Command Remarks
3. Specify
HWTACACS
authentication
servers.
• Specify the primary HWTACACS authentication server:
primary authentication ip-address [ port-number |
vpn-instance vpn-instance-name ] *
• Specify the secondary HWTACACS authentication
server:
secondary authentication ip-address [ port-number |
vpn-instance vpn-instance-name ] *
Configure at least
one command.
No authentication
server is specified
by default.
Specifying the HWTACACS authorization servers
You can specify one primary authorization server and up to one secondary authorization server for an
HWTACACS scheme so that the NAS can find a server for user authorization when using the scheme.
When the primary server is not available, the secondary server is used, if any. In a scenario where
redundancy is not required, specify only the primary server.
Follow these guidelines when you configure HWTACACS authorization servers:
• An HWTACACS server can function as the primary authorization server of one scheme and
simultaneously as the secondary authorization server of another scheme.
• The IP addresses of the primary and secondary authorization servers cannot be the same.
Otherwise, the configuration fails.
• You can remove an authorization server only when no active TCP connection for sending
authorization packets is using it.

Specifying the HWTACACS accounting servers and the relevant parameters
You can specify one primary accounting server and up to one secondary accounting server for an
HWTACACS scheme so that the NAS can find a server for user accounting when using the scheme.
When the primary server is not available, the secondary server is used, if any. In a scenario where
redundancy is not required, specify only the primary server.
When the firewall 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 firewall to buffer and resend a
stop-accounting request until it receives a response or the number of stop-accounting attempts reaches
the configured limit. In the latter case, the firewall discards the packet.
Follow these guidelines when you configure HWTACACS accounting servers:
