Troubleshooting the CMTS

4-71

1. To ping a specific CM IP address or hostname to determine if the CM is

online, use the ping command in Privileged EXEC mode, as shown in the

following example:

RDN#ping {<ip-address> | <hostname>}

where:

ip-address is the IP address of the CM

hostname is the DNS hostname of the CM

2. If there is no IP level conectivity, but you suspect the CM has connectivity at

the MAC layer, use the ping docsis command in to ping a specific CM at the

MAC layer:

RDN(config-if)#ping docsis [<mac-address> | <ip-address>]

3. Determine if the CM is having registration problems by using the debug cable

reg command in Interface Configuration mode, as shown in the following

example:

RDN#debug cable reg

4. To reset a specific CM by using its MAC address, use the clear cable modem

reset command in Privileged EXEC mode, as shown in the following

example:

RDN#clear cable modem [<MAC-address> | <ip-address>] reset

where:

Note: You must use a IP address for the CM you are pinging. If you

cannot ping the CM using its IP address, the CM is not registering.

Note: Be sure to use the correct MAC or IP address of the CM.
