AppleTalk: Interface Fails to Initialize AppleTalk
Possible Problems
Solution
Configuration
mismatch
1.
Use the
show appletalk interface exec
command. Check
the output for a “port configuration mismatch” message.
If the command output contains a “mismatch message,” the
router configuration disagrees with that of the listed neighbor.
If the command output does not include the “mismatch”
message, use the
clear apple interface privileged exec
command on the interface in question. If the interface becomes
operational after clearing, a configuration mismatch does not
exist.
2.
Enter the
show appletalk interface exec
command again.
If its output still contains a “port configuration mismatch”
message, check to see whether all router configurations
agree on network number or cable range and the zone or
zone list.
3.
If router configurations disagree on these parameters, alter
router configurations to bring all routers into alignment.
4.
If problems persist, put the problem router in discovery
mode by specifying the interface configuration command
appletalk address 0.0
on a nonextended network or the
appletalk cable-range 0-0
command on an extended
network. This causes the router to get its configuration
information from the network.
For more information about configuration mismatches, see the
section “AppleTalk Configuration Mismatches” earlier in this
chapter.
continues
Phase 1 and
Phase 2
rule violations
1.
Use the
show appletalk globals exec
command to
determine whether the internetwork is in compatibility
mode.
2.
Enable the
appletalk name-lookup-interval
global
configuration command and use the
show appletalk
neighbors exec
command to determine which specific
neighbor (by NBP name) is in compatibility mode.
3.
To resolve the problem, you can perform one of the
following actions:
•
Upgrade AppleTalk Phase 1 routers to AppleTalk Phase 2
and reconfigure the internetwork
•
Ensure that all routers are in compliance with the two
Phase 1 and Phase 2 rules
For more information on Phase 1 and Phase 2 rule violations,
see the section “Phase 1 and Phase 2 Rule Violations” earlier in
this chapter.
