SNMP Traps and System Log Messages

The router can send Simple Network Management Protocol (SNMP) traps to alert network managers when:

• A RADIUS server fails to respond to a request.
• A RADIUS server that previously failed to respond to a request (and was consequently removed from the list of active servers) returns to active service.

  Returning to active service means that the E-series RADIUS client receives a valid response to an outstanding RADIUS request after the server is marked unavailable.

• All RADIUS servers within a VR context fail to respond to a request.

The router also generates system log messages when RADIUS servers fail to respond or when they return to active service; no configuration is required for system log messages.
