Which command would you use to diagnose a problem with frames that are not getting forwarded to the destination node on a switch?

When you're diagnosing frame forwarding on a switch, the MAC address table needs to be inspected to see if the switch has learned the destination MAC address. You can use the command show mac address-table to inspect the MAC address table. The command show route is incorrect; it only displays layer 3 route decision information. The command show mac table is incorrect. The command show interface is also incorrect; it will not display information on how the switch will make forward/filter decisions.
