Setting timers for controlling communication with HWTACACS servers
The switch 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 switch starts this timer. If the switch 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 switch 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
switch changes the status of the server back to active.
• Real-time accounting timer (realtime-accounting)—Defines the interval at which the switch sends
real-time accounting updates to the HWTACACS accounting server for online users. To implement
real-time accounting, the switch 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 accountin
g
interval. A shorter interval requires higher performance. A shorter interval requires hi
g
her performance.
