Description

 

Set the maximum number of attempts for transmitting a RADIUS packet to a

 

single RADIUS server. If the device does not receive a response to its request

 

from the RADIUS server within the response timeout period, it retransmits the

 

RADIUS request. If the number of transmission attempts exceeds the limit but

Request Transmission Attempts

the device still does not receive a response from the RADIUS server, the

device considers the request a failure.

 

 

 

IMPORTANT:

 

The server response timeout time multiplied by the maximum number of

 

RADIUS packet transmission attempts must not exceed 75.

 

Set the interval for sending real-time accounting information. The interval

 

must be a multiple of 3.

 

To implement real-time accounting, the device must send real-time

 

accounting packets to the accounting server for online users periodically.

Realtime Accounting Interval

Different real-time accounting intervals impose different performance

 

requirements on the NAS and the RADIUS server. A shorter interval helps

 

achieve higher accounting precision but requires higher performance. Use a

 

longer interval when a large number of users (1000 or more) exist. For more

 

information about the recommended real-time accounting intervals, see

 

"Configuration guidelines."

 

 

Realtime Accounting Attempts

Set the maximum number of attempts for sending a real-time accounting

request.

 

 

 

 

Specify the unit for data flows sent to the RADIUS server, which can be:

 

•

Byte.

Unit for Data Flows

•

Kilo-byte.

 

•

Mega-byte.

 

•

Giga-byte.

 

 

 

Specify the unit for data packets sent to the RADIUS server, which can be:

 

•

One-packet.

Unit for Packets

•

Kilo-packet.

 

•

Mega-packet.

 

•

Giga-packet.

 

 

Security Policy Server

Specify the IP address of the security policy server.

 

 

 

Specify the source IP address for the device to use in RADIUS packets sent to

 

the RADIUS server.

RADIUS Packet Source IP

HP recommends you to use a loopback interface address instead of a

 

physical interface address as the source IP address. If the physical interface

 

is down, the response packets from the server cannot reach the device.

 

 

 

Buffer stop-accounting packets

Enable or disable buffering of stop-accounting requests for which no

responses are received.
