You can specify the source IP address for outgoing HWTACACS packets in HWTACACS scheme view for
a specific HWTACACS scheme, or in system view for all HWTACACS schemes whose servers are in a
VPN or the public network.
Before sending an HWTACACS packet, the NAS selects a source IP address in the following order:
The source IP address specified for the HWTACACS scheme.
1.
The source IP address specified in system view for the VPN or public network, depending on where
2.
the HWTACACS server resides.
The IP address of the outbound interface specified by the route.
3.
To specify a source IP address for all HWTACACS schemes of a VPN or the public network:
Step
1. Enter system view.
2. Specify a source IP address
for outgoing HWTACACS
packets.
To specify a source IP address for a specific HWTACACS scheme:
Step
1. Enter system view.
2. Enter HWTACACS
scheme view.
3. Specify a source IP
address for outgoing
HWTACACS packets.
Setting HWTACACS timers
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. The timer starts immediately after an HWTACACS authentication,
authorization, or accounting request is sent. If the device receives no response from the server
before the 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 the server quiet 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 periodically send real-time accounting packets to the
accounting server for online users.
To set HWTACACS timers:
Step
1. Enter system view.
