Troubleshooting Other Network Layer Protocols
This section assumes that you have isolated a problem to a network layer protocol.
If not, refer to Chapter 2 to determine whether these instructions apply to your
problem.
Troubleshoot other network layer protocols as follows:
1.
Use the Events Manager or the Technician Interface to filter the log to
display messages of all severity levels for the protocol in question.
The Technician Interface command is as follows:
log -fftwid -e
<ENTITY>
-s
<slot_no.>
When specifying
<ENTITY>
, use uppercase letters. See Event Messages for
Routers for a list of the entities.
Example
If you are filtering events from the XNS, entity running in slots 3 and 4, enter
the following command:
log -fftwid -eXNS -s3 -s4
2.
Check the base records.
For example, if you are having a problem with XNS, enter
get
wfXnsBase.*.0
to check the status of the software.
The most important attributes are as follows:
• The State attribute shows whether the protocol is up (1), down (2),
initializing (3), or not present (4). You cannot change this setting.
• The Create or Delete attribute shows whether the network software is
created (1) or deleted (2).
• The Enable or Disable attribute shows whether the protocol is enabled (1)
or disabled (2).
