Table 208 Set IP Address and Port Number of RADIUS Server
Operation
Set IP address and port number of primary
RADIUS accounting server.
Restore IP address and port number of
primary RADIUS accounting server or server to
the default values.
Set IP address and port number of secondary
RADIUS authentication/authorization server.
Restore IP address and port number of
secondary RADIUS
authentication/authorization or server to the
default values.
Set IP address and port number of secondary
RADIUS accounting server.
Restore IP address and port number of
secondary RADIUS accounting server or server
to the default values.
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
