Configuration Guide Configuring RADIUS
The same shared key must be configured on the device and RADIUS security server so that they can
communicate with each other successfully.
 Configuring the Request Transmission Count, After Which the Device Confirms That a RADIUS Server Is
Unreachable
radius-server retransmitretries
retries: Indicates the RADIUS retransmission count. The value ranges from 1 to 100.
Global configuration mode
The prerequisite for AAA to use the next user authentication method is that the current security server used
for authentication does not respond. The criteria for the device to judge that a security server does not
respond are that the security server does not respond within the RADIUS packet retransmission duration of
the specified retransmission count. There is an interval between consecutive two retransmissions.
 Configuring the Waiting Time, After which the Device Retransmits a Request
radius-server timeoutseconds
seconds: Indicates the timeout time, with the unit of seconds. The value ranges from 1 second to 1,000
seconds.
Global configuration mode
Use this command to adjust the packet retransmission timeout time.
 Configuring Retransmission of Accounting Update Packets for Authenticated Users
radius-server account update retransmit
