Step 3 Make sure that the VLAN is created by running the show vlan command.
3524XL#show vlan

Step 4 You may want to add the ports (interfaces) in the newly created VLAN. You have to go to interface configuration mode for each of the interfaces that you want to add into the new VLAN. Use the following set of commands in the privileged mode to add a particular interface in the VLAN.
3524XL#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
3524XL(config)#interface fastEthernet 0/2
3524XL(config-if)#switchport Access ?
vlan Set VLAN when interface is in access mode
3524XL(config-if)#switchport access vlan ?
VLAN ID of the VLAN when this port is in access mode
dynamic When in access mode, this interfaces VLAN is controlled by VMPS
3524XL(config-if)#switchport access vlan 2!-- Assigning interface fa0/2 to vlan 2
3524XL(config-if)#exit
3524XL(config)#interface fastEthernet 0/3
3524XL(config-if)#switchport access vlan 2!-- Assigning interface fa0/3 to vlan 2
3524XL(config-if)#end

Step 5 Verify VLAN configuration by using show vlan command.
3524XL#show vlan

1005 trnet 101005 1500 - - 1 IBM - 0 0
To remove ports from the VLAN, use the no switchport access vlancommand in the interface configuration mode. Once the port is removed from the VLAN that is not VLAN 1 (the default VLAN), that port is automatically added back to the default VLAN.
For example, if you want to remove interface Fa0/2 from cisco_vlan_2 (VLAN 2), use the following set of commands in the privileged mode:
3524XL#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
3524XL(config)#interface fastEthernet 0/2
3524XL(config-if)#no switchport access vlan 2!
-- Removing interface fa0/2 from vlan 2
3524XL(config-if)#end
