Questions can lead to answers; it's all good. The servers are on the same vlan. S4 core. We did a wireshark trace and the traffic had no anomalies that I am aware of. The vendor checked it as well and said there were none. CoS has been confirmed via a wireshark on a mirrored IP phone port. We use Cacti and NMS for monitoring our gear.
How did you apply the broadcast limit? Via policy?

Are you do you have an S series core? Have you put a port in that VLAN and run wireshark see if there are any traffic anomalies? Have you done a port mirror on a phone to verify that to COS is being set? How frequantly do you see the issue? What tools do you have for monitoring? We found a MIB for non-unicast traffic that has helped us track down a source for broadcast packets in the past. We ended up applying a limit per port for broadcasts to stabilize our network. Sorry for so many questions. Feel free to call if you want to talk off line. I'm very curious.

The phones Mac auth and get the proper role, which assigns the vlan and CoS.

I cannot confirm or deny whether it is necessary but we went with a seperate vlan per building for voip. For us this means way less than a /24 per building. Although that is how we setup our subnets. We have NAC and we assign a Phones policy with a cos of 6 I believe. No problems. Are you routing at the edge? How so you assign Cos?

We are experiencing jitter on our phones and the CoS configuration on the network side looks fine. I am being told by a telecom vendor that the Avaya phones should reside on a subnet no larger than a /24. Can anyone else confirm or deny this?
