Specifying the HWTACACS accounting servers
You can specify one primary accounting server and a maximum of 16 secondary accounting servers
for an HWTACACS scheme. When the primary server is not available, the device searches for the
secondary servers in the order they are configured. The first secondary server in active state is used
for communication.
If redundancy is not required, specify only the primary server. 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 device sends HWTACACS stop-accounting requests when it receives connection teardown
requests from hosts or connection teardown commands from an administrator. However, the device
might fail to receive a response for a stop-accounting request in a single transmission. Enable the
device to buffer HWTACACS stop-accounting requests that have not received responses from the
accounting server. The device will resend the requests until responses are received.
To limit the transmission times, set a maximum number of attempts that can be made for transmitting
individual HWTACACS stop-accounting requests. When the maximum attempts are made for a
request, the device discards the buffered request.
HWTACACS does not support accounting for FTP, SFTP, and SCP users.
