AppleTalk Configuration and Troubleshooting Tips
This section offers configuration and troubleshooting tips that can help you prevent or more easily
repair problems in AppleTalk internetworks.
It consists of information on preventing AppleTalk problems, preventing internetwork
reconfiguration problems, changing zone names, using AppleTalk Discovery Mode, and forcing an
interface up to allow a router to start functioning if the network is misconfigured.
Preventing AppleTalk Problems
Table 9-1 lists suggestions to help you avoid problems when configuring a router for AppleTalk.
Table 9-1 AppleTalk Problem-Prevention Techniques
Preventive Action Description
Every router connected to a
network must agree on the
configuration of that
network
Every router on an AppleTalk network (that is, on a single cable segment) must agree
on the configuration of the network. Therefore, network numbers, cable ranges, timer
values, zone names, and other parameters should be the same for every router on the
segment.
Every network number in an
internetwork must
be unique
Network numbers must be unique throughout the entire AppleTalk network. Duplicate
network numbers can cause connectivity- and performance-related problems.
Upgrade to AppleTalk
Phase 2 wherever possible
To minimize interoperability problems, upgrade all router Ethernet interfaces to
Phase 2. Phase 1/Phase 2 networks can be problematic, as can nonextended AppleTalk
networks.
