Using ping 119
The following are possible responses to a ping:
■ If the host is reachable, the Layer 3 Module displays information about
the ICMP reply packets and the response time to the ping. The
amount of information depends on whether the quiet option is
enabled or disabled.
■ If the host does not respond, the Layer 3 Module displays the ICMP
packet information and the message,
Host is Not Responding.
■ If the packets cannot reach the host, the Layer 3 Module displays the
ICMP packet information and the message,
Host is Unreachable.
A host is unreachable when there is no route to that host.
