Hi,

Is it possible to disable one of the LAN ports on a 2920?
I've 3 ports in use. One connected to a locked Switch (so MAC filtering would be v difficult), so I'd like to lock down the spare ports on the 2920.

I expect I might be able to use the VLANs to do this.. but I think that would still give the "locked" port Internet access.

I don't think there is a way to turn 'off' unused PORTS on the 2920. I think your option is a work around such as 2nd VLAN, VERY explicit firewall rules (only certain IP's) or a physically locked chassis/cupboard.
