Usage Guidelines

This ping is a MAC layer ping that uses extra keep-alive poll messages. It also uses smaller data units

than a standard IP ping, which reduces the overhead. It will work even if the IP layer in the modem

is down or not fully registered.

Example

The following example conﬁrms that the cable modem at 172.00.00.00 is connected to the network

and is operational:

Router# ping cable-modem 172.00.00.00

172.00.00.00 is alive

mac-addr Cable modem IP address.
