Hello,
DPM controls turning QOS on and the OS takes it from there. QOS is not a garuantee that you will always get "x" amount of bandwidth but rather a negotiation.
Questions:
1.) Is the BMR for the same server or another server?
2.) If you look at the MSDPMCurr.errlog what do you see as the negotiaged QoS settings?
Example:
[4]<PID>.4124 07/08/2010-18:35:38.332 [ENGINE
cc_base.cpp@1040] Created Socket with Family: 2,
QoS Index: 5
[3]<PID>.4124 07/08/2010-18:35:38.391 [ENGINE
endpoint.cpp@422] DM: EndPoint successfully created using port#5718
Note the QoS port number 5718.

All the network elements along the path that prioritized traffic takes must support QoS. Such network elements include the sending and receiving hosts, Layer 2 (Data Link layer) network devices (bridges and switches), and Layer 3 (Network layer) network devices
(routers), including routers used for wide area network (WAN) links. If a network device along this path does not support QoS, the traffic flow receives the standard first-come, first-served treatment on that network segment.

Most modern enterprise routers support DSCP traffic differentiation, but it is typically disabled by default. During forwarding, DSCP-capable routers read the DSCP value and place the packet into a specific queue.
Thanks
