The IP address of the outbound interface specified by the route
To specify a source IP address for all HWTACACS schemes:
To do… Use the command… Remarks
1. Enter system view.
system-view —
2. Specify a source IP
address for outgoing
HWTACACS packets.
hwtacacs nas-ip ip-address
Required.
By default, the IP address of the outbound
interface is used as the source IP address.
To specify a source IP address for a specific HWTACACS scheme:

Required.
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 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 the 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 the 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 periodically send real-time accounting packets to the
accounting server for online users.
The setting of the real-time accounting interval somewhat depends on the performance of the NAS and
the HWTACACS server. A shorter interval requires higher performance.
