Step Command

Remarks

2.

Enter HWTACACS scheme
view.

hwtacacs scheme
hwtacacs-scheme-name

N/A

3.

Specify a source IP address
for outgoing HWTACACS

packets.

nas-ip ip-address

By default, the IP address of the
outbound interface is used as the
source IP address.

Setting timers for controlling communication with HWTACACS servers

The firewall uses the following timers to control the communication with an HWTACACS server:

Server response timeout timer (response-timeout)—Defines the HWTACACS request
retransmission interval. After sending an HWTACACS request (authentication, authorization, or

accounting request), the firewall starts this timer. If the firewall receives no response from the server

before this timer expires, it resends the request.

Server quiet timer (quiet)—Defines the duration to keep an unreachable server in blocked state. If
a server is not reachable, the firewall changes the server status to blocked, starts this timer for the

server, and tries to communicate with another server in active state. After this timer expires, the

firewall changes the status of the server back to active.

Real-time accounting timer (realtime-accounting)—Defines the interval at which the firewall sends
real-time accounting updates to the HWTACACS accounting server for online users. To implement

real-time accounting, the firewall must send real-time accounting packets to the accounting server
for online users periodically.

To set timers for controlling communication with HWTACACS servers:

Step Command

Remarks

1.

Enter system view.

system-view

N/A

2.

Enter HWTACACS scheme

view.

hwtacacs scheme
hwtacacs-scheme-name

N/A

3.

Set the HWTACACS server
response timeout timer.

timer response-timeout seconds

Optional.
The default HWTACACS server
response timeout timer is 5 seconds.

4.

Set the quiet timer for the
primary server.

timer quiet minutes

Optional.
The default quiet timer for the primary
server is 5 minutes.

5.

Set the real-time accounting
interval.

timer realtime-accounting minutes

Optional.
The default real-time accounting
interval is 12 minutes.

NOTE:

Consider the performance of the NAS and the HWTACACS server when you set the real-time accounting
interval. A shorter interval requires higher performance.
