Pinging an AppleTalk Node
14-11
Pinging an
AppleTalk Node
The AppleTalk Echo Protocol (AEP) sends a datagram (an Echo Request)
from one node to another. The destination node returns, or
echoes
, the
datagram to the sender (using an Echo Reply). This process allows you to
determine whether or not a node is accessible before starting a session.
To ping an AppleTalk node:
1
From the top level of the Administration Console, enter:
appletalk ping
The system prompts you for a node address.
2
Enter the address of the node you want to ping.
If the node is accessible, you receive a response.
