4000 Router Series Security Command Reference

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

ciphertext.

Examples

# Specify a secondary authorization server with IP address 10.163.155.13, TCP port number 49, and

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