SNMP is configured on your routing devices. 

Familiarity with the ENTITY-MIB and the CISCO-ENTITY-ALARM-MIB.

The CISCO-ENTITY-ALARM-MIB supports reporting of alarms for physical entities only. For line 
cards, alarms are reported at the physical interface or port level.

To configure alarm filtering in the Cisco Entity Alarm MIB, you should understand the following 
concepts:

The CISCO-ENTITY-ALARM-MIB provides a management client with the capability to monitor alarms 
generated by physical entities in a network that are identified in the entPhysicalTable of the Entity-MIB 
(RFC 2737). Examples of these physical entities are chassis, fans, modules, ports, slots, and power 
supplies. The management client interfaces with an SNMP agent to request access to objects defined in 
the CISCO-ENTITY-ALARM-MIB.

The ceAlarmGroup is a group in the CISCO-ENTITY-ALARM-MIB that defines objects that provide 
current statuses of alarms and the capability to instruct an agent to stop (cut off) signaling for any or all 
external audible alarms.

Following are the objects in ceAlarmGroup:

ceAlarmCriticalCount

ceAlarmMajorCount

ceAlarmMinorCount

ceAlarmCutoff
