Creating/Deleting a RADIUS Server Group
As mentioned above, RADIUS protocol configurations are performed on the per
RADIUS server group basis. Therefore, before performing other RADIUS protocol
configurations, it is compulsory to create the RADIUS server group and enter its
view to set its IP address.
You can use the following commands to create/delete a RADIUS server group.
Perform the following configurations in system view.

Operation

Several ISP domains can use a RADIUS server group at the same time.
By default, the system has a RADIUS server group named "default" whose
attributes are all default values. The default attribute values will be introduced in
the following text.
Setting the IP Address and Port Number of RADIUS Server
After creating a RADIUS server group, you set IP addresses and UDP port numbers
for the RADIUS servers, including primary/second authentication/authorization
servers and accounting servers. So you can configure up to 4 groups of IP
addresses and UDP port numbers. However, you have to set one group of IP
address and UDP port number for each pair of primary/second servers to ensure
the normal AAA operation.
Perform the following configurations in RADIUS server group view.
