To create an HWTACACS scheme:
Step
1. Enter system view.
2. Create an HWTACACS
scheme and enter its view.
Specifying the HWTACACS authentication servers
You can specify one primary authentication server and up to 16 secondary authentication servers for an
HWTACACS scheme. When the primary server is not available, the device tries to communicate with the
secondary servers in the order they are configured, and communicates with the first secondary server in
active state. If redundancy is not required, specify only the primary server. An HWTACACS server can
function as the primary authentication server in one scheme and as the secondary authentication server
in another scheme at the same time.
To specify an HWTACACS server by hostname in an MPLS VPN network, first complete one of the
following tasks on the device:
Configure hostname-to-IP address mappings for the VPN by using the ip host or ipv6 host
•
command.
• Configure a DNS server for the VPN by using the dns server or ipv6 dns server command.
For more information about these commands, see Layer 3—IP Services Command Reference.
To specify HWTACACS authentication servers for an HWTACACS scheme:
Step
1. Enter system view.
2. Enter HWTACACS
scheme view.
3. Specify HWTACACS
authentication servers.
Specifying the HWTACACS authorization servers
You can specify one primary authorization server and up to 16 secondary authorization servers for an
HWTACACS scheme. When the primary server is not available, the device tries to communicate with the
secondary servers in the order they are configured, and communicates with the first secondary server in
active state. If redundancy is not required, specify only the primary server. An HWTACACS server can

By default, no authentication
server is specified.
The host-name argument is
available in Release 2310 and
later versions.
Two HWTACACS authentication
servers in a scheme, primary or
secondary, cannot have the same
combination of hostname, IP
address, port number, and VPN.
