Parameters

ipv4-address: Specifies the IPv4 address of the primary HWTACACS authentication server.

ipv6 ipv6-address: Specifies the IPv6 address of the primary HWTACACS authentication server.

port-number: Specifies the service port number of the primary HWTACACS authentication server, a TCP

port number in the range of 1 to 65535. The default setting is 49.

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

HWTACACS authentication server.

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

{ In non-FIPS mode, the shared key is a string of 1 to 373 characters.

{ In FIPS mode, the shared key is a string of 15 to 373 characters.

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

{ In non-FIPS mode, the shared key is a string of 1 to 255 characters.

{ In FIPS mode, the shared key is a string of 15 to 255 characters that must contain digits,

uppercase letters, lowercase letters, and special characters.

vpn-instance vpn-instance-name: Specifies the MPLS L3VPN to which the primary HWTACACS

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 port number and shared key settings of the primary HWTACACS 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.

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 HWTACACS scheme.

You can remove an authentication server only when it is not used for user authentication. Removing an

authentication server affects only authentication processes that occur after the remove operation.

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

ciphertext.

Examples

# Specify the primary authentication server with IP address 10.163.155.13, TCP port number 49, and

plaintext shared key 123456TESTauth&! for HWTACACS scheme hwt1.
