CM Does Not Respond to SNMP Messages
Follow these steps to correct a CM that is not responding to SNMP messages:
1. To reset the CM so that it can respond to SNMP messages, use the clear cable
modem reset command in Privileged EXEC mode:
RDN#clear cable modem <MAC-address> reset
2. To reset all CMs so that they can respond to SNMP messages, use the clear
cable modem all reset command in Privileged EXEC mode, as shown in the
following example:
RDN#clear cable modem all reset
3. To verify that the clear cable modem all reset command enabled CMs to
respond to SNMP messages, enter the show cable modem command in
Privileged EXEC mode.
4. Make sure that the community names for SNMP Version 1 and SNMP
Version 2 and the user name for SNMP Version 3 are correct.
Note: Be sure to correctly enter the CM MAC address. It may take up to
30 seconds for the CM(s) to respond and start the reset sequence.
