I have a problem with an interface Gi that it has qos enable. It drops packets in priority queue ( cos 5 asignated), following the q2 and there is not drops on q1.
This is the status:
Interface GigabitEthernet9/32 queueing strategy: Weighted Round-Robin
Port QoS is enabled
Trust state: trust COS
Extend trust state: not trusted [COS = 0]
Default COS is 0
Transmit queues [type = 1p2q2t]:
Queue Id Scheduling Num of thresholds
-----------------------------------------
1 WRR low 2
2 WRR high 2
3 Priority 1
WRR bandwidth ratios: 100[queue 1] 255[queue 2]
queue-limit ratios: 70[queue 1] 15[queue 2]
queue random-detect-min-thresholds
----------------------------------
1 40[1] 70[2]
2 40[1] 70[2]
queue random-detect-max-thresholds
----------------------------------
1 70[1] 100[2]
2 70[1] 100[2]
queue thresh cos-map
---------------------------------------
1 1 0 1
1 2 2 3
2 1 4 6
2 2 7

Receive queues [type = 1q2t]:
Queue Id Scheduling Num of thresholds
-----------------------------------------
1 Standard 2
queue tail-drop-thresholds
--------------------------
1 100[1] 100[2]
queue thresh cos-map
---------------------------------------
1 1 0 1 2 3 4
1 2 5 6 7
Packets dropped on Transmit:
BPDU packets: 0
queue thresh dropped [cos-map]
---------------------------------------------------
1 1 0 [0 1 ]
1 2 0 [2 3 ]
2 1 0 [4 6 ]
2 2 486* [7 ]
3 1 486* [5 ]
* - shared transmit counter
Packets dropped on Receive:
BPDU packets: 0
queue thresh dropped [cos-map]
---------------------------------------------------
1 1 0 [0 1 2 3 4 ]
1 2 0 [5 6 7 ]
Thanks,
