Pinging uses the Internet Control Message Protocol (ICMP) echo facility to send an ICMP echo request packet to the IP station you specify. It then waits for an ICMP echo reply packet. Possible responses from pinging:

■ Alive

■ No answer

■ Network is unreachable

A network is unreachable when there is no route to that network.

To ping an IP station:

1 From the top level of the Administration Console, enter:

ip ping

2Enter the IP address of the station you want to ping.

IP Address: 192.9.200.40

You may receive one of the following responses:

192.9.200.40 is alive

OR

no answer from 192.9.200.40

For a remote IP address, you can also receive the following response:
