Creating RMON alarms

To create an alarm using default values and to receive statistics and history:

1. Make sure that RMON is globally enabled.

When you enable RMON globally, you also create a default rising and falling event. The default for the events is log-and-trap, meaning you will receive notification through a trap as well as through a log file.

2. From the Device Manager menu bar, choose RMON > Alarm Manager.

The Alarm Manager dialog box opens.

3. In the Variable field, select a variable for the alarm and a port (or other ID) on which you want to set an alarm.

Alarm variables are in three formats, depending on the type:

• A chassis, power supply, or fan-related alarm ends in x where the x index is hard-coded. No further information is required.
• A card, RIP or OSPF, or EtherStat alarm ends with a dot (.). You must enter a card number, IP address, or EtherStat information.
• A port alarm requires a port ifindex. For example, when you select a port alarm for ifInOctets (interface incoming octet count), the Choose port dialog box opens, allowing you to select a port.
4. Leave the remaining fields at their default values, including a sample type of Delta, and click Insert. If the message "Alarm x already exists" appears, you must assign a new index. To view all the RMON alarms, choose RMON > Alarms.
