802.1X port security configuration

802.1X accounting

When 802.1X port security is enabled on the Brocade device, you can enable 802.1X accounting. This feature enables the Brocade device to log information on the RADIUS server about authenticated 802.1X clients. The information logged on the RADIUS server includes the 802.1X client session ID, MAC address, and authenticating physical port number.

802.1X accounting works as follows.

1.A RADIUS server successfully authenticates an 802.1X client.

2.If 802.1X accounting is enabled, the Brocade device sends an 802.1X Accounting Start packet to the RADIUS server, indicating the start of a new session.

3.The RADIUS server acknowledges the Accounting Start packet.

4.The RADIUS server records information about the client.

5.When the session is concluded, the Brocade device sends an Accounting Stop packet to the RADIUS server, indicating the end of the session.

6.The RADIUS server acknowledges the Accounting Stop packet.

To enable 802.1X accounting, refer to “802.1X accounting configuration” on page 182.
