Authentication, Authorization and Accounting (AAA) Commands
OL-32830-01 Command Line Interface Reference Guide
User Guidelines
This command enables the recording of 802.1x sessions.
If accounting is activated, the device sends start/stop messages to a RADIUS
server when a user logs in / logs out to the network, respectively.
The device uses the configured priorities of the available RADIUS servers in order
to select the RADIUS server.
If a new supplicant replaces an old supplicant (even if the port state remains
authorized), the software sends a stop message for the old supplicant and a start
message for the new supplicant.
In multiple sessions mode (dot1x multiple-hosts authentication), the software
sends start/stop messages for each authenticated supplicant.
In multiple hosts mode (dot1x multiple-hosts), the software sends start/stop
messages only for the supplicant that has been authenticated.
The software does not send start/stop messages if the port is force-authorized.
The software does not send start/stop messages for hosts that are sending traffic
on the guest VLAN or on the unauthenticated VLANs.
The following table describes the supported Radius accounting Attributes Values
