Get your Wi-Fi network ready for Windows 8

October 12, 2012 at 5:00 am PST

Microsoft will launch Windows 8 in late October. Along with a slew of other features, it will be among the first to support the 802.11w standard to protect Management Frames for client devices on Wi-Fi networks.

Customers running old Cisco unified releases (between 4.2 to 7.2) in local, Flex or mesh mode will run into an interoperability bug (CSCua29504, to be exact) that prevents 802.11w enabled clients from connecting to a Cisco WLAN with Management Frame Protection (MFP) enabled. This bug does not affect customers running autonomous access point deployments or customers running Cisco unified releases older than 4.2.

What are the possible solutions for you?

1. Please upgrade your production environment to one of the following releases, which will interoperate with Windows 8.

  • 7.3.101.0
  • 7.2.111.3
  • 7.0.235.3

2. Roll back to pre-windows 8 drivers as identified in the Microsoft Knowledge Base article.
3. Fall back to TKIP
4. Sign up for a beta release for Cisco’s upcoming feature release 7.4 (beta available now!) that supports the 802.11w feature in local mode.

What is 802.11w ?

Interoperability is Freedom of Communications

Imagine a world where iPhones can only call other iPhones and Blackberries can only call other Blackberries, and where traditional land-line phones and mobile phones are separate islands of technology.  A world where you need a specific browser for specific web pages, and where you can only send emails to people using the same mail system.This would be a world without interoperability and industry standards.

How can we expect advancements in society (or humanity for that matter), if we can’t communicate with each other, or if technology can’t interoperate with each other?  To achieve this any to any vision we’ve been talking about, or to achieve that ultimate experience where technology just works together and it becomes transparent to what we do every day, we need standards based interoperability.

Get the Most from Telepresence with Cisco Unified Call Control

Ensuring seamless, secure connections over telepresence and video, Cisco Unified Call Control offers a scalable and pervasive collaboration solution. It includes the following:

  • Cisco Unified Communications Manager (CUCM), which delivers key aspects of core call control; and,
  • Cisco TelePresence Video Communication Server (VCS) Expressway, which enables advanced telepresence applications such as secure B2B communication, remote access and firewall traversal capabilities;
    • VCS Expressway also supports H.323 for interoperability and interworking to maximize customers’ investments.

Check out the video below from InfoComm 2012, where I  gave a short overview of how CUCM and VCS Expressway operate together to streamline and simplify the telepresence experience.

Cisco Unified Communications 9.0 – Bridging Systems to Connect Collaboration Experiences

Interoperability. This is a broadly used term in the industry, and at Cisco, we often talk about it in the technical context of the IT stack. However, let’s take a step back and focus on what we want to achieve through interoperability—connecting the right collaboration experiences to the right devices and users.

With Cisco Unified Communications (UC) 9.0 we deliver a series of enhancements that bridge systems, resulting in increased interoperability to enable these critical collaboration experiences.

Many of you are familiar with email-style calling, aka URI (Uniform Resource Identifier) dialing, available if you use our current Cisco TelePresence endpoints. With Cisco UC 9.0, you can now use URI dialing beyond video endpoints. Choose whatever you prefer—an email address or phone number—to Read More »

Making interoperability work in unified communications and collaboration

As we kick off this year’s Enterprise Connect conference, one subject I am discussing a lot with customers is interoperability. This topic is always evolving, but our customers’ need for interoperability has remained the same. So what are the customers telling us about their interoperability requirements and concerns within unified communications and collaboration, and what is Cisco’s approach to addressing those?

What customers want:

At its heart, interoperability is about enabling the free flow of communication across boundaries – whether those boundaries are geographical, across firewalls between businesses and their ecosystems or customers. Customers want to be able to share information quickly and easily across different systems from multiple vendors.

Customers also stress the need for protecting their investments in existing systems and extending their capabilities to new types of work scenarios. These systems include infrastructure (such as Active Directory or Exchange or Notes), voice and video systems (such as Cisco’s Unified Communications Manager and TelePresence and competitive products from other vendors), and desktop or enterprise productivity applications (such as Microsoft Office, IBM Lotus, SAP, Salesforce.com and others). They must work within heterogeneous environments and accommodate new solutions as they come to market.

But that two systems work together is not enough. They must come together as seamlessly as possible to ensure an uncompromised user experience

Finally, this all needs to happen across platforms and devices, particularly as we move toward a post-PC era of many different devices -- from smartphones and tablets in the field to desktop computers and immersive room-based systems. These devices need to be blended into customers’ existing collaboration environments while providing a consistent and compelling user experience.

This is what customers want.
