Specifying the HWTACACS authentication servers
You can specify one primary authentication server and a maximum of 16 secondary authentication
servers for an HWTACACS scheme. When the primary server is not available, the device searches
for the secondary servers in the order they are configured. The first secondary server in active state
is used for communication.
If redundancy is not required, specify only the primary server. An HWTACACS server can act 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 instance by using the
ip host
or
ipv6
host
command.
•
Configure a DNS server for the VPN instance by using the
dns server
or
ipv6 dns server
command.

By default, no authentication
server is specified.
Two HWTACACS authentication
servers in a scheme, primary or
secondary, cannot have the
same combination of hostname,
IP address, port number, and
VPN instance.
Specifying the HWTACACS authorization servers
You can specify one primary authorization server and a maximum of 16 secondary authorization
servers for an HWTACACS scheme. When the primary server is not available, the device searches
for the secondary servers in the order they are configured. The first secondary server in active state
is used for communication.
If redundancy is not required, specify only the primary server. An HWTACACS server can act as the
primary authorization server of one scheme and as the secondary authorization server of another
scheme at the same time.
