CM> ping help

ERROR:  Invalid value for parameter IpAddress!  'help' Must be a valid IP 
Addr
ss!

COMMAND:  ping

USAGE:  ping  IpAddress

DESCRIPTION:
Pings the specified target IP address, sending 3 64-byte packets, and 
waiting
up to 5 seconds for a response.  This is a basic 'standard' ping.  For more
options or control over ping parameters and behavior.

In order for this to work, the CM must either have successfully completed
DHCP, or must otherwise have been configured with a valid IP address.

Note that this command causes the ping options to be reset to their default
state.

This may be disabled if the platform doesn't provide an implementation of
ping.

EXAMPLES:
ping 11.24.4.3  -- Ping IP address 11.24.4.3.
