Guidelines for Converting Autonomous Access Points to Lightweight Mode
Access points that are converted to lightweight mode do not support Wireless Domain Services (WDS). Converted access points communicate only with Cisco wireless LAN devices and cannot communicate with WDS devices. However, the device provides functionality that is equivalent to WDS when an access point is associated to it.
All Cisco lightweight access points support 16 Basic Service Set Identifiers (BSSIDs) per radio and a total of 16 wireless LANs per access point. When a converted access point is associated to a device, only wireless LANs with IDs 1 through 16 are pushed to the access point, unless the access point is a member of an access point group.
Access points that are converted to lightweight mode must get an IP address and discover the device using DHCP, DNS, or IP subnet broadcast.
