stop-accounting request until it receives a response or the number of stop-accounting attempts reaches
the configured limit. In the latter case, the switch discards the packet.
Follow these guidelines when you configure HWTACACS accounting servers:
An HWTACACS server can function as the primary accounting server in one scheme and as a
•
secondary accounting server in another scheme.
The IP addresses of the primary and secondary accounting servers cannot be the same. Otherwise,
•
the configuration fails.
You can remove an accounting server only when no active TCP connection for sending accounting
•
packets is using it.
• HWTACACS does not support accounting for FTP users.
To specify HWTACACS accounting servers and set relevant parameters for an HWTACACS scheme:
Step
1. Enter system view.
2. Enter HWTACACS scheme
view.
3. Specify HWTACACS
accounting servers.
4. Enable buffering of
stop-accounting requests to
which no responses are
received.
5. Set the maximum number of
stop-accounting attempts.
Specifying the shared keys for HWTACACS communication
The HWTACACS client and HWTACACS server use the MD5 algorithm to encrypt packets exchanged
between them and use shared keys to authenticate the packets. They must use the same shared key for the
same type of packets.
To specify the shared keys for secure HWTACACS communication:
Step
1. Enter system view.
2. Enter HWTACACS scheme view.
Specify the shared keys for
3.
secure HWTACACS
authentication, authorization,
and accounting communication.
