You can specify filters for more than one severity type. The Events Manager’s
Filter window allows you to select more than one filtering option, and the
Technician Interface allows you to specify more than one filter. The following
command displays all of the events:
log -ffwtid
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 10/29/97:
log -eIP -d10/29/97 -t11:19 -ffwtid
You can filter more than one software entity, slot number, and severity type, and
combine filter types. The following command filters all severity types from
Ethernet and IP running on slots 3 and 4.
log -ffwtid -eCSMACD -eIP -s3 -s4
See the following guides for detailed information about using the event log:
• Configuring and Managing Routers with Site Manager
• Using Technician Interface Software
• Event Messages for Routers
Understanding Debug Messages in the Event Log
The debug severity type often raises many questions. Debug messages help Nortel
Networks engineers troubleshoot problems. Many debug messages refer to lines
of code and memory addresses that are meaningless to you. For this reason, Event
Messages for Routers does not describe the debug messages.
Note:
Do not become alarmed at debug messages. They appear routinely in
the log. Use the fault, warning, informational, 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.
