AppleTalk: Zones Missing from Chooser (continued)
Possible Problems
Solution
Too many zones in
internetwork
The Chooser in System 6 can display only a limited number of
zones, which presents problems in large internetworks that have
many zones.
If the Macintosh is running a version of System 6, upgrade it to
System 7 or System 7.5.

RTMP = Routing Table Maintenance Protocol
AppleTalk: No Devices in Chooser
Symptom:
Zones appear in the Chooser, but when a service (such as AppleShare) and a zone are
selected, no devices appear in the device list.
Table 9-5 outlines the problem that might cause this symptom and describes solutions to that problem.
Table9-5
AppleTalk: No Devices in Choose
Possible Problems
Solution
Misconfigured
access lists
1.
Use the
show appletalk access-list exec
command on
routers in the path from source to destination.
2.
Disable any access lists (or just those on a particularly
suspect router) using the
no appletalk access-group
interface configuration command.
3.
After disabling access lists, check whether devices appear
in the Chooser.
4.
If devices now appear in the Chooser, a misconfigured
access list is probably filtering NBP traffic. To isolate the
problem access list, enable lists one at a time until devices
no longer appear.
5.
Check the access lists and associated configuration
commands for errors. Configure explicit
permit
statements
for traffic that you want to pass through the router normally.
6.
If problems persist, there might be more than one
misconfigured access list. Continue enabling access lists
one at a time and fixing misconfigured access lists until the
problem is solved.
For detailed information about filtering NBP traffic using
access lists, refer to the Cisco IOS
