Alarm Configuration

You can also access the Alarms function Ñ and the rest of the RMON functionality Ñ by

TIP selecting the RMON option from the Chassis View Utilities menu.

When the window is Þrst launched, no interfaces will be selected, and the Apply, Disable, and View Log buttons will be grayed out: the Apply and Disable buttons will activate when an interface is selected; the View Log button will activate when an interface which has experienced an alarm event is selected. The presence of an event log is indicated by the double greater-than sign (>>) displayed to the left of the threshold value that was crossed.

Viewing Alarm Status

The Basic Alarm ConÞguration window contains all the Þelds you need to conÞgure one or more of the three basic alarms available for each interface installed in your RMON device:

Kilobits — Total Errors — Broadcasts/Multicasts

Use these Þelds at the top of the window to change the alarm type whose status is displayed in the list box. For example, if the Kilobits option is selected, the information in the list box pertains to the status of the Kilobits alarm type for each installed interface. Before you conÞgure an alarm or alarms, be sure the appropriate option is selected here.

The available alarm variables are:

¥Kilobits (ifInOctets) Ñ tracks the number of octets of data received by the selected interface. Note that this value has been converted for you from octets (or bytes) to kilobits (or units of 125 bytes); be sure to enter your thresholds accordingly. For example, to set a rising threshold of 1250 octets, enter a threshold value of 10; to set a falling threshold of 625 octets, enter a threshold value of 5.

¥Total Errors (ifInErrors) Ñ tracks the number of error packets received by the selected interface.

¥Broadcast/Multicast (ifInNUcast) Ñ tracks the number of non-unicast Ñ that is, broadcast or multicast Ñ packets received by the selected interface.

Note that the three pre-selected alarm variables are all MIB II variables; this allows you to

TIP conÞgure alarms for any installed interface Ñ even those for which no speciÞc RMON statistics yet exist.
