WLSE is a central placed management station for Finding errors, trouble shoot, optimizing RF performance, IOS updates, deployment of global config changes that are shared with all APs and rough AP detection if WDS is used.
Q. What is the role of the Wireless LAN Solution Engine (WLSE) in a WDS-enabled wireless LAN (WLAN) network?
A. APs and, optionally, Cisco client devices or Cisco-compatible client devices take radio frequency (RF) measurements within a single subnetwork. Cisco SWAN WDS aggregates the measurements and forwards the measurements to CiscoWorks WLSE for analysis. With these measurements as a basis, CiscoWorks WLSE can:
* Detect rogue APs and interference from other devices
* Provide assisted site surveys
* Support WLAN self-healing for optimal channel and power-level setting
Q. What are the advantages of the use of WDS on a Wireless LAN Services Module (WLSM)?
A. The introduction of switch-based WDS and the WLSM facilitates Layer 3 (L3) fast secure roaming (FSR) and provides a highly scalable solution for L3 mobility in the campus. Switch-based WDS centralizes the functionality of WDS in the WLSM blade in a central switch and provides these benefits:
* Increased WDS scalability?The scalability increases to 300 APs and 6000 users across a campus wireless LAN (WLAN) network.
* Simplified design and implementation?No VLANs span the campus network. With the use of multipoint generic routing encapsulation (mGRE) architecture, no changes to the current network wired infrastructure are necessary.
* Manageability for a large WLAN deployment?This solution provides a single point of ingress for both WLAN control and user data into the wired network for which to apply security and quality of service (QoS) policies.
* L3 mobility between floors and across multiple buildings
* The ability to use advanced features on the Cisco Catalyst 6500, which includes other Catalyst 6500 service modules
* Enhanced end-to-end security and QoS by integration with the Catalyst 6500 platform
WDS is used to make a trust relationship (leap username and password) to authenticate the APs.
WDS is used as I told in the first message, for better roaming times 500 mSec down to 250msec. because if he primary WDS AP cache the keys, so when you roam from 1 AP to another and have to be authenticated again you do not have to go over a slow WAN link. the APs that participate in WDS ask the WDS master and get the cashed keys. But WDS is not used in open non encrypted WIFI networks.

The need was to reach an host inside a LAN through a VPN connection managed by the LAN gateway (Cisco 1921).
The LAN gateway performs NAT and there was a dedicate nat rule for the host i wanted to reach through VPN.
