Pinging an AppleTalk Node 14-11

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:

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.

You can view statistics for the following AppleTalk protocols:

■

Datagram Delivery Protocol (DDP)

■

Routing Table Maintenance Protocol (RTMP)

■

Zone Information Protocol (ZIP)

■

Name Binding Protocol (NBP)

To display DDP statistics, from the top level of the Administration
