To do...
Create a RADIUS
scheme and enter its
view
Set the IP address and
port number of the
primary RADIUS
accounting server
Set the IP address and
port number of the
secondary RADIUS
accounting server
Enable stop-accounting
request buffering
Set the maximum
number of transmission
attempts of a buffered
stop-accounting request.
Set the maximum
allowed number of
continuous real-time
accounting failures
In an actual network environment, you can specify one server as both the primary and secondary
accounting servers, as well as specifying two RADIUS servers as the primary and secondary
accounting servers respectively. In addition, because RADIUS adopts different UDP ports to
exchange authentication/authorization messages and accounting messages, you must set a port
number for accounting different from that set for authentication/authorization.
With stop-accounting request buffering enabled, the switch first buffers the stop-accounting
request that gets no response from the RADIUS accounting server, and then retransmits the
request to the RADIUS accounting server until it gets a response, or the maximum number of
transmission attempts is reached (in this case, it discards the request).
You can set the maximum allowed number of continuous real-time accounting failures. If the
number of continuously failed real-time accounting requests to the RADIUS server reaches the set
maximum number, the switch cuts down the user connection.
The IP address and port number of the primary accounting server of the default RADIUS scheme
"system" are 127.0.0.1 and 1646 respectively.
Currently, RADIUS does not support the accounting of FTP users.
Use the command...
radius scheme
radius-scheme-name
primary accounting
ip-address [ port-number ]
secondary accounting
ip-address [ port-number ]
stop-accounting-buffer
enable
retry stop-accounting
retry-times
retry realtime-accounting
retry-times
2-13
Remarks
Required
By default, a RADIUS scheme named
"system" has already been created in
the system.
Required
By default, the IP address and UDP port
number of the primary accounting server
are 0.0.0.0 and 1813 for a newly created
RADIUS scheme.
Optional
By default, the IP address and UDP port
number of the secondary accounting
server are 0.0.0.0 and 1813 for a newly
created RADIUS scheme.
Optional
By default, stop-accounting request
buffering is enabled.
Optional
By default, the system tries at most 500
times to transmit a buffered
stop-accounting request.
Optional
By default, the maximum allowed
number of continuous real-time
accounting failures is five. If five
continuous failures occur, the switch
cuts down the user connection.
