Well this appears to be a simply amazing product on many many fronts.
While there is still little detail available it simply pulls all your network management into a single platform.
With Cisco Prime NCS you can manage upto 15000 Aironet access points but also upto 5000 autonomous access points.
Most importantly it integrates the management of upto 5000 switches for monitoring and trouble shooting.
Additionally it also integrates with Ciscos MSE and ISE.
Simply phenomenal, I am obviously familiar with the WCS and as always with each new release of WCS there is improved usability and functionality and the NCS looks to pull a whole lot of things into a trully unified management platform.
I really can't wait to get my hands on this and see how much it can actually do in the switched infrastructure.
The hardest part of this will be simply understanding the scale of this behemoth, seeing what new features it includes for the WLAN over and above the WCS and the enhanced WLAN capabilities will be exciting and if it can do some good stuff in the LAN infrastructure too it will simply sell itself and also strengthen the sales arguement for Cisco Unified Networks.
