I would suggest going into the interface of the unsused ports and shutting them down with the shutdown command. Ex. Console>en Console#config Console(config)#interface range ethernet e(1-5) Console(config-if)#shutdown That will disable ports 1-5.
This is a very newbie question. I am working on locking down my switches. I have managed to get HTTPS and SSH only access, but now I'm down to my last problem. How do I lock out un-used ports? I don't want anyone to be able to plug in and get access to my network.
