Dan, Most likely what you would want to do is to implement an hierarchical QOS policy using a parent shaper, and in the child policy put the VOIP traffic in the priority queue, while the rest of the data in its respective queues (high priority data, bulk transfers etc).
The reason for the need for such a shaper is to allow the network to "know" how much bandwidth you really have downstream, or else nothing would stop the traffic from bursting to the physical line rate of the link (which is 100M or even 1G), while your real downstream bandwidth is 70Mbps. In such cases traffic would be dropped on the wireless bridge, and it does not have any awareness of which traffic class the packets being dropped belong to, so it would drop some data packets and some voice packets. Unfortunately, the Cat 3560 is the wrong tool for the task... I would suggest you look at either using a "real" router (like the 2900/3900 series) or maybe a metro switch (ME3600 could be a great option). Note that the same functionality has to be implemented on both ends of the link. This is a common problem, and is generally called "sub rate links" This is another reference: http://www.gossamer-threads.com/lists/cisco/nsp/94076 Arie -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Dan Letkeman Sent: Wednesday, August 17, 2011 04:48 To: cisco-nsp Subject: [c-nsp] remote location voice qos with switches Hello, I have a remote location, where I have a 3560 which connects to our main location via a wireless bridge and goes into a 3560G. The wireless bridge has approximately 70mbps throughput. This remote location has about 12 7962 phones, and for the most part everything works fine, except when some of our I.T. staff are doing large backups or copying images across the link. What would be the most simple qos config to solve the data transfers from hogging the link? Or maybe not qos, maybe just policing? Thanks, Dan. _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
