My company has some VC equipment connected over a WAN - There are three sites which connect via a mangaged MPLS network.
We've had issues with quality and the supplier recommends trying some QOS.
My question is where to place the QOS?
Each set up goes Cat Switch (3700 series) > WAN router. Should the qos ideally be placed on the router or the switch before it?
Any advise would be much appreciated.
