session length

Sessions continue when a client reauthenticates to the same WL520. Sessions are terminated when:

A client disassociates.

A client does not transmit any data to the WL520 for a fixed amount of time.

A client is detected on a different interface.

If the client roams from one WL520 to another, one session is terminated and a new session is begun.

NOTE:

This feature requires RADIUS authentication using MAC Access Control or 802.1x. Wireless clients configured in the

WL520’s static MAC Access Control list are not tracked.
