In the previous blog, we covered details about Cisco AVC enhancements with AireOS 7.6 that allow you to classify various collaboration applications such as Cisco Jabber™, Cisco WebEx®, Microsoft Office 365, Microsoft Lync, and Microsoft Skype. Many customers have deployed voice-over-WLAN in mission-critical environments. The goal in this blog is to walk you through the collaboration specific enhancements implemented since then, that enable customers to get a great experience when supporting Microsoft Lync over Cisco WLAN.
The above picture shows the timeline for various AVC, policy and Lync enhancements. The crucial updates since AireOS 7.6 are:
- Nov 2013: Cisco WLAN achieves Microsoft Lync Certification for 802.11n and white paper with best practices with Cisco WLAN and Microsoft Lync.
- Aug 2014: With AireOS 8.0, Cisco WLC allows you to configure per user-group, per device-model policies
- In Progress: 802.11ac certification for AireOS & IOS
- H1 CY15: Cisco to introduce Microsoft Lync SDN interoperability with the upcoming AireOS release. This software update on the Wireless LAN Controller will allow you to view statistics about Lync call quality adjacent to relevant WLAN Statistics.
This capability allows you to troubleshoot Lync issues on the Wireless LAN Controller to identify if poor MOS scores are due to one of these issues:
- Wireless coverage holes
- Non-Wi-Fi interference
- Over-loaded Wi-Fi channel or over-loaded Access Point
- Client-side issues
If you have a Cisco Prime Infrastructure in your network, you can use the robust capabilities of this network management tool to understand network topology and isolate if the issues are over the WAN, LAN or WLAN.
