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.
Accessing the Alarm Limits Windows
To open the repeater-level Alarm Limits window from the Chassis View:
1. Click on R
epeater on the Chassis View menu bar to reveal the Repeater
menu.
2. Drag down to A
larm Limits... and release. The Repeater Alarm Limits
window, Figure 5-1, will appear.
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.
