Release Information

Statement introduced in Junos OS Release 21.4R1.

Description

Enable the RADIUS reachability feature to authenticate sessions that are in server fail state once the authentication server becomes reachable. The authenticator checks for reachability by triggering reauthentication for one of the authentications sessions that previously failed to reach the server.

When an authentication session fails because the server is not reachable, the session is placed in held state or in the server-fail VLAN, if it is configured. If RADIUS reachability is not enabled, these sessions will not reauthenticate until the reauthentication timer expires. The reauthentication interval is typically long, one hour by default, forcing the client to wait even after the server is reachable.

Options

query-period seconds

Query period interval.

  • Default: 120 seconds.

  • Range: 20 through 65535 seconds.
