Sample Display 5

The show controller cable-modem 0 mac state command summarizes the state of the cable MAC layer. If the cable MAC layer is in the wait_for_link_up_state, the information shown in the display corresponds to the last time the interface was up. This allows useful information to be acquired from this display even though the modem has not been able to range and register. The normal operational state of the interface is the maintenance_state.
