Command
Vlan
Use
This is the legacy way to configure VLANs on a switch. While this mode is being depreciated, you will still encounter it on older switches or routers with switch modules. On newer IOS releases, VLANs are configured in configure mode.
Syntax
Switch(vlan)#vlan <number>
OR
Switch(vlan)#vlan <number> name <vlan_name>
Example
In the below example we will enter the VLAN database, configure VLAN 55 and name it MANAGEMENT. First, we will verify that only the default VLANs are configured on the switch.
2950-XL#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, Fa0/19, Fa0/20, Fa0/21, Fa0/22, Fa0/23, Fa0/24 1002 fddi-default active 1003 token-ring-default active 1004 fddinet-default active 1005 trnet-default active
Now we will create the vlan and name it. It is importent that when you create a vlan in the vlan database you either type apply or exit. If you don’t, then your changes will not be saved.
2950-XL#vlan database 2950-XL(vlan)#vlan 55 name MANAGEMENT VLAN 55 added: Name: MANAGEMENT 2950-XL(vlan)#exit APPLY completed. Exiting….
A show vlan brief confirms that vlan was created.
