Stop-Accounting Buffer
Enable or disable buffering stop-accounting requests without responses in the
device.
Since stop-accounting requests affect the charge to users, a NAS must make its
best effort to send every stop-accounting request to the HWTACACS accounting
servers. For each stop-accounting request getting no response in the specified
period of time, the NAS buffers and resends the packet until it receives a
response or the number of transmission retries reaches the configured limit. In
the latter case, the NAS discards the packet.
Stop-Accounting Packet
Retransmission Times
The maximum number of stop-accounting packet transmission attempts if no
response is received for the stop-accounting packet.
If stop-accounting buffer is disabled, this value is ineffective.
If you leave this field blank, the number of retransmission times is restored to the
default value.
Response Timeout Interval
Set the HWTACACS server response timeout time.
If no response is received from the server within the timeout interval, it may lead
to disconnection from the HWTACACS server.
If you leave this field blank, the response timeout period is restored to the default
value.
IMPORTANT:
As HWTACACS is based on TCP, the timeout of the server response timeout timer
and/or the TCP timeout timer will cause the NAS to be disconnected from the
HWTACACS server.
Quiet Interval
Specify the interval the primary server has to wait before being active.
If you leave this field blank, the quiet interval is restored to the default value.
Username Format
Set the format of the username sent to the HWTACACS server.
A username is generally in the format of userid@isp-name, of which isp-name is
used by the device to determine the ISP domain to which the user belongs. If an
HWTACACS server does not accept a username including an ISP domain
name, you can configure the device to remove the domain name before sending
it to the HWTACACS server.
Options include:
• without-domain—Specifies to remove the domain name of a username that is
to be sent to the RADIUS server.
• with-domain—Specifies to keep the domain name of a username that is to be
sent to the RADIUS server.
Unit of Data Flows
Specify the unit for data flows sent to the HWTACACS server for traffic
accounting. Options include:
• byte.
• kilo-byte.
• mega-byte.
• giga-byte.
If you leave the box blank, the default unit is used.
