Appendix A:Troubleshooting a WSS 679
Nortel WLAN—Security Switch 2300 Series Configuration Guide
Running traces
Trace commands enable you to perform diagnostic routines. You can set a trace command with a keyword, such as
authentication or sm, to trace activity for a particular feature, such as authentication or the session manager.
Using the trace command
Tracing is used only for debugging WSS Software. The command set trace area enables you to view messages about the
status of a specific portion of the WSS Software.
There are many trace parameters that you can run. (See “List of trace areas” (page 682).) However, this chapter
describes only authentication, authorization, the session manager (sm), and 802.1X users (dot1x), four areas that you
might find most helpful.
To focus on the object of the trace, you can add one or more of these parameters to the set trace command:
set trace [area] [mac-addr mac-addr] [port port-num] [user username] [level level]
Tracing authentication activity
Tracing authentication activity can help you diagnose authentication problems. You can trace all authentication activity,
or only the activity for a specific user, MAC address, or port.
For example, to trace all authentication activity at level 4, type the following command:
WSS# set trace authentication level 4
success: change accepted.
Tracing session manager activity
You can trace all session manager commands, or only those for a specific user, MAC address, or port. For example, to
trace all session manager (sm) activity at level 3, type the following command:
WSS# set trace sm level 3
success: change accepted.
Tracing authorization activity
Tracing authorization activity can help diagnose authorization problems. For example, to trace the authorization of MAC
address 00:00:30:b8:72:b0, type the following command:
WSS# set trace authorization mac-addr 00:00:30:b8:72:b0
success: change accepted.
Caution! Using the set trace command can have adverse effects on system
performance. Nortel recommends that you use the lowest levels possible for initial trace
commands, and slowly increase the levels to get the data you need.
