I am having a strange issue with QoS on some 3850's we are installing. Below is an excerpt from the config. I have two class-map's. One that matches ef for Voice and one that matches af41 for VIDEO. Then two classes that allocate 1 percent to voice and 5 percent to video. I then have a service policy on all users interfaces "service-policy output USER".
The issue i am seeing is when the class VIDEO is in place ALL bulk data traffic (like a file transfer from a file share) drops to about 5Mb/s. I have ran a wireshark capture and packets coming from the file share have a DSCP of 0. So i cannot explain why that data would be hitting the Video class and getting throttled down. Does anything with the below config look incorrect?
class-map match-any VIDEO
match ip dscp af41
class-map match-any VOICE
match ip dscp ef
class-map match-any non-client-nrt-class
match non-client-nrt
policy-map UPLINK
class VOICE
priority level 1 percent 10
police cir percent 10 conform-action transmit exceed-action drop
