HP MSR Series Command Reference Manual page 101

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. The
value range for the TCP port number is 1 to 65535, and 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 key is a string of 1 to 373 characters.
In FIPS mode, the 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 key is a string of 1 to 255 characters.
In FIPS mode, the key is a string of 15 to 255 characters. The string must contain digits,
uppercase letters, lowercase letters, and special characters.
single-connection: The device and the primary HWTACACS authentication server use the same TCP
connection to exchange all authentication packets for all users. If you do not specify this keyword, the
device establishes a new TCP connection each time it exchanges authentication packets with the primary
authentication server for a user. If the HWTACACS server supports the single-connection method, HP
recommends that you specify this keyword to reduce TCP connections for improving system performance.
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.
