METHODS AND APPARATUS FOR SIMPLIFIED SETUP OF CENTRALIZED WLAN SWITCHING

Abstract

A wireless data communication system includes an access port configured to wirelessly communicate with a plurality of mobile units within multiple basic service sets (BSS), and a wireless switch having multiple predefined wireless local area networks (WLANs). The wireless switch is configured to automatically map the WLANs to the basic service sets and transmit to the access port a configuration template depending upon the type of access port. In one embodiment, there are n basic service sets, each having a corresponding basic service set identifier (BSSID), and m WLANs, each having a corresponding WLAN index, wherein the m WLAN indices are uniformly mapped to the n BSSIDs such that each BSSID has substantially the same number of WLAN indices mapped thereto. In a particular embodiment, there are n=4 BSSIDs per access port and m=16 pre-mapped WLANs. In this way, the wireless switch and respective access ports can be set-up in a simplified manner, in much the same way that set-up is performed with traditional access points.

9. The system of claim 8, wherein said template is transmitted to said access port during an adoption process performed by said wireless switch and said access port.

10. The system of claim 1, wherein said wireless switch includes additional predefined WLANs that are not pre-mapped to said basic service sets.

11. A method for setting up a wireless network comprising: providing an access port configured to wirelessly communicate with a plurality of mobile units within multiple basic service sets;providing a wireless switch having multiple predefined wireless local area networks (WLANs),automatically mapping said WLANs to said basic service sets;transmitting from said wireless switch to said access port a configuration template responsive to a type of said access port.

12. The method of claim 11, wherein transmitting said configuration template includes transmitting a set of default settings for said access port.

13. The method of claim 11, further including selectively enabling said WLANs.

14. The method of claim 12, wherein said template is transmitted to said access port during an adoption process performed by said wireless switch and said access port.
