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.
To specify HWTACACS authorization servers for an HWTACACS scheme:

Command Remarks
1. Enter system view.

3. Specify
HWTACACS
authorization
servers.
• Specify the primary HWTACACS authorization server:
primary authorization ip-address [ port-number |
vpn-instance vpn-instance-name ] *
• Specify a secondary HWTACACS authorization server:
secondary authorization ip-address [ port-number |
vpn-instance vpn-instance-name ] *
Configure at least one
command.
No authorization
server is specified by
default.
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 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
stop-accounting request until it receives a response or the number of stop-accounting attempts reaches
the configured limit. In the latter case, the device discards the packet.
An HWTACACS server can function as the primary accounting server of one scheme and as the
secondary accounting server of another scheme at the same time. You cannot specify the same IP
address as both the primary and the secondary accounting servers in a scheme.
HWTACACS does not support accounting for FTP users.
