Setting timers for controlling communication with HWTACACS servers
The switch uses the following timers to control the communication with an HWTACACS server:
Server
•
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
1. Enter system view.
2. Enter HWTACACS scheme
view.
3. Set the HWTACACS server
response timeout timer.
4. Set the quiet timer for the
primary server.
5. Set the real-time accounting
interval.
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.
