Command Reference Table 6 Possible but Uncommon Cable Interface Reset Causes (Continued) Message CMAC_LOG_RESET_DHCP_FAILED CMAC_LOG_RESET_CANT_START_DS_TUNER_PRCESS CMAC_LOG_RESET_TOO_MANY_DS_LOCKS_LOST CMAC_LOG_RESET_NO_SEND_TO_DS_TUNER_PROCESS CMAC_LOG_RESET_DS_TUNER_WATCHDOG CMAC_LOG_RESET_UNABLE_TO_SET_MIB_OBJECT CMAC_LOG_RESET_MIB_OBJECT_PROCESS_WATCHDOG Description 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 file name, and time zone offset. The cable modem was unable to start the internal process used to manage the downstream tuner. Downstream QAM/FEC lock has been lost too many times. The cable modem MAC-layer process was unable to communicate with the downstream tuner management process. The downstream tuner process failed to report its continuing operation for a long period of time. The cable modem was unable to set an SNMP parameter as specified by the DOCSIS configuration file. The internal MIB object took too long to process the entries in the DOCSIS configuration file. Example 4 The following example display for the show controllers 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 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. uBR904# show controllers cable-modem 0 mac hardware PLD VERSION: 32 BCM3220 unit 0, idb 0x200EB4, ds 0x82D4748, regaddr = 0x800000, reset_mask 0x80 station address 0010.7b43.aa01 default station address 0010.7b43.aa01 MAC mcfilter 01E02F00 data mcfilter 01000000 buffer size 1600 RX data PDU ring with 32 entries at 0x201D40 rx_head = 0x201D40 (0), rx_p = 0x82D4760 (0) 00 pak=0x82DF844 buf=0x227F1A status=0x80 pak_size=0 01 pak=0x82E0BF4 buf=0x22C56A status=0x80 pak_size=0 02 pak=0x82DF454 buf=0x22710A status=0x80 pak_size=0 03 pak=0x82DF64C buf=0x227812 status=0x80 pak_size=0 04 pak=0x82E0024 buf=0x229B3A status=0x80 pak_size=0 05 pak=0x82DBF2C buf=0x21B332 status=0x80 pak_size=0 06 pak=0x82DFE2C buf=0x229432 status=0x80 pak_size=0 07 pak=0x82E0FE4 buf=0x22D37A status=0x80 pak_size=0 08 pak=0x82DF064 buf=0x2262FA status=0x80 pak_size=0 09 pak=0x82DEC74 buf=0x2254EA status=0x80 pak_size=0 10 pak=0x82DEA7C buf=0x224DE2 status=0x80 pak_size=0 11 pak=0x82DE884 buf=0x2246DA status=0x80 pak_size=0 12 pak=0x82DE68C buf=0x223FD2 status=0x80 pak_size=0 13 pak=0x82DE494 buf=0x2238CA status=0x80 pak_size=0 14 pak=0x82DE29C buf=0x2231C2 status=0x80 pak_size=0 15 pak=0x82DE0A4 buf=0x222ABA status=0x80 pak_size=0 16 pak=0x82DDEAC buf=0x2223B2 status=0x80 pak_size=0 17 pak=0x82DDCB4 buf=0x221CAA status=0x80 pak_size=0 36 Cisco IOS Release 12.0(3)T
