Configuring
Forwarding
You can control whether the router forwards or discards AppleTalk
packets addressed to other hosts. When you enable forwarding, the
router processes packets as usual, forwarding AppleTalk packets from one
subnetwork to another when required. When you disable AppleTalk
forwarding, the router discards any AppleTalk packets not addressed
directly to one of its defined interfaces.
To configure AppleTalk forwarding:
1
From the top level of the Administration Console, enter:
appletalk forwarding
2
At the prompt, enter
enabled
or
disabled
Configuring
Checksum
AppleTalk uses checksums to detect errors in data transmissions. A
checksum totals all data bytes and adds this sum to the end of the data
packet. The receiving station computes a verification checksum from the
incoming data and compares the new checksum with the value sent with
the data. If the values do not match, the transmission contains an error.
You can enable or disable checksum generation and verification.
To enable or disable checksum generation/verification:
1
From the top level of the Administration Console, enter:
appletalk checksum
2
At the checksum generation prompt, enter
enabled
or
disabled
3
At the checksum verification prompt, enter
enabled
or
disabled
