Table 86 Configuration items
Item Descri
tion
NAS-IP
Source IP address for the device to use in HWTACACS packets to be sent to the
HWTACACS server. Use a loopback interface address instead of a physical
interface address as the source IP address to make sure that the response
packets from the server can reach the device when the physical interface is
down.
Realtime-Accounting
Interval
Real-time accounting interval, whose value must be a multiple of 3.
To implement real-time accounting on users, it is necessary to set the real-time
accounting interval. After this parameter is specified, the device will send the
accounting information of online users to the HWTACACS server every the
specified interval. According to the protocol, the device will not disconnect the
online users even if the server does not make any response properly.
If you leave this field blank, the real-time accounting interval is restored to the
default value.
IMPORTANT:
The value of the real-time accounting interval somewhat depends on the
performance of the NAS and HWTACACS server. A short interval requires higher
performance. Use a longer interval when there are a large number of users
(≥1000).
For
the recommended ratios of the interval to the number of users, see
"Configuration guidelines."
