The North American IPv6 Summit is the largest annual IPv6 event in North America, designed to educate about IPv6 and the current state of IPv6 adoption. We were honored to receive industry recognition of the Cisco’s IPv6 leadership and continued innovation with the Best of Show Award of Product and Service for the Cisco Wireless Controller.
As you read about earlier this summer, Wireless Release 8.0 added a cornucopia of features to our wireless offering, many of which are targeted specifically for upcoming technologies, including IPv6. Let’s look back to see how far we’ve come:
Anticipating the growing demand of the next generation IP and eyeing the arrival of World IPv6 day, Cisco released the first support for IPv6 in its’ Wireless LAN Controller (WLC) software version 7.0 in 2011. There has been a steady progression of feature support ever since. Client mobility appeared in version 7.2 a year later in time to celebrate the launch of IPv6 on the global Internet.Then came the release of 7.4 and it’s support of First Hop Security tools, enabling organization’s to go beyond the lab and deploy IPv6 in a safe, secure manner.

In my previous posts, I discussed with you the importance of unified policy and management as you respond to the bring-your-own-device (BYOD) trend. The Cisco Unified Access solution brings “One Policy. One Management. One Network” to help you with your BYOD initiatives. Today I’ll take a look at the third pillar of Cisco Unified Access, One Network. I’ll explore with you what it means and why it is a critical factor as you take on BYOD.
The workforce is increasingly going mobile. According to research firm Gartner, tablets will be the key accelerator to workforce mobility. A Gartner 2012 report suggested that annual tablet purchase by businesses totaled 13 million units and this number would more than triple to reach 53 million units by 2016. Such rapid mobile growth calls for major wireless network expansion. Market data from Infonetics showed that global wireless LAN equipment sales in the 3rd quarter of 2012 passed the $1-billion mark for the first time. Read More »

So you think you know what BYOD is? Think again!
Cisco Cius - Not BYOD since it's Corporate provisioned.
If you’re a manufacturer you’ve probably heard of BYOD, or ‘Bring Your Own Device’. You know that more and more devices are proliferating throughout the organization. You also know that security is a big issue: How do you stop folks accessing sensitive systems, how do you protect Intellectual Property, and how do you prevent a disastrous shutdown caused by a device either intentionally or unintentionally?
Well, these are only some of the issues -- and they’re rarely addressed by a ‘Good-Enough Network’. Cisco’s BYOD is different -- it looks at the whole picture. It’s not just about your wireless network -- although the Cisco offerings are better than most! It’s about an holistic approach to BYOD. That covers the plant, IT, the LAN and fixed wired network and the wireless network too. All aspects.
As my colleague, Katie Taylor, says in her blog: Read More »

With more than seven billion souls set to tote 10 billion mobile-connected devices by 2016, mobility has not just arrived, it’s taken over our schools, businesses and personal lives.
Just ask Mitch Davis, the CIO of Bowdoin College, a private liberal arts college in Maine. Before BYOD ever became a global IT trend, according to Mitch, the vast majority of college students were already bringing their personal devices into the campus environment.
These co-eds expected Bowdoin to fully embrace personal mobility, and, upon graduation, these same post-grads expect that their employers will do the same (this year’s Connected World Technology Report findings back this up, with more than 40 percent of recent college graduates/Gen Y employees choosing BYOD flexibility over higher pay).
Bottom line, the rules of the game are changing, and companies must move beyond basic BYOD connectivity to meet employee demands today and tomorrow. To help companies meet these demands, we’ve introduced a comprehensive approach that unifies policy, supports a better user experience and simplifies management to deliver an uncompromised user experience in any workspace. After all, Cisco wants to empower IT managers to allow employees to have their devices and use them too. That means delivering:
- A unified security policy across the whole organization – wired, wireless, VPN and now MDM – helping companies set and enforce policies;
- An uncompromised user experience over the entire wired/wireless network, across any type of device; and,
- Simplified operations and network management to understand application performance from a user’s perspective, accelerating troubleshooting and lowering operating costs.
Like Ray-Ban aviators, BYOD is here to stay. And done the right way, BYOD demands a comprehensive approach to allow current and future employees to work how they want, when and where they want, and on the devices they want – while still allowing IT the control and visibility to sleep at night.

By the way, whether you’re a college student or have been working for 30 years, you’re eligible to take the BYOD Challenge and win a trip to 2012 London Olympics – good luck!

Not too long ago I was assigned to a troubleshooting and remediation project for a hospital here in the SF bay area. The problem, after much troubleshooting and lab recreations, was determined to be due to an unique issue with client roaming and authentication. During the course of troubleshooting my coworker and myself often found ourselves explaining 802.1X and 802.11i to others working on the troubleshooting effort, or requesting technical updates. So based on that experience, I started thinking this might a be a good topic to cover here.
Let’s review the some of typical components of the enterprise wireless security model.
What is 802.1X?
802.1X is not a protocol, but rather a framework for a “port-based” access control method. 802.1X was initially created for use in switches, hence the port-based terminology, which really doesn’t fit too well in wireless since users don’t connect to a port. In the end it’s meant to be a logical concept in the 802.11 world. 802.1X was adopted for wireless networks with the creation of 802.11i to provide authenticated access to wireless networks. At a high level. the framework allows for a client that has connected to the WLAN to remain in a blocked port status until it has been authenticated by a AAA server. Essentially the only traffic allow through this virtual blocked port is EAP traffic, things like HTTP would be dropped.
What is EAP?
EAP (Extensible Authentication Protocol) is the authentication method used by 802.1X. It can take on various forms, such as PEAP, EAP-TLS, EAP-FAST, to name a few. There is one thing to remember when determining what EAP type to use in your network, is that it is dependent upon what your client and AAA server supports. This is it, your AP or AP/Controller hardware or code version will play no part in version is supported. Unless your AP/controller is acting as the AAA server, but I’ll stay away from that in this post. I think this can be a point of confusion for people who haven’t read much or anything about EAP methods. So, if some one asks what version of EAP the AP will support, all you need to do is ask them, what does their Client and AAA server support.
What is 802.11i?
Simply put, 802.11i is an amendment to the original 802.11 standard to address the well documented security short comings of WEP. It incorporates WPA as a part of the 802.11i amendment and adds the fully approved WPA2 with AES encryption method. 802.11i introduces the concept of a Robust Security Network (RSN) with the Four-way handshake and the Group key Handshake.
