interface fc 1/0/1 [Sysname-Fc1/0/1] port access vsan 10 Related commands port port trunk mode Use port trunk mode to configure the trunk mode of an interface. Use undo port trunk mode to restore the default. Syntax port trunk mode { auto | off | on } undo port trunk mode Default On an FCF switch, the trunk mode of an interface is auto. On an NPV switch, the trunk mode of an interface is off. Views FC interface view, FC aggregate interface view Predefined user roles network-admin Parameters auto: Specifies the auto mode. off: Specifies the off mode. on: Specifies the on mode. Usage guidelines The trunk mode of an interface can be auto, on, or off.

all these modes. • When the switch is operating in NPV mode, its FC interfaces and FC aggregate interfaces support only on and off modes. The two interfaces of a link use the Exchange Virtual Fabrics Parameters (EVFP) protocol to negotiate whether to support VSAN tagging according to the trunk modes. Only FC interfaces and FC aggregate interfaces support the trunk mode. Examples # Configure the trunk mode of interface FC 1/0/1 as On. system-view [Sysname] interface fc 1/0/1 [Sysname-Fc1/0/1] port trunk mode on port trunk vsan Use port trunk vsan to assign an interface to the specified VSANs as a trunk port. Use undo port trunk vsan to remove an interface from the specified VSANs. Syntax port trunk vsan vsan-id-list undo port trunk vsan vsan-id-list Default An interface is not assigned to any VSAN as a trunk port. Views FC interface view, VFC interface view, FC aggregate interface view Predefined user roles network-admin Parameters vsan-id-list: Specifies a space-separated list of up to 10 VSAN items. Each item specifies a VSAN or a range of VSANs in the form of vsan-id1 to vsan-id2. The value for vsan-id2 must be greater than or equal to the value for vsan-id1. Examples # Assign interface FC 1/0/1 to VSANs 1, 2, 10, and 20 through 100. system-view [Sysname] interface fc 1/0/1 [Sysname-Fc1/0/1] port trunk vsan 1 to 2 10 20 to 100 # Assign interface VFC 1 to VSANs 1, 2, 10, and 20 through 100. system-view [Sysname] interface vfc 1 [Sysname-Vfc1] port trunk vsan 1 to 2 10 20 to 100

Views System view Predefined user roles network-admin Parameters vsan vsan-id: Specifies a VSAN by its ID in the range of 1 to 3839. Usage guidelines You cannot create or delete VSAN 1, because it is the system-default VSAN. You can create VSANs 2 to 3839. The maximum number of VSANs (including VSAN 1) that can be created is 16. Examples # Create VSAN 10 and enter its view. system-view [Sysname] vsan 10 [Sysname-vsan10] Fabric building commands allowed-domain-id Use allowed-domain-id to configure an allowed domain ID list for a VSAN. Use undo allowed-domain-id to restore the default. Syntax allowed-domain-id domain-id-list undo allowed-domain-id domain-id-list Default The allowed domain ID list includes domain IDs 1 to 239.

network-admin Parameters domain-id-list: Specifies a space-separated list of up to 8 domain items. Each item specifies a domain ID or a range of domain IDs in the form of domain-id1 to domain-id2. The value for domain-id2 must be greater than or equal to the value for domain-id1. The value range for the domain-id argument is 1 to 239. Usage guidelines Each FC switch is assigned a domain ID. You can configure an allowed domain ID list. To successfully configure an allowed domain ID list on the principal switch, make sure all assigned and locally configured domain IDs are included in the list. After you configure an allowed domain ID list, the principal switch assigns only domain IDs available in the allowed list. To successfully configure an allowed domain ID list on a non-principal switch, make sure the runtime domain ID of the switch is included in the allowed list. After you configure an allowed domain ID list on a non-principal switch, the following rules apply: • The locally configured domain ID must be included in the allowed list. Otherwise, the domain ID configuration fails. • The principal switch must assign a domain ID that is included in the allowed list of the non-principal switch. Otherwise, the non-principal switch refuses the assigned domain ID and isolates its interface connected to the principal switch. HP recommends that you configure the same allowed domain ID list for all switches in a VSAN. Examples # Configure VSAN 1 to allow domains 3 through 10. system-view [Sysname] vsan 1 [Sysname-vsan1] allowed-domain-id 3 to 10 display fc domain Use display fc domain to display the domain information of a VSAN.

