Also interesting- Cisco catches up with others doing Deep Packet Inspection in Controllers:
Support for Application Visibility and Control (AVC) is introduced. AVC classifies applications using Cisco's Deep Packet Inspection (DPI) techniques with Network-Based Application Recognition (NBAR) engine and provides application-level visibility and control into Wi-Fi network. After recognizing the applications, the AVC feature allows you to either drop or mark the traffic. Using AVC, the controller can detect more than 1000 applications. AVC enables you to perform real-time analysis and create policies to reduce network congestion, costly network link usage, and infrastructure upgrades. • Support for NetFlow protocol is introduced. The NetFlow protocol provides information about network users and applications, peak usage times, and traffic routing. The NetFlow protocol collects IP traffic information from network devices to monitor traffic. The NetFlow architecture consists of the following components: – Collector—Entity that collects all the IP traffic information from various network elements. – Exporter—Network entity that exports the template with the IP traffic information. The controller acts as an exporter. Lee H.

It's OK, upgrading 5508s is one of the lesser painful things I do. Upgrading Prime shouldn't be too bad, either. Patching is a walk in the park. Maybe 1.2 -> 1.3 will come that way...

An interesting snippet from the release notes regarding apple devices... •Support for the Multicast DNS (mDNS) protocol is introduced. Multicast DNS (mDNS) service discovery provides the ability for wireless clients to access Apple services such as Apple Printer and Apple TV advertised in a different Layer 3 network. mDNS performs DNS queries over IP multicast. mDNS supports zero configuration IP networking. As a standard, mDNS uses multicast IP address 224.0.0.251 as the destination address and 5353 as the UDP destination port.
