Troubleshooting Events and Alarms

Both events and alarms are stored within circular memory buffers. When the buffers become full, older events and alarms are overwritten by newer entries. Both events and alarms are stored in shared RAM. However, the 40 most recent alarms are also stored in flash RAM. Storing these 40 alarms in flash RAM makes them persistent between reboots of the ATM SmartSwitch, and provides information about the state of the switch prior to reboot.

Note Alarms are collected and stored in flash RAM in groups of four. As a result, some of the most recent alarms may not be persistent. For example, there are 24 (6 times

4)alarms stored in flash RAM. If a 25th alarm occurs, and the switch is rebooted, only the 24 alarms are persistent. The 25th alarm is dropped because the number of alarms (after 24) did not reached the next multiple of four (28).

Events are displayed in the following format:

•Event number — The index number of the event in the circular buffer

•Event ID — A unique ID assigned to the event

•Category — Whether this event is critical, major, minor, or informational

•Time — Time of event, in switch up-time in hours, minutes, seconds, and milliseconds

•Object — The object affected by the event (port, LEC, and so on)

•Description — Brief message describing the event

Event messages can be automatically displayed on the ATM SmartSwitch console. Use the set eventdisplay command to display events on the console as they occur:
