Configuring Vlan on Cisco Switch

Introduction to VLAN

You can configure VLANs on Cisco Catalyst switch by using vlan command on the global configuration mode.

Remember, VLAN 1 is the administrative VLAN.

Swtich#config terminal

Switch(confing)#vlan 2
Switch(config-vlan)#name freetechexams
Switch(config-vlan)#vlan 3
Switch(config-vlan)#freetechexams1
Switch(config-vlan)#vlan 4
Switch(config-vlan)#freetechexams2
Switch(config-vlan)#^Z

Switch#

From the above configurations, 3 VLANs are created with the name of freetechexams, freetechexams1 and freetechexams2. VLANs can be created from 2 to 4094. VLAN 1 is reserved and created by default.

You can check the list of created VLANs by using Show vlan command.

Switch# Show vlan

A VLAN is useless if you have not assigned specific ports to a VLAN. You can add specific ports to a VLAN by using following steps

Switch# config t
Switch(config)# int fa0/3
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 3
