Configuring QOS for Lync on a cisco 2851 router

Posted on 2014-09-10
Medium Priority
Last Modified: 2014-09-11
I am trying to get an understanding of how to configure QOS for Lync voice calls to give them priority when exiting my network and going out over the WAN.  Fairly new to configuring QOS on routers in general.  Any help would be appreciated.

I see this request often, and will give you my opinion, with some assumptions.

I am going to assume your network is not the bottle neck for voice?

QoS only works when you control both ends.  The internet does not honor QoS tags so you would not benefit from QoS tagging.  You never know the route the packets will travel and get the benefit every device would have to be under your control to use.

Traffic shaping would help at the router

OK. I am currently doing traffic shaping with an Exinda. I will look into doing this at the router level also.

Do you have any good web links referring to traffic shaping on the cisco 2851?
