Command History

Release
Modification

6.0(2)N1(1)

This command was introduced.


Usage Guidelines

You can specify a range of interfaces by entering a command with the following example format:

interface fc 1/1 - 5 , fc 2/5 - 7 
 
 

Use the no shutdown command to enable the interface.

The interface fc command enters interface configuration mode, which includes five commands (each with a no form). These five commands can only be used in the interface configuration mode.

The channel-group auto command enables autocreation of port channels. If autocreation of port channels is enabled for an interface, you must first disable this configuration before downgrading to earlier software versions or before configuring the interface in a manually configured channel group.

Examples

This example shows how to configure ports 1 to 4 in Fibre Channel interface 3:

switch(config)# interface fc 3/1 - 4
 
 

This example shows how to enable the Fibre Channel interface in port 1 of slot 3:

switch(config)# interface fc 3/1
switch(config-if)# no shutdown

Usage Guidelines

Before you use a virtual Ethernet interface, you must enable Cisco virtual machine feature on the switch by using the feature-set virtualization command.

You can create a maximum of 1000 virtual Ethernet interfaces on a Cisco Nexus 6000 switch. Before you disable the Cisco Adapter Fabric Extender (Adapter-FEX) on the switch, make sure that you delete these interfaces. After you delete a virtual Ethernet interface, make sure that you save the running configuration of the switch to the startup configuration file.

This example shows how to enter configuration mode for virtual Ethernet interface 10:

switch# configure terminal
switch(config)# interface vethernet 10
