ZyAIR
1As wireless station Y moves from the coverage area of access point P1 to that of access point
2P2, it scans and uses the signal of access point P2.
3Access point P2 acknowledges the presence of wireless station Y and relays this information to access point P1 through the wired LAN.
4Access point P1 updates the new position of wireless station.
5Wireless station Y sends a request to access point P2 for
The following requirements must be met in order for wireless stations to roam between the coverage areas.
1All the access points must be on the same subnet and configured with the same ESSID.
2If 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.
3The adjacent access points should use different radio channels when their coverage areas overlap.
4All access points must use the same port number to relay roaming information.
5The 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.
To enable roaming on your ZyAIR, click the WIRELESS link under ADVANCED and then the Roaming tab. The screen appears as shown.
