Parameters
ip-address: Specifies the IP address of the secondary HWTACACS authentication server in dotted
decimal notation. The default is 0.0.0.0.
port-number: Specifies the service port number of the secondary HWTACACS authentication server. The
value range for the port number is 1 to 65535, and the default is 49.
key [ cipher | simple ] key: Specifies the shared key for secure communication with the secondary
HWTACACS authentication server.
• cipher key: Specifies a ciphertext shared key, which is a case-sensitive ciphertext string of 1 to 373
characters.
• simple key: Specifies a plaintext shared key, which is a case-sensitive string of 1 to 255 characters.
• If neither cipher nor simple is specified, you set a plaintext shared key string.
• In FIPS mode, the shared key must contain at least eight characters and the plaintext shared key
string must contain digits, uppercase letters, lowercase letters, and special characters.
vpn-instance vpn-instance-name: Specifies the MPLS L3VPN to which the secondary HWTACACS
authentication 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 HWTACACS authentication server
are the same as those configured on the server.
The IP addresses of the primary and secondary authentication servers must be different. Otherwise, the
configuration fails.
If the specified server resides on an MPLS VPN, specify the VPN by using the vpn-instance
vpn-instance-name option.
The shared key configured by this command takes precedence over that configured by using the key
authentication [ cipher | simple ] key command.
If you execute the command multiple times, the most recent configuration takes effect.
You can remove an authentication server only when it is not used by any active TCP connection to send
authentication packets is using it. Removing an authentication server only affects authentication
processes that occur after the remove operation.
The VPN specified by this command takes precedence over the VPN specified for the HWTACACS
scheme.
