Cisco IOS Release 12.2(15)CZ
The following example is a typical display for the show controllers cable-modem 0 mac hardware
command. The most interesting bit is the station address (hardware address). 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.
CMAC_LOG_RESET_T3_RETRIES_EXHAUSTED
The CMTS failed too many times to respond to a RNG-REQ
message.
Note After 16 T3 timeouts, the router resets the cable interface.
CMAC_LOG_RESET_RANGING_ABORTED
The CMTS commanded the router to abort the ranging process.
CMAC_LOG_RESET_NO_MEMORY
The router has run out of memory.
CMAC_LOG_RESET_CANT_START_PROCESS
The router was unable to start an internal process necessary to
complete ranging and registration.
CMAC_LOG_RESET_CONFIG_FILE_READ_FAILED
The reading of the configuration file from the TFTP server failed.
Note The file might not exist, or it might have incorrect
permissions.
CMAC_LOG_RESET_AUTHENTICATION_FAILURE
The router failed authentication as indicated in a REG-RSP message
from the CMTS.
CMAC_LOG_RESET_SERVICE_NOT_AVAILABLE
The CMTS has failed the router’s registration because a required or
requested class of service is not available.
CMAC_LOG_RESET_T6_RETRIES_EXHAUSTED
The CMTS failed too many times to respond to a REG-REQ
message.
CMAC_LOG_RESET_MAINTENANCE_WATCHDOG_DRIVER
The router MAC layer failed to detect a change in the interface
driver.
CMAC_LOG_RESET_NET_ACCESS_MISSING
The Network Access parameter is missing from the DOCSIS
configuration file.
CMAC_LOG_RESET_FAILED_WRITE_ACCESS_CONTROL
The router was unable to set the Write Access Control for an SNMP
parameter as specified by the DOCSIS configuration file.
CMAC_LOG_RESET_DHCP_FAILED
The DHCP server did not respond with all the required values. The
required values are: IP address, network mask, TFTP server IP
address, ToD server IP address, DOCSIS configuration filename,
and time zone offset.
CMAC_LOG_RESET_CANT_START_DS_TUNER_PRCESS
The router was unable to start the internal process used to manage
the downstream tuner.
CMAC_LOG_RESET_TOO_MANY_DS_LOCKS_LOST
Downstream QAM/FEC lock has been lost too many times.
CMAC_LOG_RESET_NO_SEND_TO_DS_TUNER_PROCESS
The router 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 its continuing
operation for a long period of time.
CMAC_LOG_RESET_UNABLE_TO_SET_MIB_OBJECT
The router 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 too long to process the entries in the
