RMON Events

• Rising threshold—The value at which the Cisco Nexus 5000 Series switch triggers a rising alarm or
• Falling threshold—The value at which the Cisco Nexus 5000 Series switch triggers a falling alarm or
• Events—The action that the Cisco Nexus 5000 Series switch takes when an alarm (rising or falling)
Use the hcalarms option to set an alarm on a 64-bit integer MIB object.
Note
For example, you can set a delta type rising alarm on an error counter MIB object. If the error counter delta
exceeds this value, you can trigger an event that sends an SNMP notification and logs the rising alarm event.
This rising alarm will not occur again until the delta sample for the error counter drops below the falling
threshold.
The falling threshold must be less than the rising threshold.
Note
RMON Events
You can associate a particular event to each RMON alarm. RMON supports the following event types:
• SNMP notification—Sends an SNMP risingAlarm or fallingAlarm notification when the associated
• Log—Adds an entry in the RMON log table when the associated alarm triggers.
• Both—Sends an SNMP notification and adds an entry in the RMON log table when the associated alarm
You can specify a different even for a falling alarm and a rising alarm.

Configuration Guidelines and Limitations

RMON has the following configuration guidelines and limitations:
• You must configure an SNMP user an notification receiver to use the SNMP notification event type.
• You can only configure an RMON alarm on a MIB object that resolves to an integer.

Configuring RMON Alarms

You can configure RMON alarms on any integer-based SNMP MIB object.
You can optionally specify the following parameters:
• The event-number to trigger if the rising or falling threshold exceeds the specified limit.
