Note
To enable active detection of the specified RADIUS server,
the following conditions must be met:
1． Testing user name for this RADIUS server has been
configured on the device.
2． At least one tested port of this RADIUS server
(authentication port or accounting port) has been
configured on the device.
For a RADIUS server in reachable state, the device will
considered this RADIUS server unreachable if the following
two conditions are met:
1． The time configured by "radius-server dead-criteria
time seconds" is exceeded after correct response is last
received from this RADIUS server.
2． After correct response is last received from this RADIUS
server, the number of tries to send requests to this
RADIUS server when no correct response is received
has exceeded the number set by "radius-server
dead-criteria tries number".
For a RADIUS server in unreachable state, the device will
considered this RADIUS server reachable if any of the
following conditions is met:
1． Correct response is received from this RADIUS server.
2． The duration that this RADIUS server remains
unreachable exceeds the time set by "radius-server
deadtime", and active detection of this RADIUS server
is not enabled.
3． The authentication port or accounting port of this
RADIUS server is updated on the device.
RADIUS server reachability detection allows the user to configure the dead-criteria conditions
for a RADIUS server and active detection.
To configure RADIUS dead-server detection, execute the following commands in global
configuration mode:
Command Function
DES-7200# configure terminal
Enter the global configuration mode.
