37.2.19 Configuring the Backup
Authentication Server.
Our 802.1X-based authentication system can support the backup server. When the master
server is down due to various reasons, the device automatically issues a server submission
authentication request to the method list server group.
In the privileged mode, you can set the backup authentication server through the following
steps:
Command
Function
configure terminal
Enter the global configuration mode.
aaa new-model
Turn on the AAA switch.
aaa group server radius gs-name
Configure the server group.
server sever
Configure the server.
server server-backup
Configure the backup server.
end
Return to the privileged mode.
write
Save the configuration.
show dot1x
Show the configuration.
The following example configures 192.168.4.12 to be the backup server:
DGS-3610# configure terminal
DGS-3610# aaa new-model
DGS-3610(config)# aaa group server radius auth-ll
DGS-3610(config-gs-radius)# server 192.168.4.1
DGS-3610(config-gs-radius)# server 192.168.4.12
DGS-3610(config-gs-radius)# end
