R0106-HP MSR Router Series Security Command Reference(V7)

92
You can configure up to 16 secondary HWTACACS authentication servers for an HWTACACS scheme.
If the primary server fails, the device tries to communicate with a secondary server in active state. The
device connects to the secondary servers in the order they are configured.
If you do not specify any parameters for the undo secondary authentication command, the command
removes all secondary authentication servers.
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.
