Default command level
2: System level
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, which must
be a valid global unicast address.
port-number: Specifies the service port number of the secondary RADIUS accounting server, which is a
UDP port number ranging from 1 to 65535 and defaults to 1813.
key [ cipher | simple ] key: Specifies the shared key for secure communication with the secondary
RADIUS accounting server. In FIPS mode, the shared key must be a string of at least 8 characters that
contain numbers, uppercase letters, lowercase letters, and special characters, and is encrypted and
decrypted by using 3DES.
cipher key: Specifies a ciphertext shared key, which is a case-sensitive ciphertext string of 1 to 1 17
•
characters.
simple key: Specifies a plaintext shared key, which is a case-sensitive string of 1 to 64 characters.
•
If neither cipher nor simple is specified, you set a plaintext shared key string.
•
vpn-instance vpn-instance-name: Specifies the MPLS L3VPN to which the secondary RADIUS accounting
server belongs. The vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. If the
server is on the public network, do not specify this option.
Usage guidelines
Make sure the port number and shared key settings of the secondary RADIUS accounting server are the
same as those configured on the server.
You can configure up to 16 secondary RADIUS accounting servers for a RADIUS scheme. After the
configuration, if the primary server fails, the device looks for a secondary server in active state (a
secondary RADIUS accounting server configured earlier has a higher priority) and tries to communicate
with it.
The IP addresses of the accounting servers and those of the authentication/authorization servers must be
of the same IP version.
The IP addresses of the primary and secondary accounting servers must be different from each other.
Otherwise, the configuration fails.
The shared key configured by this command takes precedence over that configured by using the key
accounting [ cipher | simple ] key command. For secrecy, all shared keys, including keys configured in
plain text, are saved in cipher text.
If the specified server resides on an MPLS VPN, specify the VPN by using the vpn-instance
vpn-instance-name option. The VPN specified by this command takes precedence over the VPN
specified for the RADIUS scheme.
If you remove a secondary accounting server when the device has already sent a start-accounting
request to the server, the communication with the secondary server times out, and the device looks for a
server in active state from the primary server on.
If you remove an accounting server being used by online users, the device can no longer send real-time
accounting requests or stop-accounting requests for the users, and it does not buffer the stop-accounting
requests.
