Switch(config)# interface fastethernet0/2
Switch(config-if)#
This example shows how to change the management VLAN from the default management VLAN to
VLAN 3. This series of commands should only be entered from the service port. If these commands are
entered through a Telnet session, the shutdown command disconnects the session, and there is no way
to use IP to access the system.
Switch# configure terminal
Switch(config)# interface vlan 3
Switch(config-if)# ip address 172.20.128.176 255.255.255.0
Switch(config-if)# no shutdown
Switch(config-if)# exit
You can verify your settings by entering the show interfaces and show interfaces vlan vlan-id
privileged EXEC commands.
