Command Mode
Global Configuration.
User Guidelines
This command enables the recording of 802.1x sessions.
If accounting is activated, the device sends a Start/Stop message to a RADIUS server when a user
logs in/logs out to the network, respectively. The software sends Start/Stop messages for each authenticated
supplicant.
The device uses the configured priorities of the available RADIUS servers to select the RADIUS server to
use.
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.
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 Attribute Values when they are sent by the
switch:
