Parameters
ipv4-address: Specifies the IPv4 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 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 and 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.
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 and port number settings.
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.
