9.5 EVENTS AND ALARMS
The SmartSwitch 6500 switch records and reports its operation in real-time through the use of events and alarms. An
event is an occurrence of a significant activity. For instance, a port going down or a client joining an ELAN are
examples of events. Alarms are a specific class of events defined as "events that the user needs to know about or attend
to immediately." Alarms do not always indicate switch faults. Alarms may also be informational events. For instance,
"LECS Operational" is an example of an alarm that is not a switch fault, but is an activity that the user should know
about immediately.
