Well, that would also stop you from accessing the switch 
remotely, since Management tends to be done over IP :-).

Later IOS-based Cisco Catalyst switches, which support IP 
routing and forwarding, can be told to operate a port in 
either Layer 2 or Layer 3 mode (the 'switchport' command).

Earlier boxes like the 4908 (the device in question re: this 
thread) seem to live by their own rules. Refer to the link I 
posted earlier.

Cheers,

Mark.
