Alarm Limits

Accessing the repeater, board, and port Alarm Limits windows; setting alarm limits based on percentage of collisions, packet count, broadcast packet count, or percentage of errors; setting the alarm limits time interval; using the Disable Board/Disable Port on Alarm option

Using the Alarm Limits windows, you can configure alarm limits for the IRM2 at the repeater, board, and port levels; these alarms will notify you — via traps sent to your Enterasys management application’s alarm logging facility — that your system has experienced a certain percentage of collisions or errors, or a certain number of specific packet types, within a user-defined time interval. You can also use the board- and port-level Alarms windows to disable a board or port in response to an alarm condition.

NOTE

In order for your device to issue any traps — and in order for your management workstation to receive those traps — your IRM2’s trap table must have been properly configured via Local Management; see the IRM2 hardware manual for more information.

1.Click on Repeater on the Chassis View menu bar to reveal the Repeater menu.
