N Commands

This chapter describes the Cisco NX-OS Ethernet and virtual Ethernet commands that begin with N.

name (VLAN configuration)

To set the name for a VLAN, use the name command. To remove the user-configured name from a VLAN, use the no form of this command.

name vlan-name

no name

 
Syntax Description

vlan-name

Name of the VLAN; you can use up to 32 alphanumeric, case-sensitive characters. The default name is VLAN xxxx where xxxx represents four numeric digits (including leading zeroes) equal to the VLAN ID number (for example, VLAN0002).

 
Command Default

None

 
Command Modes

VLAN configuration mode

 
Command History

Release
Modification

4.0(0)N1(1a)

This command was introduced.

 
Usage Guidelines

You cannot change the name for the default VLAN, VLAN 1, or for the internally allocated VLANs.

Examples

This example shows how to name VLAN 2:

switch(config)# vlan 2
switch(config-vlan)# name accounting

Command
Description

show vlan

Displays VLAN information.

name (MST configuration)

To set the name of a Multiple Spanning Tree (MST) region, use the name command. To return to the default name, use the no form of this command.

name name

no name name

 
Syntax Description

name

Name to assign to the MST region. It can be any string with a maximum length of 32 alphanumeric characters.

 
Command Default

None

 
Command Modes

MST configuration mode

 
Command History

Release
Modification

4.0(0)N1(1a)

This command was introduced.

 
Usage Guidelines

Two or more switches with the same VLAN mapping and configuration version number are considered to be in different MST regions if the region names are different.

Caution Be careful when using the name command to set the name of an MST region. If you make a mistake, you can put the switch in a different region. The configuration name is a case-sensitive parameter.

Examples

This example shows how to name a region:

switch(config)# spanning-tree mst configuration
switch(config-mst)# name accounting
 

 
Related Commands

Command
Description

show spanning-tree mst configuration

Displays information about the MST protocol.

spanning-tree mst configuration

Enters MST configuration mode.

no switchport

To configure the interface as a Layer 3 Ethernet interface, use the no switchport command.

no switchport

 
Syntax Description

This command has no arguments or keywords.

 
Command Default

None

 
Command Modes

Interface configuration mode

 
Command History

Release
Modification

5.0(3)N1(1)

This command was introduced.

 
Usage Guidelines

You can configure any Ethernet port as a routed interface. When you configure an interface as a Layer 3 interface, any configuration specific to Layer 2 on this interface is deleted.

If you want to configure a Layer 3 interface for Layer 2, enter the switchport command. Then, if you change a Layer 2 interface to a routed interface, enter the no switchport command.

Examples

This example shows how to enable an interface as a Layer 3 routed interface:

switch(config)# interface ethernet 1/5
switch(config-if)# no switchport
switch(config-if)#
 

This example shows how to configure a Layer 3 interface as a Layer 2 interface:

switch(config)# interface ethernet 1/5
switch(config-if)# switchport
switch(config-if)#
