Trying to see the MAC address table on a Cisco switch is a pain because issuing the "show ?" command should show you all of the show commands that can be issued. But it looks like its not all of the commands that can be given because at least one does not show up. Even in enable mode the command "show mac-address-table" does not come up. But it's a valid and helpful command. If you want to track down a rougue device that was plugged into your network and find its MAC address to trace it back to the patch panel you need to see the MAC address that are attached to the ports of each switch. If you hit an uplink port of the MAC address you looking for then follow it to the next switch plugged into that switch. Keep doing this until you find the switch that has the MAC address locally and match it to the patch panel.
