The Show controllers serial 0 command will show you whether either a DTE or DCE cable is connected to the interface. If it is a DCE connection, you need to add clocking with the clock rate command

Packets addressed to a multicast address are delivered to all interfaces identified with the multicast address, the same as in IPv4. It is also called a one-to-many address. You can always tell a multicast address in IPv6 because multicast addresses always start with FF.

The Command show mac address-table displays the forward/filter table on the switch.
