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, a UDP port

number in the range of 1 to 65535. The default setting is 1813.

key { cipher | simple } string: Sets the shared key for secure communication with the secondary RADIUS

accounting server.

• cipher string: Sets a ciphertext shared key. The string argument is case sensitive.

{ In non-FIPS mode, the key is a string of 1 to 117 cha ra ct e r s .

{ In FIPS mode, the key is a string of 15 to 117 c h aract e r s .

• simple string: Sets a plaintext shared key. The string argument is case sensitive.

{ In non-FIPS mode, the key is a string of 1 to 64 characters.

{ In FIPS mode, the key is a string of 15 to 64 characters that must contain digits, uppercase letters,

lowercase letters, and special characters.

vpn-instance vpn-instance-name: Specifies the MPLS L3VPN to which the secondary RADIUS accounting

server belongs, where vpn-instance-name 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 that the port number and shared key settings of each secondary RADIUS accounting server

are the same as those configured on the corresponding server.

You can configure up to 16 secondary RADIUS accounting servers for a RADIUS scheme. With 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.

Two accounting servers specified for a scheme, primary or secondary, cannot have identical IP address,

port number, and VPN settings.

The shared key configured by this command takes precedence over the shared key configured by using

the key accounting command.

If the specified server resides on an MPLS L3VPN, 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 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, and the device looks for an active server with the highest priority for accounting.

If you remove an actively used accounting server, the device no longer sends users' real-time accounting

requests and stop-accounting requests, and does not buffer the stop-accounting requests.

For security purposes, all shared keys, including shared keys configured in plain text, are saved in

ciphertext.
