CMAC_LOG_RESET_NO_SEND_TO_DS_TUNER_PROCESS

The modem MAC layer process was unable to

 

 

 

communicate with the downstream tuner management

 

 

 

process.

 

 

 

 

 

CMAC_LOG_RESET_DS_TUNER_WATCHDOG

The downstream tuner process failed to report it's

 

 

 

continuing operation for a long period of time.

 

 

 

 

 

CMAC_LOG_RESET_UNABLE_TO_SET_MIB_OBJECT

The cable modem was unable to set an SNMP

 

 

 

parameter as specified by the DOCSIS configuration

 

 

 

file.

 

 

 

 

 

CMAC_LOG_RESET_MIB_OBJECT_PROCESS_WATCHDOG

The internal MIB object took to long to process the

 

 

 

entries in the DOCSIS configuration file.

 

 

 

 

 

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.
