Managing Ethernet MicroLAN Switches

Setting Alarm Limits

To set repeater-, board-, or port-level alarms, first be sure you have opened the appropriate Alarm Limits window, then follow the steps outlined below:

1.Using the mouse, click and drag to highlight the text box in the alarm field you wish to configure (Collisions, Packets, Broadcast Packets, or % Errors).

2.Enter the desired threshold value, being sure to keep in mind the units and range limits described above.

3.Click on the Enable Alarm check box to activate it. (A check box is activated if there is an check in it.)

4.For board- or port-level alarms only, click on the Allow Board/Port to be Disabled on Alarm check box if you wish to disable the board or port when an alarm condition occurs.

NOTES

If you activate the Allow Board/Port to be Disabled on Alarm option, you will have to manually re-enable the board(s) or port(s) if the alarm is triggered. Resetting the device will clear the condition by clearing all packet counters, but you will still need to re-enable the board(s) and/or port(s). On an Ethernet MicroLAN Switch, a board is equivalent to a repeater channel; use care when selecting the Allow Board to be Disabled on Alarm option.

5.Repeat steps 1-4 for each type of alarm you wish to configure.

6.Click on the Apply button to save the configuration, then click the Cancel button to close the window. Be sure to click on the Apply button before closing the window, or your changes will not be saved.

Your Alarm Limits are now set. Any condition that exceeds these alarm limits will generate an alarm, and disable that board or port, if so configured. Refer to the Alarm and Event Handling Guide for information on how to use the alarm logging facilities to view alarms.

Trap Selection

Cabletron and Enterasys devices are designed to generate traps which indicate when a repeater port gains or loses a link signal (Link State Traps); when the repeater segments (disconnects) a port due to collision activity, and when a segmented port becomes active again (Segmentation Traps); and several traps that result from changes in a port’s Source Address Table (Source Address Traps). In some networks, these traps may impart more information than a network manager wants to see. With the Trap Selection option available from the Repeater, Board, and Port menus, you can selectively enable and disable these traps.

Any traps issued by the Ethernet MicroLAN Switch displays in NetSight Element Manager’s alarm logging facility. (Refer to your Alarm and Event Handling Guide for more details.)
