Troubleshooting Routers

1-8

You can use the Technician Interface or Events Manager to combine the ﬁlters.

For example, you enter the following command to display all IP events from

11:19 on 1/22/96:

log -eIP -d01/22/96 -t11:19 -ffwtid

You can ﬁlter more than one software entity, slot number, and severity, and

combine ﬁlter types. The following example ﬁlters all severities from Ethernet

and IP running on Slots 3 and 4.

log -ffwtid -eCSMACD -eIP -s3 -s4

Refer to the following guides for more detailed information about using the event

log:

Understanding Debug Messages in the Event Log

One event severity type that raises many questions is Debug. Debug messages

help Bay Networks engineers troubleshoot problems. Many Debug messages refer

to lines of code and memory addresses that are meaningless to you. The Event

Messages for Routers and BNX Platforms manual does not describe the Debug

messages for this reason.

However, displaying the Debug messages can help you to understand the

systematic process the software uses to load and initialize discrete software

components when starting. And when the software detects a problem, the debug

messages can show you the systematic process the software uses to isolate its

components, shut them down, and restart them to try to ﬁx the problem.

Many debug messages are meaningless in isolation, but when considered in the

context of other messages, they can help you to understand the problem. Debug

messages typically contain words such as “creating,” “dying,” “killing,” “gates,”

and “gate handles.”

Note: Do not become alarmed at Debug messages. They appear routinely in

the log. Use the Fault, Warning, Info, and Trace message severities as your

primary ﬁlters for debugging problems before looking at the Debug messages.

By default, Site Manager and the Technician Interface do not display Debug

messages unless you use the Debug ﬁlter.
