Troubleshooting Tips for the Cisco uBR904 Cable Modem 31
Sample Display 4
This example display for the show controller cable-modem 0 mac hardware command shows the
detailed configuration of the interface driver and MAC layer hardware. The most interesting bit is
the station address (hardware address). The rest of the display is only of use to a software engineer.
The MIB statistics reflect the MAC hardware counters for various events, but these counters are
typically reset every few seconds, so their contents are not accurate in this display.
