Usage guidelines
Make sure the port number and shared key settings of each secondary RADIUS authentication
server are the same as those configured on the corresponding server.
A RADIUS scheme supports a maximum of 16 secondary RADIUS authentication servers. If the
primary server fails, the device tries to communicate with a secondary server in active state. The
device connects to the secondary servers in the order they are configured.
The server status detection is triggered for a server if the specified test profile exists on the device.
Two authentication servers specified for a scheme, primary or secondary, cannot have identical VPN
instance, host name, IP address, and port number settings.
The shared key configured by this command takes precedence over the shared key configured with
the
key authentication
command.
If the specified server resides on an MPLS L3VPN, specify the VPN instance by using the
vpn-instance vpn-instance-name
option. The VPN instance specified by this command
takes precedence over the VPN instance specified for the RADIUS scheme.
If you use the
secondary authentication
command to modify or delete a secondary
authentication server during an authentication process, communication with the secondary server
times out.
•
When the RADIUS server load sharing feature is disabled, the device tries to communicate with
an active server that has the highest priority for authentication.
•
When the RADIUS server load sharing feature is enabled, the device performs the following
operations:
a. Checks the weight value and number of currently served users for each active server.
b. Determines the most appropriate server in performance to receive an AAA request.
Examples
# In RADIUS scheme radius1 , specify a secondary authentication server with IP address 10.110.1.2
and UDP port 1812.
<Sysname> system-view
[Sysname] radius scheme radius1
[Sysname-radius-radius1] secondary authentication 10.110.1.2 1812
# In RADIUS scheme radius2 , specify two secondary authentication servers with IP addresses
10.110.1.1 and 10.110.1.2 and UDP port 1812.
<Sysname> system-view
[Sysname] radius scheme radius2
[Sysname-radius-radius2] secondary authentication 10.110.1.1 1812
[Sysname-radius-radius2] secondary authentication 10.110.1.2 1812
