Managing Ethernet MicroLAN Switches

5-14 Alarm Limits

Alarm Limits

Using the Alarm Limits windows, you can conÞgure alarm limits for the Ethernet

MicroLAN Switch at the repeater, board, and port levels; these alarms will notify

you Ð via traps sent to SPECTRUM Element ManagerÕs alarm logging facility Ð

that your system has experienced a certain percentage of collisions or errors, or a

certain number of speciÞc packet types, within a user-deÞned 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 Repeater on the Chassis View menu bar; a menu listing the available

repeater channels will appear.

2. Select the appropriate repeater channel (A - H) to reveal the Repeater menu.

3. Click on Alarm Limits. The Repeater Alarm Limits window, Figure 5-6, will

appear.

NOTE

In order for your device to issue any traps Ð and in order for your management

workstation to receive those traps Ð your Ethernet MicroLAN SwitchÕs trap table must

have been properly conÞgured via Local Management; see the Ethernet MicroLAN Switch

hardware manual for more information.

TIP

Although you can access the Alarm Limits window at both the repeater and board levels,

note that setting alarms at those two levels will have the same effect, as each Ethernet

MicroLAN Switch ÒboardÓ is equivalent to a repeater channel.
