.1.3.6.1.2.1.131.0.1 |
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. |

An entStateOperDisabled 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 'disabled' 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 affect the physical entity's ability to stay operationally enabled. |
