• To duplicate a CM certificate to provisioned certificate table, use the cable
privacy provision-cert-add command in Privileged EXEC mode as shown
below:
MOT(config)#cable privacy provision-cert-add {<mac>}
where:
mac is the MAC address.
Pinging a Cable Modem at the MAC Layer
The ping DOCSIS command is used to “ping” or find a cable modem (CM) on the
network at the MAC layer by entering the CM’s MAC or IP address.
When a DOCSIS ping is initiated, the BSR sends a test packet downstream towards
the CM to test its connection. In most instances, this command is used to determine if
a particular CM is able to communicate at the MAC address layer when a cable
modem has connectivity problems at the network layer. For example, if a CM is
unable to register and obtain an IP address, the ping DOCSIS command can help you
determine if there are provisioning problems associated with the CM.
Follow these steps to use the ping DOCSIS function:
1. To specify the number of DOCSIS ping packets, use the ping docsis size
command in Privileged EXEC mode, as shown below:
MOT#ping docsis size <n>
where:
n is the number of ping test packets directed toward a CM.
2. To enter Global Configuration mode, use the config command in Privileged
EXEC mode.
3. To enter the cable interface, use the interface cable command in Global
Configuration mode.