Use undo domain auto-reconfigure enable to disable automatic reconfiguration in a VSAN . Syntax domain auto-reconfigure enable undo domain auto-reconfigure enable Default Automatic reconfiguration is disabled in each VSAN. Views VSAN view Predefined user roles network-admin Usage guidelines This command takes effect only when the fabric configuration function is enabled. A fabric reconfiguration triggers a principal switch selection phase. A disruptive reconfiguration is automatically performed if the domain ID lists overlap when two fabrics are merged. A nondisruptive reconfiguration is automatically performed when one of the following conditions exists: • When two fabrics are merged, the principal switch information of the two fabrics is different, and the domain ID lists are not empty and do not overlap. • A principal link in a fabric goes down. Examples # Enable the automatic reconfiguration function in VSAN 1. system-view [Sysname] vsan 1 [Sysname-vsan1] domain auto-reconfigure enable Related commands domain configure enable

Use domain configure enable to enable the fabric configuration function for the switch in a VSAN. Use undo domain configure enable to disable the fabric configuration function for the switch in a VSAN. Syntax domain configure enable undo domain configure enable Default The fabric configuration function is enabled in a VSAN. Views VSAN view Predefined user roles network-admin Usage guidelines After you enable the fabric configuration function on FC switches, the switches exchange messages to select the principal switch. Then, the principal switch dynamically assigns domain IDs to all switches in the fabric. After you disable the fabric configuration function on FC switches, the switches will not select a principal switch and cannot obtain domain IDs dynamically. You must configure a unique domain ID for each switch. • To dynamically build a fabric, you must enable the fabric configuration function on switches. • To statically build a fabric, you must disable the fabric configuration function on switches and manually configure domain IDs for the switches. Examples # Enable the fabric configuration function for the switch in VSAN 1. system-view [Sysname] vsan 1 [Sysname-vsan1] domain configure enable domain restart Use domain restart to manually initiate a fabric reconfiguration in a VSAN. Syntax domain restart [ disruptive ] Views VSAN view Predefined user roles network-admin Parameters disruptive: Initiates a disruptive reconfiguration. If you do not specify this keyword, the command initiates a nondisruptive reconfiguration.

A fabric reconfiguration triggers a principal switch selection phase. A fabric reconfiguration can be disruptive or nondisruptive. A fabric reconfiguration can be disruptive or nondisruptive. • Disruptive reconfiguration—Floods Reconfigure Fabric (RCF) frames throughout the fabric and notifies all switches to perform a disruptive reconfiguration. During the reconfiguration procedure, each switch clears all data and performs renegotiation, and data transmission in the fabric is disrupted. • Nondisruptive reconfiguration—Floods Build Fabric (BF) frames throughout the fabric and notifies all switches to perform a nondisruptive reconfiguration. During the reconfiguration procedure, each switch tries to save the last running data for its domain ID to remain unchanged. Thus, data transmission in the fabric is not disrupted. For fabric settings that do not take effect immediately (for example, switch priority), you can perform a disruptive reconfiguration to make them take effect. Examples # Manually initiate a disruptive reconfiguration in VSAN 1. system-view [Sysname] vsan 1 [Sysname-vsan1] domain restart disruptive The command may cause traffic interruption. Continue? [Y/N]:y Related commands domain configure enable domain-id Use domain-id to configure a domain ID for the switch in a VSAN. Use undo domain-id to restore the default. Syntax domain-id domain-id { preferred | static } undo domain-id Default The domain ID is 0 preferred in a VSAN. Views VSAN view Predefined user roles network-admin Parameters domain-id: Specifies a domain ID in the range of 1 to 239. preferred: Specifies the domain ID as preferred.

