9-10 CHAPTER 9: ADMINISTERING APPLETALK ROUTING

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 subnet to another

when required. When you disable IP forwarding, the router discards any

AppleTalk packets not addressed directly to one of its deﬁned interfaces.

1At the Administration Console’s top-level menu, enter:

appletalk forwarding

2Enter the slot(s) of the EFSM(s) for which you want to enable AppleTalk

forwarding.

3Enter enable or disable at the prompt.

Conﬁguring Checksum

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:

1At the Administration Console’s top-level menu, enter:

appletalk checksum

2Enter enable or disable at the checksum generation prompt.

3Enter enable or disable at the checksum veriﬁcation prompt.
