Description
Use the state command to set the status of a RADIUS server.
By default, all the RADIUS servers in a user-defined RADIUS scheme are in the block
state.
For the primary and secondary servers (authentication/authorization servers, or
accounting servers) in a RADIUS scheme, note that:
z When the NAS fails to communicate with the primary server due to some server
trouble, the NAS will actively exchange packets with the secondary server.
z After the primary server recovers, the NAS does not immediately restore the
communication with the primary server, but keeps communicating with the
secondary server unit the secondary server also fails. In order for the NAS to
quickly restore the communication with the recovered primary server, you need to
manually set the state of the primary server to active by using the state command.
z When both the primary and secondary servers are in the active state, the NAS
sends packets to the primary server only.
