V Commands

This chapter describes the Cisco NX-OS Fibre Channel, virtual Fibre Channel, and Fibre Channel over Ethernet (FCoE) commands that begin with V.

vsan

To create multiple fabrics sharing the same physical infrastructure, assign ports to Virtual SANs (VSANs), turn on or off interop mode, load balance either per originator exchange or by source-destination ID, and VSAN membership, use the vsan command. To remove a configuration, use the no form of this command.

Syntax Description

vsan vsan-id

Specifies the VSAN ID. The range is from 1 to 4094.

interface fc slot / port

(Optional) Specifies the Fibre Channel interface by slot and port number on the switch.

san-port-channel port

Configures the SAN port channel interface specified by the SAN port channel number.

vfc vfc-id

Specifies the virtual Fibre Channel interface.

interop

(Optional) Turns on interoperability mode.

mode

(Optional) Interop mode. The range is from 1 to 4.

loadbalancing

(Optional) Configures the load balancing scheme.

src-dst-id

Sets src-id/dst-id for load-balancing.

src-dst-ox-id

Sets ox-id/src-id/dst-id for load balancing (default).

name name

Assigns a name to the VSAN. The name can be a maximum of 32 characters.

suspend

Suspends the VSAN.

 
Command Default

None

Usage Guidelines

To use this command, change to the VSAN database mode.

The interface range must be in ascending order and nonoverlapping. You can specify a range using a hyphen and several interfaces using commas:

  • The interface range format for a Fibre Channel interface range is

fcslot/port - port, fcslot/port, fcslot/port:

For example, show int fc2/1 - 3, fc2/4, fc3/2

  • The format for a SAN port channel is

san-port-channel portchannel-number.subinterface-number:

For example, show int san-port-channel 5.1

There are four interop modes:

  • Interop mode 1 — Standards based interop mode that requires all other vendors in the fabric to be in interop mode.
  • Interop mode 2 — Brocade native mode (Core PID 0).
  • Interop mode 3 — Brocade native mode (Core PID 1).
  • Interop mode 4 — McData native mode. Before you configure Interop mode 4 (or remove the configuration), you must suspend the VSAN. You should unsuspend the VSAN only after you configure a VSAN-dependent switch WWN with the McData OUI [08:00:88].

The no form of the vsan vsan-id interface command is not supported. To remove a VSAN membership of an interface (for example, interface fc1/8 from VSAN 7), you must assign the interface to another VSAN. The best practice is to assign the interface back to the default VSAN (VSAN 1).

Examples

This example shows how to create multiple fabrics sharing the same physical infrastructure and how to assign ports to VSANs:

switch(config)# vsan database
switch-config-vsan-db# vsan 2
switch(config-vsan-db)# vsan 2 name TechDoc
switch(config-vsan-db)# vsan 2 loadbalancing src-dst-id
switch(config-vsan-db)# vsan 2 loadbalancing src-dst-ox-id
switch(config-vsan-db)# vsan 2 suspend
switch(config-vsan-db)# no vsan 2 suspend
switch(config-vsan-db)# end
 

This example shows how to suspend a VSAN and enable Interop mode 4:

switch(config)# vsan database
switch(config-vsan-db)# vsan 100 suspend
switch(config-vsan-db)# vsan 100 interop 4
switch(config-vsan-db)# exit
 

This example shows how to configure a VSAN to create a FCOE-VLAN to VSAN mapping:

switch(config)# vsan database
switch(config-vsan-db)# vsan 377
switch(config-vsan-db)# exit
switch(config)# vlan 30
switch(config-vlan)# fcoe vsan 337
switch(config-vlan)#
 

This example shows how to remove interface fc2/1 from VSAN 7:

switch(config)# vsan database
switch(config-vsan-db)# vsan 1 interface fc2/1
switch(config-vsan-db)#
