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. In a
scenario where redundancy is not required, 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.
You can remove an HWTACACS authorization server only when no active TCP connection for
sending authorization packets is using it.
To specify HWTACACS authorization servers for an HWTACACS scheme:
Step Command Remarks
1. Enter system view.

hwtacacs scheme
hwtacacs-scheme-name
N/A
3. Specify HWTACACS
authorization servers.
• Specify the primary HWTACACS
authorization server:
primary authorization
ip-address [ port-number | key
[ cipher | simple ] key |
vpn-instance
vpn-instance-name ] *
• Specify a secondary
HWTACACS authorization
server:
secondary authorization
ip-address [ port-number | key
[ cipher | simple ] key |
vpn-instance
vpn-instance-name ] *
Configure at least one
command.
No authorization server is
specified by default.
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. In a
scenario where redundancy is not required, 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.
You can remove an HWTACACS accounting server only when no active TCP connection for sending
accounting packets is using it.
HWTACACS does not support accounting for FTP users.