Usage guidelines The upper-layer protocol identifies only the WWN, but FC switches use domain IDs to route and forward packets. Domain IDs are assigned on a per-VSAN basis and have a default value of 0, which cannot distinguish switches. Therefore, you must statically configure or dynamically assign domain IDs for FC switches. In the static domain ID assignment method, the ID type configuration does not affect the assignment result. In the dynamic domain ID assignment method, the principal switch assigns a domain ID to each switch in the fabric. If a member switch fails to get a preferred domain ID from the principal switch, it accepts any other domain ID assigned by the principal switch. If the member switch fails to get a static domain ID, it does not accept any other domain ID and isolates the upstream principal link. HP recommends that you configure domain IDs of the same type for all switches in a VSAN. Examples # Configure static domain ID 55 in VSAN 1. system-view [Sysname] vsan 1 [Sysname-vsan1] domain-id 55 static Non-disruptive reconfiguration or isolating the switch may be performed. Continue? [Y/N]: fabric-name Use fabric-name to configure a fabric name in a VSAN. Use undo fabric-name to restore the default. Syntax fabric-name name undo fabric-name Default The fabric name is the WWN of the switch. Views VSAN view Predefined user roles network-admin Parameters name: Specifies a fabric name, in the format of xx:xx:xx:xx:xx:xx:xx:xx, where x is a hexadecimal number. Usage guidelines An FC switch supports assigning a fabric name to each VSAN, in the same format as the WWN (a 64-bit address).

fabric name on all switches in a VSAN. In a dynamically built fabric, each VSAN uses the WWN of the principal switch as the fabric name. Examples # Configure a fabric name of 10:11:12:13:14:15:16:17 in VSAN 1. system-view [Sysname] vsan 1 [Sysname-vsan1] fabric-name 10:11:12:13:14:15:16:17 fc domain rcf-reject Use fc domain rcf-reject to configure an interface to reject the ReConfigure Fabric (RCF) requests received in a VSAN. Use undo fc domain rcf-reject to restore the default. Syntax fc domain rcf-reject vsan vsan-id undo fc domain rcf-reject vsan vsan-id Default An interface does not reject the received RCF requests. Views FC interface view, FC aggregate interface view, VFC interface view Predefined user roles network-admin Parameters vsan vsan-id: Specifies a VSAN by its ID in the range of 1 to 3839. Usage guidelines In a stable fabric, to avoid unnecessary disruptive reconfigurations, you can configure an interface to reject the RCF requests received in a VSAN. With this feature, the switch replies with a reject message and isolates the interface that receives an RCF request. Examples # Configure interface FC 1/0/1 to reject the RCF requests received in VSAN 1. system-view [Sysname] interface fc 1/0/1 [Sysname-Fc1/0/1] fc domain rcf-reject vsan 1 # Configure interface VFC 1 to reject the RCF requests received in VSAN 1. system-view [Sysname] interface vfc 1 [Sysname-Vfc1] fc domain rcf-reject vsan 1 fc name-service auto-discovery Use fc name-service auto-discovery to enable SCSI-FCP information autodiscovery.

Syntax fc name-service auto-discovery undo fc name-service auto-discovery Default Auto discovery of SCSI-FCP information is enabled. Views VSAN view Predefined user roles network-admin Usage guidelines In some situations, for example, when a node logs out and then logs back in, the node does not register SCSI-FCP support. Therefore, the node does not have a Feature value. This might cause communication failure between the node and other nodes. This feature enables the switch to automatically obtain SCSI-FCP support and the Feature value by sending a PRLI packet to the node that is logging in. Then, the switch stores the SCSI-FCP information in the name service database. NOTE: After this feature is enabled, nodes with older-model HBAs might not actively register name service information with the switch. Examples # Enable SCSI-FCP information autodiscovery in VSAN 2. system-view [Sysname] vsan 2 [Sysname-vsan2] fc name-server auto-discovery fc timer distributed-services Use fc timer distributed-services to specify the global distributed service timeout period. Use undo fc timer distributed-services to restore the default.

