Figure 27 Roaming Example
The steps below describe the roaming process.
1 As wireless station Y moves from the coverage area of access point AP 1 to that of access
point
2 AP 2 , it scans and uses the signal of access point AP 2 .
3 Access point AP 2 acknowledges the presence of wireless station Y and relays this
information to access point AP 1 through the wired LAN.
4 Access point AP 1 updates the new position of wireless station.
5 Wireless station Y sends a request to access point AP 2 for reauthentication.
5.7.1 Requirements for Roaming
The following requirements must be met in order for wireless stations to roam between the
coverage areas.
1 All the access points must be on the same subnet and configured with the same SSID.
2 If IEEE 802.1x user authentication is enabled and to be done locally on the access point,
the new access point must have the user profile for the wireless station.
3 The adjacent access points should use different radio channels when their coverage areas
overlap.
4 All access points must use the same port number to relay roaming information.
5 The access points must be connected to the Ethernet and be able to get IP addresses from
a DHCP server if using dynamic IP address assignment.
