SmartSwitch 6500 Reference Manual B-1
APPENDIX B EVENT/ALARM MESSAGES
The SmartSwitch 6500 records and reports its operation in real-time using events and alarms. An event is the
occurrence of a significant activity. Examples of events are a port going down or a client joining an ELAN. Alarms are
a specific class of events defined as “those events that the user needs to know about or attend to right away.” Alarms
do not always indicate switch faults; for example, an alarm might indicate simply “LECS is operational.” Notice also
that some switch activities are reported both as events and alarms.
Event and alarm messages are saved in circular memory buffers. When the buffers are full, older events and alarms are
overwritten by newer entries. Events are stored in shared RAM, while alarms are stored in flash RAM. That means
alarms are persistent between reboots of the SmartSwitch 6500, while events are not.
Event and alarm buffers are called the event and alarm logs. In addition to viewing the messages in the logs, you can
enable/disable automatic display of messages at the switch console.
2 p›F
Depending on the activity of your SmartSwitch 6500, the console may be flooded
with event messages. Cabletron recommends that you enable the automatic
display of event messages for troubleshooting purposes only.
The following table lists switch commands used to manipulate log messages.
