5.8 802.1x authentication
Global configuration: enable 802.1x authentication function.
Radius client address: configure radius authentication client address.
Radius server shared secret key: a secret of up to 29 characters is shared between the
server and the switch.
Radius server timeout: (can be set to a number between 3 and 3600 seconds) It is the
maximum time to wait for a response from the server. If the server does not respond
within this time frame, we will consider it dead and continue to use the next enabled
server (if any); the RADIUS server uses the UDP protocol, which is not reliable by
design. In order to deal with the lost frames, the super interval is divided into three
sub intervals, each of which has the same length. If no response is received within the
subinterval, the request is transmitted again. This algorithm will cause radius server
to be queried up to three times before it is considered as dead server.
Radius server settings: set radius server attributes.
Radius server address: configure the radius server address.
Radius server port number: configure the radius server port number.
Radius server shared password: a secret of up to 29 characters is shared between the
server and the switch.
Radius server retransmission times: configure the radius service death retransmission
times.
