Parameters
ipv4-address: Specifies the IPv4 address of the secondary RADIUS accounting server.
ipv6 ipv6-address: Specifies the IPv6 address of the secondary RADIUS accounting server.
port-number: Specifies the service port number of the secondary RADIUS accounting server. The
value range for the UDP port number is 1 to 65535. The default setting is 1813.
key: Specifies the shared key for secure communication with the secondary RADIUS accounting
server.
cipher: Specifies the key in encrypted form.
simple: Specifies the key in plaintext form. For security purposes, the key specified in plaintext form
will be stored in encrypted form.
string: Specifies the key. This argument is case sensitive.
•
In non-FIPS mode, the encrypted form of the key is a string of 1 to 117 characters. The plaintext
form of the key is a string of 1 to 64 characters.
•
In FIPS mode, the encrypted form of the key is a string of 15 to 117 characters. The plaintext
form of the key is a string of 15 to 64 characters. The plaintext string must contain digits,
uppercase letters, lowercase letters, and special characters.
weight weight-value: Specifies a weight value for the RADIUS server. The value range for the
weight-value argument is 0 to 100, and the default value is 0. The value 0 indicates that the RADIUS
server will not be used for load sharing. This option takes effect only when the RADIUS server load
sharing feature is enabled for the RADIUS scheme. A larger weight value represents a higher
capacity to process accounting requests.
Usage guidelines
Make sure the port number and shared key settings of each secondary RADIUS accounting server
are the same as those configured on the corresponding server.
A RADIUS scheme supports a maximum of 16 secondary RADIUS accounting 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.
Two accounting servers specified for a scheme, primary or secondary, cannot have identical IP
address and port number settings.
The shared key configured by this command takes precedence over the shared key configured with
the key accounting command.
If you use the secondary accounting command to modify or delete a secondary accounting server
to which the device is sending a start-accounting request, 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 accounting.
•
When the RADIUS server load sharing feature is enabled, the device returns an accounting
failure message rather than searching for another active accounting server.
If you remove an actively used accounting server, the device no longer sends users' real-time
accounting requests and stop-accounting requests. The device does not buffer the stop-accounting
requests, either.
