I have a question on CATOS that I am sad to ask. I have a command set on an interface:
set vlan 203 3/4
How can I undo this command? I know this is a silly question but I cannot find reference anywhere! Thanks.
The ports have to be in some vlan and there is no option other than to configure it as a trunk. By default on all cisco switches ports are assigned to vlan 1 which can be changed but cannot be removed completely.
What you can do is just change the vlan assignment for that port.
set vlan 1 3/4
When you issue this command this port will move to vlan 1 which is default setting for any layer 2 port on cisco switches or your option is to configure this port as trunk.
Can you explain what exactly is your requirement and why you want the port not to be in any vlan?
