Mention Network Access Control (NAC) to some security or network operations engineers, and they just might grimace. Why? Most people still associate NAC with a set of technologies that were complicated to deploy and implement effectively.
Today, however, those nightmare assumptions are far removed from the reality. In this newly released white paper, Jon Oltsik, Senior Principal Analyst for the Enterprise Strategy Group, discusses how NAC is transforming into something more—a technology he calls Endpoint Visibility, Access, and Security or EVAS. Mr. Oltsik discusses how the NAC market has changed to reduce complexity in both deployment and usage. Through this advancement, this evolved technology has become an increasingly more critical component in securing enterprise networks. In addition, Mr. Oltsik discusses how Cisco and the Cisco Identity Services Engine (ISE) are in the best position to meet IT security challenges in terms of what EVAS should be and how it helps.

Just released yesterday: Cisco Wireless Release 8.0 includes a feature called Receiver Start of Packet (RX-SOP), which you can think of as putting earmuffs on the access point. It’s not a new feature, as it has been used in stadiums and other high density deployments to great success for several years. WLC 8.0 adds GUI configuration support with a low, medium, and high setting.
RX-SOP is meant for dense deployments, where channel reuse is a concern. It’s a way to shrink cell sizes, but be careful: too much SOP and you can shrink your cells to the point where clients are no long able to connect.
Check out this whitepaper from the guys at the No Strings Attached Show. It provides detailed configuration guidance as well real-world data–even the actual config.
For those of you interested in the nitty-gritty of how RX-SOP works, we had one of our RF Technical Leaders, John Blosco, go in-depth at Wireless Field Day 7. If you missed it, here’s the video:

A FlexPod has the power to leap tall buildings in a single bound, and it’s more powerful than a locomotive. No wait, that’s Superman. But FlexPods are going strong in the marketplace—and they are currently sold by 120 partners and counting.
The mighty FlexPod is also the subject of a recent whitepaper by IDC titled “Accelerating Converged Infrastructure with the FlexPod Datacenter Solution and the Support Alliance.” Cisco Partner IronBrick spoke to IDC for the white paper about its experience selling FlexPod and provided some insights on what their customers are looking for.
IronBrick customers are seeing “rapid data growth, have concerns around operational and resource limitations, have physical datacenter issues regarding space, power, and cooling, and have the desire to deploy IT solutions that enable nimble response to today’s dynamic and fast-moving application demand,” according to the whitepaper.
So guess what satisfies all of their customer needs? Read More »
