As Wi-Fi continues to be the primary mode of access, enterprise Unified Communication(UC) applications usage is increasing with smartphones, tablets and laptops.
Customers are asking, is there anything I can do to prioritize Jabber or Lync traffic over others or even identify how much of the traffic is really collaboration traffic vs. other types of media. The recently introduced Wireless Release 7.6 enhances the ability to classify Microsoft Lync 2013 and Jabber with Cisco WLAN Infrastructure.
In the first blog about Application Visibility and Control over Cisco WLAN, I captured what is AVC and the capabilities included in the release 7.4. In a subsequent blog, I had captured a success story about a customer who benefited from the reliability by deprioritizing scavenger level applications as well as captured highlights of the enhancements in release 7.5. This blog captures how the release 7.6 allows popular collaboration applications to be accurately classified and prioritized as well as provides a teaser to some of the innovations that can be expected in the future.
What exact capabilities AireOS 7.6 provide ?
The protocol pack 6.3 introduced in AireOS 7.6 allows you to identify and prioritize not just Jabber but also sub-classify Cisco Jabber Audio, Cisco Jabber IM and Cisco Jabber Video. Customers may want to prioritize the Cisco Jabber Audio as the highest priority while the others may be lower priority. Similarly you can classify not just Microsoft Lync but also Microsoft Lync Audio, rtcp and Microsoft Lync Video and thereby prioritize them separately. Read More »

If you’ve been a long time user of Wi-Fi, at some point you have either observed someone encounter (or have personally suffered from) so called “sticky client syndrome”. In this circumstance, a client device tenaciously, doggedly, persistently, and stubbornly stays connected to an AP that it connected to earlier even though the client has physically moved closer to another AP.
Surprisingly, the reason for this is not entirely…errr…ummm…unreasonable. After all, if you are at home, you don’t want to be accidentally connecting to your neighbor’s AP just because the Wi-Fi device you’re using happens to be closer to your neighbor’s AP than to your own.
However, this behavior is completely unacceptable in an enterprise or public Wi-Fi environment where multiple APs are used in support of a wireless LAN and where portability, nomadicity, or mobility is the norm. In this case, the client should typically be regularly attempting to seek the best possible Wi-Fi connection.
Some may argue that regularly scanning for a better Wi-Fi connection unnecessarily consumes battery life for the client device and will interrupt ongoing connectivity. Therefore the “cure is worse than the disease”. But this is true only if the client is very aggressively scanning and actually creates the complete opposite of being “sticky”.
The fundamental issue with “stickiness” is that many client devices simply wait too long to initiate scanning and therefore seeking a better connection. These devices simply insist on maintaining an existing Wi-Fi connection even though that connection may be virtually unusable for anything but the most basic functionality. Read More »

There have been a lot of fantastic moments shared between family and friends over Cisco ūmi. People have used umi to transform their HDTVs to bring the family together for a reunion, to broadcast first steps for the grandparents, or even to get a violin lesson from a former teacher. We thank the ūmi community for sharing these stories with us and we look forward to hearing many more.
But even better is when you share how you’re using ūmi, through ūmi! We were so thrilled when a user shared a ūmi video with us that we decided to open up our own ūmi account and welcome videos from all users. Whether your band wants to perform an impromptu concert, you want to share how you virtually met your new nephew or you want to tell us what you think of HD video chatting, we want to hear from you! And you can also use this number to test out your Cisco ūmi system.
