RADIUS Accounting and 802.1x Dynamic
VLAN Assignment
The RADIUS server can now be configured to allow a user to be authenticated
in only one place at a time. This is achieved by limiting the number of open
RADIUS accounting sessions for a supplicant to one, and provides for greater
security.
Radius accounting is included for:
■ MAC based port authentication
■ 802.1x port authentication in single-supplicant mode.
When a supplicant has been authenticated for a port, a START
Accounting-Request message is sent to the RADIUS server.
When a supplicant becomes unauthenticated, a STOP Accounting-Request
message is sent to the RADIUS server.
If no Accounting-Response is received from the RADIUS server after either a
START or STOP Accounting message is sent, (and once the RADIUS module
has reached its timeout and retry limit), the authorisation status of the
supplicant remains unaffected, but an appropriate message is logged.
