HP 5920 Command Reference Manual page 88

• 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 numbers, uppercase letters, lowercase letters, and special characters.
vpn-instance vpn-instance-name: Specifies the MPLS L3VPN to which the secondary HWTACACS
authorization 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 secondary HWTACACS authorization
server are the same as those configured on the server.
You can configure up to 16 secondary HWTACACS authorization servers for an HWTACACS scheme.
With the configuration, if the primary server fails, the device looks for a secondary server in active state
(a secondary HWTACACS authorization server configured earlier has a higher priority) and tries to
communicate with it.
If you use the undo secondary authorization command without specifying any parameter, the command
removes all secondary authorization servers.
Two authorization 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 authorization server only when it is not used for user authorization. Removing an
authorization server affects only authorization processes that occur after the remove operation.
For security purpose, all shared keys, including shared keys configured in plain text, are saved in cipher
text.
Examples
# Specify a secondary authorization server with IP address 10.163.155.13, TCP port number 49, and
plaintext shared key abc for HWTACACS scheme hwt1.
<Sysname> system-view
