Rmon Events; Configuration Guidelines And Limitations For Rmon - Cisco Nexus 5600 Series Configuration Manual

RMON Events

• Sample type—Absolute samples take the current snapshot of the MIB object value. Delta samples take
• Rising threshold—The value at which the Cisco Nexus device triggers a rising alarm or resets a falling
• Falling threshold—The value at which theCisco Nexus device triggers a falling alarm or resets a rising
• Events—The action that the Cisco Nexus device takes when an alarm (rising or falling) triggers.
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 does 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.
