HP 6125G Configuration Manual page 44

When the switch receives a connection teardown request from a host or a connection teardown
command from an administrator, it sends a stop-accounting request to the accounting server. You can
enable buffering of non-responded stop-accounting requests to allow the switch to buffer and resend a
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 specify HWTACACS accounting servers:
An HWTACACS server can function as the primary accounting server of one scheme and as the
•
secondary accounting server of another scheme at the same time.
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 secure HWTACACS communication
The HWTACACS client and HWTACACS server use the MD5 algorithm to authenticate packets
exchanged between them and use shared keys for packet authentication and user passwords encryption.
They must use the same key for the same type of communication.
To specify a shared key for secure HWTACACS communication:
Step
1. Enter system view.
2. Enter HWTACACS scheme
view.
