show controllers cable-modem mac
Configuring the Cisco uBR900 Series Cable Access Routers 97
Example 5

The show controllers cable-modem mac state command summarizes the state of the cable MAC

layer and provides a list of downstream search frequency bands and the order in which they are

searched. 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.
