secondary authentication ip-address
[ port-number | vpn-instance
vpn-instance-name ] *
Configure at least one
command.
No authentication
server is specified by
default.
You can remove an authentication server only when no active TCP connection for sending authentication
packets is using it.
Specifying the HWTACACS authorization servers
You can specify one primary authorization server and one secondary authorization server for an
HWTACACS scheme. When the primary server is not available, the secondary server is used. If no
redundancy is needed, specify only the primary server.
An HWTACACS server can function as the primary authorization server of one scheme and as the
secondary authorization server of another scheme at the same time. You cannot specify the same IP
address as both the primary and the secondary authorization servers in a scheme.

Specifying the HWTACACS accounting servers and the relevant parameters
You can specify one primary accounting server and one secondary accounting server for an
HWTACACS scheme. When the primary server is not available, the secondary server is used. If no
redundancy is needed, specify only the primary server.
When the device receives a connection teardown request from a host or a connection teardown
command from an administrator, it sends a stop-accounting request to the accounting server. You can
enable buffering of non-responded stop-accounting requests to allow the device to buffer and resend a
