Lync Deployment Best Practices

DEPLOYMENT GUIDE
Lync Deployment Best Practices
INTRODUCTION
Microsoft Lync is an enterprise-ready unified communications platform that connects people on a
wide variety of operating systems and endpoints, including laptops, desktops, tablets, and mobile
devices. Lync provides a consistent, single-client experience for presence, instant messaging, voice,
and video, and offers a great meeting experience. Lync enables rich communication with hundreds of
millions of people around the world.

This document provides best practices for configuration and deployment of Microsoft Lync on a Meru
wireless network. It assumes that the reader is experienced in Wi-Fi design and deployment and
has worked with Meru products. It also assumes there is a working Lync system over a Meru WLAN
infrastructure.
BEST PRACTICE RECOMMENDATIONS FOR
LYNC DEPLOYMENTS
RECOMMENDED STATION CONFIGURATION:
•Stations should be WMM capable.
•Stations should set DSCP and 802.11e values for voice, video, and background traffic.
RECOMMENDED MERU CONFIGURATION:
•Meru System Director Version 6.1.2 or higher must be running in the deployment.
•Enable “Voicescale” feature in the controller.
(Refer to steps below for how to enable/disable Voicescale feature in the Meru controller).
•If required, enable Traffic shaping for background traffic using Meru QoS rules.
(Refer to the Meru Configuration Guide or Help page for how to create QoS rules based on IP
address, port numbers, protocol, and enabling traffic shaping.)
•The default deployment configuration is Tunneled mode, and this is recommended for Lync
deployment. If the deployment requires the AP to support 802.11e (WMM) to 802.1p (Priority
Tag) mapping, and vice versa, configure the AP in the Bridge mode. (For additional details,
please refer to the steps below, or to the Meru Configuration Guide or Help page: “How to
configure AP in Bridge with static and dynamic VLAN with AP VLAN priority.”)
•If clients don’t support DSCP tagging (see Recommended Station Configuration
section above), Meru QoS rules for DSCP tagging can used as an alternative.
(Refer to the Meru Configuration Guide or Help page: “How to create QoS rule based on IP
address, port numbers, protocol, and tag DSCP value.”)
CONFIGURATION GUIDELINES FOR IMPLEMENTING THE RECOMMENDATIONS:
Enabling/disabling Voicescale feature:

REQUIRED
COMPONENTS
¾¾ Microsoft Lync
Server 2013: Real-time
communications server
software that provides
the infrastructure for
enterprise unified
communications.
¾¾ Microsoft Lync
Client: Lync 2013
provides a single,
unified client for realtime communications,
including voice and
video calls, Lync
meetings, presence,
instant messaging, and
persistent chat.
¾¾ Meru Controller:
Meru WLAN controllers
optimize traffic across
wireless access
points (APs) and client
devices to deliver
high performance and
predictability while
addressing missioncritical enterprise
demands for wireless
connectivity.
¾¾ Meru Access Points:
The Meru AP832
and AP822 are
802.11a/b/g/n/ac WLAN
access points that
can meet the highest
performance wireless
requirements with gigabit
speeds.

CONCLUSION
The Microsoft Lync platform provides a variety of capabilities for unified communications. The Meru WLAN infrastructure delivers
high-performance wireless connectivity to support data, voice, and video applications with superior predictability and reliability. The
recommendations and configuration guidelines provided in this guide will help ensure an extraordinary unified communications experience
for Lync users.
