Checksum is a simple method used for detecting errors in the transmission
of data. Checksum generation totals the bytes comprising the data and
adds this sum to the end of the data packet. Checksum verification allows
you to verify the integrity of the data that is routed. You can enable or
disable checksum generation and verification states.
To enable or disable checksum generation/verification:
1 At the Administration Console's top-level menu, enter:
appletalk checksum
2 Enter or
enable disable
3 Enter or
enable disable
The AppleTalk Echo Protocol (AEP) sends a datagram (an Echo Request)
from one node to another, which causes the destination node to return or
echo, the datagram (an Echo Reply) to the sender. This allows you to
determine whether a node is accessible before any sessions are started.

1 At the Administration Console's top-level menu, enter:
appletalk ping

2 Enter the address of the node you want to ping.
