Functional Description
Forced Roaming on IP
cyclically. This is achieved using ICMP packets (Echo Request/Reply or Ping). If
the IP connection aborts; in
deauthentication frame is sent to all WLAN clients. The relevant WLAN interface is
then disabled.
The IP connection con
again as soon as the access point has received a ping reply from the pinged
station.
T he mechanism makes it possible, for example, to monitor a connection between
wireless clients and a server. If the server can no longer be reached over the
access point, the clients are deauthenticated and the WLAN interface of the access
p oint is disabled. The clients roam and then connect to a different access point
from which the server can be reached. As soon as the first access point can reach
the server again, it re-enables its WLAN interfaces.
