Notes on Layer 3 QoS Packet Marking Enhancements
•
Layer 3 QoS is not supported when using Layer 2 LWAPP. 802.1p tagging must be used for QoS marking to ensure that packets receive the
proper level of QoS.
•
The Layer 3 QoS packet marking translations are not configurable.
Benefits of Layer 3 QoS Packet-Marking Enhancements
•
Ensures that packets receive the proper QoS handling from end to end.
•
Policing of 802.11e UP / 802.1p and IP DSCP values ensures that wireless endpoints conform to network QoS policies.

Guest Tunnel Origination for Cisco 2000 Series Wireless LAN Controllers
The Guest Tunneling feature was first introduced in Cisco Unified Wireless Network Software Release 3.0 and provides additional security for
guest-user access to the corporate wireless network. For a complete description of the Guest Tunneling feature, refer to the Cisco Unified Wireless
Network Software Release 3.0 Product Bulletin (
http://www.cisco.com/en/US/products/ps6366/prod_bulletin0900aecd802d2742.html
). In Release
3.0, this feature was not available on Cisco 2000 Series wireless LAN controllers. Release 3.2 adds support for the Cisco 2000 Series to originate
guest tunnels. This capability is also available on the Cisco WLCM for integrated services routers. As these platforms are typically deployed in
remote offices, the ability to originate guest tunnels from these controllers to a guest controller in the DMZ provides a flexible and secure way to
provide guest access in remote offices.
