Chapter 5 Understanding SNMP

SNMP Traps

carOtherAuthServerNotResponding

carOtherAuthServerNotResponding indicates that an authentication server is not responding to a request sent from this server. This trap has three objects:

radiusAuthServerAddress—indicates the identity of the concerned server

radiusAuthClientServerPortNumber—indicates the port number of the concerned server

carAuthServerType—indicates the type of the concerned server

The index of these three objects identifies the entry in radiusAuthServerTable and carAccServerExtTable which maintains the characteristics of the concerned server.

Note One should not rely solely on carOtherAuthServerNotResponding for server state. Several conditions, including a restart of the Cisco AR server, could result in either multiple carOtherAuthServerNotResponding notifications being sent or in a carOtherAuthServerResponding notification not being sent. NMS can query the carAuthServerRunningState in carAuthServerExtTable for the current running state of this server.

carOtherAuthServerResponding

carOtherAuthServerResponding signifies that an authentication server which had formerly been in a down state is now responding to requests from the Cisco AR server. This trap has three objects:

radiusAuthServerAddress—indicates the identity of the concerned server

radiusAuthClientServerPortNumber—indicates the port number of the concerned server

carAuthServerType—indicates the type of the concerned server

The index of these three objects identifies the entry in radiusAuthServerTable and carAccServerExtTable which maintains the characteristics of the concerned server.

One should not rely on receiving this notification as an indication that all is well with the network. Several conditions, including a restart of the Cisco AR server, could result in either multiple carOtherAuthServerNotResponding notifications being sent or in a carOtherAuthServerResponding notification not being sent. The NMS can query the carAuthServerRunningState in carAuthServerExtTable for the current running state of this server.

carOtherAccServerNotResponding

carOtherAuthServerNotResponding signifies that an accounting server is not responding to the requests sent from this server. This trap has three objects:

radiusAccServerAddress—indicates the identity of the concerned server

radiusAccClientServerPortNumber—indicates the port number of the concerned server

carAcchServerType—indicates the type of the concerned server

The index of these three objects identifies the entry in radiusAuthServerTable and arAccServerExtTable which maintains the characteristics of the concerned server.

One should not solely rely on this for server state. Several conditions, including the restart of the Cisco AR server, could result in either multiple carOtherAccServerNotResponding notifications being sent or in a carOtherAccServerResponding notification not being sent. The NMS can query the carAccServerRunningState in carAccServerExtTable for current running state of this server.
