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 device 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 device starts this timer. If the device 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 device changes the server's status to blocked, starts this timer for the
server, and tries to communicate with another server in active state. After this timer expires, the
device changes the status of the server back to active.
•
Real-time accounting timer (realtime-accounting)—Defines the interval at which the device sends
real-time accounting updates to the HWTACACS accounting server for online users. To implement
real-time accounting, the device 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.

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.
5 seconds by default.
4.
Set the quiet timer for the
primary server.
timer quiet minutes
Optional.
5 minutes by default.
5.
Set the real-time accounting
interval.
timer realtime-accounting minutes
Optional.
12 minutes by default.
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.
