Introduction
This document demonstrates how to configure access point (AP) Group VLANs with Wireless LAN
Controllers (WLCs) and Lightweight Access Points (LAPs).Prerequisites
Requirements
Ensure that you meet these requirements before you attempt this configuration:
• Basic knowledge of the configuration of LAPs and Cisco WLCs
• Basic knowledge ofLightweight Access Point Protocol (LWAPP)

Components Used
The information in this document is based on these software and hardware versions:
• Cisco 4400 WLC that runs firmware release 4.0
• Cisco1000 Series LAPs
• Cisco 802.11a/b/g Wireless Client Adapter that runs firmware release 2.6
• Cisco 2811 Router that runs Cisco IOS® Software Release 12.4(2)XA
• Two Cisco 3500 XL Series Switchesthat run Cisco IOS Software Release 12.0(5)WC3b
The information in this document was created from the devices in a specific lab environment. All of the
devices used in this document started with acleared (default) configuration. If your network is live, make sure
that you understand the potential impact of any command.

Background Information
In typical deployment scenarios, each WLAN is mapped to a single dynamic interface per WLC, but consider
a deployment scenario where there is a4404−100 WLC that supports the maximum number of APs (100).
Now consider a scenario where 25 users are associated to each AP. That would result in 2500 users who share
a single VLAN. Some customer...