Views System view Predefined user roles network-admin Parameters wwn-value: Specifies an N_Port by its WWN in the format of xx:xx:xx:xx:xx:xx:xx:xx (hexadecimal). type-value: Specifies a supported FC4-Type by its value in the range of 0 to 255. The FC4-Type field is 256 bits, each of which represents an FC4-Type. If a bit is set to 1, the FC4-Type that the bit represents is supported. Only one bit can be set to 1 at the same time. scsi-fcp: Specifies the supported FC4-Type as SCSI-FCP, which has a type-value of 8. feature feature-map: Specifies the Feature value for the supported FC4-Type. The value range for feature-map is 0 to 15. The Feature field is 4 bits, each of which represents a Feature. If a bit is set to 1, the Feature that the bit represents is supported. Multiple bits can be set to 1 at the same time. For example, if the value is set to 15, the node supports four Features of the FC4-Type. If the value is set to 0, the node supports none of the four Features. When you specify supported FC4-Type as SCSI-FCP, you can configure the following keywords: • initiator: Specifies support for the initiator Feature, which has a feature-map of 2. • target: Specifies support for the target Feature, which has a feature-map of 1. • both: Specifies support for both initiator and target Features, which has a feature-map of 3. Usage guidelines The switch records the default FC4 information in the name service database for a node when the following conditions exist: • The node does not register FC4 information. • The switch fails to obtain SCSI-FCP information from the node. The switch replaces the default FC4 information with the registered FC4 information or obtained SCSI-FCP information when one of the following events occurs: • A node registers FC4 information. • The switch obtains the SCSI-FCP information. This command can configure only one combination of FC4-Type and Feature at a time. Examples # Configure the default FC4 information for the node with WWN 00:00:00:11:22:33:44:55. system-view [Sysname] fc wwn 00:00:00:11:22:33:44:55 default-fc4-type scsi-fcp feature target [Sysname] fc wwn 00:00:00:11:22:33:44:55 default-fc4-type 9 feature 7 priority Use priority to configure the switch priority in a VSAN.

Use undo wwn area-port-id to remove a WWN-to-FC address binding. Syntax wwn wwn-value area-port-id area-port-id-value

Default The WWN of an N_Port is not bound to any FC address. Views VSAN view Predefined user roles network-admin Parameters wwn-value: Specifies the WWN of the N_Port, in the format of xx:xx:xx:xx:xx:xx:xx:xx, where x is a hexadecimal number. area-port-id-value: Specifies the area ID and port ID in the format of xxxx, where x is a hexadecimal number. The first two digits indicate the area ID, and the last two digits indicate the port ID. Usage guidelines The switch assigns the FC address bound to an N_Port when the N_Port requests an FC address. However, if the N_Port has been assigned another FC address or the FC address has been assigned to another N_Port, the binding fails. The N_Port here indicates an N_Port on a node or an NP_Port on an NPV switch. The WWN of an N_Port can be bound to only one FC address, and vice versa.

If you do not specify an exchange ID, this command displays all link exchange entries. slot slot-number: Specifies an IRF member device by its member ID (slot number). If you do not specify an IRF member device, this command displays exchange entries for the master device. Usage guidelines The exchange is a basic concept of FC. All data frames and control frames are transmitted based on the exchange. An exchange indicates one data exchange between communication entities and can contain multiple bidirectional packet exchanges. An exchange pair (initiating exchange and responding exchange) must be created for each data exchange. Service classes that provide reliable transmission services (classes 1, 2, and 6) perform packet acknowledgment, error detection, and packet retransmission based on the exchange pair. Exchanges include the following categories: • Protocol exchange—Created only at the server end based on the protocol number and VSAN ID and used to monitor connection establishment. • Link exchange—Created at both ends based on the exchange ID and used for packet exchange. Examples # Display the protocol exchange entries. display fc exchange protocol slot 1 Local_ID:EXID Remote_ID:EXID State Slot Protocol 0x000000:65535 0x000000:65535 LISTEN 1 6 # Display the link exchange entries. display fc exchange link slot 2 Local_ID:EXID Remote_ID:EXID State Slot Protocol 0x060501:1024 0x010001:1025 ESTABLISHED 2 8 # Display detailed information about the link exchange entries. display fc exchange link verbose slot 1 slot: 1 protocol: 8 connection info: Local = 0x090801:1155 , Remote = 0x050001:1089 PCB flags: 0x2 FC Class: FC_CLASS_F connection state: ESTABLISHED VSAN ID: 25 Table 21 Command output Field Description Local_ID:EXID/Local FC address and exchange ID of the local end.

