Alarm Configuration

Using the Advanced Alarms feature, you can define custom alarms for almost any MIB-II or RMON object, as long as it is present in the device firmware and its value is defined as an integer (including counters, timeticks, and gauges). All aspects of these alarms are user-selectable: thresholds can be established on either the absolute or delta value for a variable; events can be configured to create a log, generate a trap, or both; and for Cabletron devices that support the new Actions MIB, events can also be configured to perform any defined SNMP SET or series of SETs on device objects. The Advanced Alarms feature also allows you to configure any events you wish to use in conjunction with the Packet Capture functionality. (For more information on using the Packet Capture feature, see the RMON User’s Guide included with your software.)

The Basic Alarms feature allows you to assign alarms to any interface type; using the Advanced Alarms feature, you need only be sure to select variables appropriate to the interface — Ethernet for Ethernet, Token Ring for Token Ring, etc. — when defining your alarms.

Basic Alarm Configuration

Using the Basic Alarm Configuration application, you can define both rising and falling alarm thresholds for three selected MIB-II objects: ifInOctets, ifInNUcast, and ifInErrors. Because these pre-selected objects are not RMON-specific, you can configure alarms for all interfaces installed in your MMAC-Plus chassis — including those, like FDDI, for which no specific RMON statistics currently exist.

In addition to configuring separate rising and falling thresholds, you can also configure your device’s response to an alarm condition: when a threshold is crossed, the RMON device can create a log of alarm events, send a trap notifying your management workstation that an alarm condition has occurred, or both; you can even configure an alarm to enable or disable bridging on the offending port in response to a rising or falling alarm condition.

If you are familiar with the RMON MIB and/or with the original Alarm and Event

TIP functionality provided by SPECTRUM Element Manager (now known as the Advanced Alarm functionality), you will note that the Basic Alarm Configuration window combines the three parts of creating a working alarm — configuring the alarm itself, configuring an event that will announce the occurrence of an alarm (including assigning any actions), and linking the two — into a single step, and handles the details transparently. For more information about the individual steps involved in creating an alarm, see Advanced Alarm Configuration, page 3-11.
