Vlan Command on CISCO Router/Switch

Command

Vlan

Use

This is the modern way to configure VLANs. A useful feature of this command is that you can configure a range of VLANs with a single command.

Syntax

Switch(config)#vlan <vlan range>

Options

Example

In the below example we will configure VLAN 25 and name it MANAGEMENT.

Cat1(config)#vlan 25
Cat1(config-vlan)#name MANAGEMENT
Cat1(config-vlan)#exit
Cat1(config)#do show vlan brief

VLAN Name Status Ports
—- ——————————– ——— ——————————-
1 default active Fa0/1, Fa0/2, Fa0/3, Fa0/4
Fa0/5, Fa0/6, Fa0/7, Fa0/8
Fa0/9, Fa0/10, Fa0/11, Fa0/12
Fa0/13, Fa0/14, Fa0/15, Fa0/16
Fa0/17, Fa0/18, Gi0/2
25 MANAGEMENT active
1002 fddi-default act/unsup
1003 token-ring-default act/unsup
1004 fddinet-default act/unsup
1005 trnet-default act/unsup

Now we will configure a VLAN range to configure many VLANs at once.

Cat1(config)#vlan 55-70,101-103
Cat1(config-vlan)#exit
Cat1(config)#do show vlan brief
