Parameters
ipv4-address: Specifies the IPv4 address of the primary RADIUS authentication server.
ipv6 ipv6-address: Specifies the IPv6 address of the primary RADIUS authentication server.
port-number: Specifies the service port number of the primary RADIUS authentication server, a UDP port
number in the range of 1 to 65535. The default setting is 1812.
key { cipher | simple } string: Sets the shared key for secure communication with the primary RADIUS
authentication 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 characters. In FIPS mode, the key is a string of 15 to 117 characters.
• 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 and
must contain numbers, uppercase letters, lowercase letters, and special characters.
vpn-instance vpn-instance-name: Specifies the MPLS L3VPN to which the primary RADIUS authentication
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 service port and shared key settings of the primary RADIUS authentication server are
the same as those configured on the server.
Two authentication 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 that configured by using the key
authentication 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.