Views VSAN view Predefined user roles network-admin Parameters fcid: Specifies the destination FC address of the static FC route, in the range of 0x010000 to 0xFFFFFF (hexadecimal). mask: Specifies a hexadecimal mask of the FC address. This argument is used together with the fcid argument. The value of this argument can be 0xFF0000, 0xFFFF00, or 0xFFFFFF. mask-length: Specifies a decimal mask of the FC address. This argument is used together with the fcid argument. The value of this argument can be 8, 16, or 24. interface-type interface-number: Specifies the outgoing interface of the static FC route, which must be an existing FC interface or VFC interface on the FC switch. cost cost-value: Specifies the cost of the route, in the range of 0 to 65535 and defaulting to 0. Usage guidelines Static routes are routes that are manually configured by an administrator. After an administrator configures a static route, an FC frame to the specified destination is forwarded along the static route. In a simple network, static routes are enough for implementing network connectivity. When the network fails or the network topology changes, you must manually modify the static routes. Static routes support equal-cost routes. When you configure multiple equal-cost static routes to the same destination but with different outgoing interfaces, equal-cost routes are generated. Examples # Add a static FC route: • The destination FC address is 0x010000.

• The outgoing interface is FC 1/0/1. • The cost is 20. system-view [Sysname] vsan 5 [Sysname-vsan5] fc route-static 010000 8 fc 1/0/1 cost 20 # Add a static FC route: • The destination FC address is 0x010000. • The mask length is 8. • The outgoing interface is VFC 4. • The cost is 20. system-view [Sysname] vsan 5 [Sysname-vsan5] fc route-static 010000 8 vfc 4 cost 20 Related commands display fc routing-table fspf cost Use fspf cost to configure the FSPF cost for the interface in a VSAN.

Use undo fspf hello-interval to restore the default. Syntax fspf hello-interval value vsan vsan-id undo fspf hello-interval vsan vsan-id Default The hello interval is 20 seconds. Views FC interface view, VFC interface view, FC aggregate interface view Predefined user roles network-admin Parameters value: Specifies the hello interval in the range of 1 to 65534 seconds. vsan vsan-id: Specifies the VSAN to which the interface belongs, in the range of 1 to 3839.

and maintain neighbor relationships. The configured hello interval must be smaller than the dead interval and must be the same at the two ends of the link. Examples # Configure the hello interval for interface FC 1/0/1 in VSAN 4 as 10 seconds. system-view [Sysname] interface fc 1/0/1 [Sysname-Fc1/0/1] fspf hello-interval 10 vsan 4 # Configure the hello interval for interface VFC 1 in VSAN 4 as 10 seconds. system-view [Sysname] interface vfc 1 [Sysname-Vfc1] fspf hello-interval 10 vsan 4 Related commands fspf dead-interval fspf min-ls-arrival Use fspf min-ls-arrival to configure the minimum LSR arrival interval for a VSAN. Use undo fspf min-ls-arrival to restore the default. Syntax fspf min-ls-arrival value undo fspf min-ls-arrival Default The minimum LSR arrival interval is 1 second. Views VSAN view Predefined user roles network-admin Parameters value: Specifies the minimum LSR arrival interval in the range of 0 to 60 seconds. Usage guidelines The minimum LSR arrival interval specifies the time between receiving LSRs in a VSAN. Any LSR instances of the same LSR received within this time are dropped. This helps avoid frequent SPF calculations caused by LSDB updating. Examples # Configure the minimum LSR arrival interval as 10 seconds for VSAN 2. system-view [Sysname] vsan 2 [Sysname-vsan2] fspf min-ls-arrival 10

Use undo fspf min-ls-interval to restore the default. Syntax fspf min-ls-interval value undo fspf min-ls-interval Default The minimum LSR refresh interval is 5 seconds. Views VSAN view Predefined user roles network-admin Parameters value: Specifies the minimum LSR refresh interval in the range of 1 to 60 seconds. Usage guidelines The minimum LSR refresh interval specifies the interval at which LSRs are refreshed. To reduce SPF calculations and LSR flooding in a fabric caused by frequent LSR refreshing, the switch cannot refresh local LSRs within this interval. Examples # Configure the minimum LSR refresh interval as 10 seconds for VSAN 2. system-view [Sysname] vsan 2 [Sysname-vsan2] fspf min-ls-interval 10 fspf retransmit-interval Use fspf retransmit-interval to configure the LSR retransmission interval for the interface in a VSAN. Use undo fspf retransmit-interval to restore the default. Syntax fspf retransmit-interval value vsan vsan-id undo fspf retransmit-interval vsan vsan-id Default The LSR retransmission interval is 5 seconds.
