SNMP Traps

Supported Traps

The traps supported by Cisco Access Registrar enable Cisco AR to notify interested management stations of events, failure, or impending failure conditions. Traps are a network message of a specific format issued by an SNMP entity on behalf of a network management agent application. Traps are used to provide the management station with an asynchronous notification of an event.

carServerStart

carServerStart signifies that the server has started on the host from which this notification was sent. This trap has one object, carNotifStartType, which indicates the start type. A firstStart indicates this is the server process’ first start. reload indicates this server process has an internal reload. This typically occurs after rereading some configuration changes, but reload indicates this server process did not quit during the reload process.

carServerStop

carServerStop signifies that the server has stopped normally on the host from which this notification was sent.

carInputQueueFull

carInputQueueFull indicates that the percentage of use of the packet input queue has reached its high threshold. This trap has two objects:

carNotifInputQueueHighThreshold—indicates the high limit percentage of input queue usage

carNotifInputQueueLowThreshold—indicates the low limit percentage of input queue usage

By default, carNotifInputQueueHighThreshold is set to 90% and carNotifInputQueueLowThreshold is set to 60%.

Note The values for these objects cannot be changed at this time. You will be able to modify them in a future release of Cisco Access Registrar.

After this notification has been sent, another notification of this type will not be sent again until the percentage usage of the input queue goes below the low threshold.

If the percentage usage reaches 100%, successive requests may be dropped, and the server may stop responding to client requests until the queue drops down again.

carInputQueueNotVeryFull

carInputQueueNotVeryFull indicates that the percentage usage of the packet input queue has dropped below the low threshold defined in carNotifInputQueueLowThreshold. This trap has two objects:

carNotifInputQueueHighThreshold—indicates the high limit percentage of input queue usage

carNotifInputQueueLowThreshold—indicates the low limit percentage of input queue usage

After this type of notification has been sent, it will not be sent again until the percentage usage goes back up above the high threshold defined in carNotifInputQueueHighThreshold.
