We're implementing QoS on 6 switches - 4 BD8810 and 2 X480, SW version is 220.127.116.11
The configuration is as follows:
enable diffserv replacement ports
configure diffserv replacement qp6 code-point 46
Then we check queues by issuing "show ports qosmonitor
The interesting thing is that on all BD we see counters incrementing in real-time for QP1 and QP6 as it should be.
But on both X480 despite the same configuration while typing the same command we see only QP1 counters increment while QP6 counters increase only once right after enabling diffserv replacement.
I experimented - cleared the counters and issued "enable diffserv replacement" once again, then checked counters - they again increased only once (some small numbers like 100 packets) and then stop.
I tried to configure diffserv examination on uplink ports but it didn't change the indication of qosmonitor.
Also tried the same on old X450 with 11 version - but the result was the same - it didn't show the increase in QP6.
Have anyone faced the same?
