Steps to configure a log
1. Configure a log ID with a number from 1 to 98. 2. Identify the source.
3. Specify an optional filter to filter events if required. 4. Identify the destination.

Default Alarm Logs
There are two default and one special use log.
Log 99 – All severity levels of alarms
Log 100 – Only critical errors
Log 98 (special use) – Created by SAM managed nodes To view the logs, use the following commands:
show log log-id 99
show log log-id 100
More granular information in the two log files can be displayed by using:
show log log-id 99 subject 1/1/1 – port specific
show log log-id 99 application chassis – chassis-related alarms
Additional commands exist for displaying alarm information
Only store about 500 of the latest entries. If more entries are required, specific alarm logs need to be created
Showing Layer 1 and Layer 2 alarms
The 7750 SR and the 7450 ESS have two default memory logs (log-id 99 and log-id 100) that contain all of the events from the main application. All severity levels of alarms are recorded in log-id 99; log-id 100 only contains serious errors.
There are several ways to view the alarms of a specific subject, such as alarms related to a particular port. One method is to create a log that only monitors the specific subject.
Although Log 98 is not reserved or in use by default, it should be noted that the 5620 SAM network
management software will try to use this log-id by default. Generally it is recommended not to use log-id 98.

The show log log-id 99 application chassis command displays all alarms that are logged in the router. In the slide, the detailed information only displays minor alarms from the individual modules that are inserted in the chassis. From the time that appears in the slide, it appears that these entries are from when the router first booted.
