SmartSwitch ATM Switch Reference Manual B-1APPENDIX B EVENT/ALARM MESSAGESThe SmartSwitch 2500 family and SmartSwitch 6500 record and report their operation in real-time using events andalarms. An event is the occurrence of a significant activity. Examples of events are a port going down or a client joiningan ELAN. Alarms are a specific class of events defined as “those events that the user needs to know about or attend toright away.” Alarms do not always indicate switch faults; for example, an alarm might indicate simply “LECS isoperational.” 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 areoverwritten by newer entries. Events are stored in shared RAM, while alarms are stored in flash RAM. That meansalarms are persistent between reboots of the SmartSwitch 2500 family and 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 canenable/disable automatic display of messages at the switch console.2põF Depending on the activity of your switch, the console may be flooded with eventmessages. Cabletron recommends that you enable the automatic display of eventmessages for troubleshooting purposes only.The following table lists switch commands used to manipulate log messages.Following is an example of the console display following a show events command:0 33554474 MAJOR EVENT 000:00:21:641---------------------------------------------------LES ReadServerConfig: Unable to open config file les.db1 117571585 MINOR EVENT 000:00:23:502---------------------------------------------------SAAL connection has become active, initiated locallyPort ID 0x00000002Protocol 0x022 33554656 MINOR EVENT 000:00:35:359---------------------------------------------------Sendto failed for IP address 206.61.231.153Table B-1 Event and Alarm CommandsCommand Descriptionshow events Displays the events currently logged.modify eventdisplay Enables/disables the automatic display of event messages on the console screen.show alarms Displays the alarms currently logged.modify alarmdisplay Enables/disables the automatic display of alarm messages on the console screen.
