B Commands

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

bind

To bind an interface to a virtual Fibre Channel interface, use the bind command. To remove the binding of an interface, use the no form of this command.

bind interface {ethernet chassis-id/slot/port | port-channel channel-no | vethernet veth-num}

no bind interface {ethernet chassis-id/slot/port | port-channel channel-no | vethernet veth-num}

Syntax Description

interface

Specifies the interface to bind the virtual Fibre Channel interface.

ethernet

Specifies that the virtual Fibre Channel interface be bound to a specified Ethernet interface.

chassis-id

Fabric Extender chassis ID. The chassis ID range is from 100 to 199.

slot/port

Ethernet interface slot number and port number. The slot number is from 1 to 255 and the port number is from 1 to 128.

Note When you bind an interface to a virtual Fibre Channel interface to enable Fibre Channel over Ethernet (FCoE) traffic on a Cisco Nexus 2232P Fabric Extender, the slot number is 1 and the port number is from 1 to 32.

port-channel channel-no

Specifies that the virtual Fibre Channel interface be bound to a specified EtherChannel interface. The EtherChannel number is from 1 to 4096.

vethernet veth-num

Specifies that the virtual Fibre Channel interface be bound to a specified virtual Ethernet interface. The virtual Ethernet interface number is from 1 to 1048575.

Modification

4.0(0)N1(1a)

This command was introduced.

5.0(2)N1(1)

The bind, description, and shutdown commands were separated from the interface vfc command.

5.1(3)N1(1)

Support for this command was extended to allow binding of a member port of a port channel.

Support for this command was added for the Cisco Adapter Fabric Extender (Adapter-FEX).


Usage Guidelines

The Ethernet or EtherChannel interface that you bind to the virtual Fibre Channel interface must be a trunk port.

Before you bind a virtual Fibre Channel interface to a virtual Ethernet interface, you must enable the Cisco Adapter Fabric Extender (Adapter-FEX) on the switch by using the feature-set virtualization command.

Examples

This example shows how to bind a virtual Fibre Channel interface 3 to an Ethernet interface: 

switch# configure terminal

switch(config)# interface ethernet 1/1

switch(config-if)# switchport mode trunk

switch(config-if)# exit

switch(config)# interface vfc 3

switch(config-if)# bind interface ethernet 1/1

switch(config-if)# 

 
   
 
    
   
 This example shows how to bind a virtual Fibre Channel interface 2 to a virtual Ethernet interface: 
 
    
   
 
    
switch# configure terminal

 
   
 
    
   
 
    
switch(config)# interface vfc 2

 
   
 
    
   
 
    
switch(config-if)# bind interface vethernet 100

 
   
 
    
   
 
    
switch(config-if)# exit

 
   
 
    
   
 
    
switch(config)# interface vethernet 100

 
   
 
    
   
 
    
switch(config-if)# bind interface ethernet 101/1/1 channel 5
