Figure 233   Roaming Example

The steps below describe the roaming process.

1 As wireless station Y moves from the coverage area of access point P1 to that of access 

point 

2 P2, it scans and uses the signal of access point P2. 

3 Access point P2 acknowledges the presence of wireless station Y and relays this 

information to access point P1 through the wired LAN. 

4 Access point P1 updates the new position of wireless station.

5 Wireless station Y sends a request to access point P2 for re-authentication.

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 ESSID. 

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.
