By default, as for the "system" RADIUS scheme created by the system:

The IP address of the primary authentication server is 127.0.0.1, and the UDP port 
number is 1645.

The IP address of the secondary authentication server is 0.0.0.0, and the UDP port 
number is 1812.

The IP address of the primary accounting server is 127.0.0.1, and the UDP port 
number is 1646

The IP address of the secondary accounting server is 0.0.0.0, and the UDP port 
number is 1813;

As for the newly created RADIUS scheme:

The IP address of the primary/secondary authentication server is 0.0.0.0, and the 
UDP port number of this server is 1812;

The IP address of the primary/secondary accounting server is 0.0.0.0, and the UDP 
port number of this server is 1813;

In real networking environments, the above parameters shall be set according to 
the specific requirements. For example, you may specify 4 groups of different data 
to map 4 RADIUS servers, or specify one of the two servers as primary 
authentication/authorization server and secondary accounting server and the 
other one as secondary authentication/authorization server and primary 
accounting server, or you may also set 4 groups of exactly same data so that every 
server serves as a primary and secondary AAA server.

To guarantee the normal interaction between NAS and RADIUS server, you are 
supposed to guarantee the normal routes between RADIUS/HWTACACS server 
and NAS before setting IP address and UDP port of the RADIUS server and IP 
address and TCP port of the HWTACACS server. In addition, because 
RADIUS/HWTACACS protocol uses different ports to receive/transmit 

Set IP address and port number of primary 
RADIUS accounting server.
