entStateOperEnabled
Module: ENTITY-STATE-MIB
OID (symbolic): ENTITY-STATE-MIB::entStateOperEnabled
OID (numeric): 1.3.6.1.2.1.131.0.1
Node type: NOTIFICATION-TYPE
Description: An entStateOperEnabled notification signifies that the SNMP entity, acting in an agent role, has detected that the entStateOper object for one of its entities has transitioned into the 'enabled' state.
The entity this notification refers can be identified by extracting the entPhysicalIndex from one of the variable bindings. The entStateAdmin and entStateAlarm varbinds may be examined to find out additional information on the administrative state at the time of the operation state change as well as to find out whether there were any known alarms against the entity at that time that may explain why the physical entity has become operationally disabled.
Examples
Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):
snmptrap -v2c -c public <manager> '' ENTITY-STATE-MIB::entStateOperEnabled snmptrap -v2c -c public <manager> '' 1.3.6.1.2.1.131.0.1
Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):
snmptrapd -f -Lo -c /dev/null authCommunity log public
Example snmptrapd log entry:
zoo11-linux.zoo [UDP: [192.168.30.111]:60513->[192.168.30.10]:162]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (440479841) 50 days, 23:33:18.41 SNMPv2-MIB::snmpTrapOID.0 = OID: ENTITY-STATE-MIB::entStateOperEnabled

Create custom SNMP monitor using the ENTITY-STATE-MIB::entStateOperEnabled OID value, configure state conditions and alerts, and monitor any Chassis-based router/switch with modular/redundant hardware (entity state extension, vendor-neutral IETF standard RFC 4268) from a single console.
