Hello,


We are trying to test the meter mark feature with the testpmd but we are observing some unusual results. We are trying to send different color packets to different queues but we are not seeing the desired results


Supporting INFO


    MT2892 Family [ConnectX-6 Dx]

    Driver: mlx5_core

    Version: 5.8-1.1.2

    Firmware-version: 22.35.2000 (MT_0000000436)

    dpdk- 22.11


Here are our test steps

Step 1: Configuring meter_mark in testpmd:

sudo ./build/app/dpdk-testpmd -l 0-3 -n 4 -a 0000:4:00.0,dv_flow_en=2 --file-prefix ts -- -i --disable-rss --txq=9 –rxq=9

port stop 0

port configure

flow configure 0 queues_number 9 queues_size 256 meters_number 1


Pattern template configure


flow pattern_template 0 create pattern_template_id 2 relaxed true ingress template eth dst is 00:16:3e:31:15:c3 / end

flow pattern_template 0 create pattern_template_id 4 relaxed true ingress template meter color is green / end

flow pattern_template 0 create pattern_template_id 5 relaxed true ingress template meter color is yellow / end

flow pattern_template 0 create pattern_template_id 6 relaxed true ingress template meter color is red / end

Action Template configure

flow actions_template 0 create actions_template_id 1 template jump group 1 / end mask jump group 1 / end

flow actions_template 0 create actions_template_id 2 template meter_mark mtr_profile 0 mtr_color_mode 1
mtr_init_color green mtr_state 1 / jump group 2 / end mask meter_mark mtr_profile 0 mtr_color_mode 1 mtr_init_color green mtr_state 1 / jump group 2 / end

flow actions_template 0 create actions_template_id 4 template queue index 2 / end mask queue index 2 / end

flow actions_template 0 create actions_template_id 5 template queue index 6 / end mask queue index 6 / end

flow actions_template 0 create actions_template_id 6 template drop / end mask drop / end

Template Table creation


flow template_table 0 create table_id 1 group 0 ingress rules_number 10 pattern_template 2 actions_template 1

flow template_table 0 create table_id 2 group 1 ingress rules_number 10 pattern_template 2 actions_template 2

flow template_table 0 create table_id 4 group 2 ingress rules_number 10 pattern_template 4 actions_template 4

flow template_table 0 create table_id 5 group 2 ingress rules_number 10 pattern_template 5 actions_template 5

flow template_table 0 create table_id 6 group 2 ingress rules_number 10 pattern_template 6 actions_template 6

port start 0

profile creation for meter mark

add port meter profile trtcm_rfc2698 0 0 120 250 20 3000 0

Flow queue creation

flow queue 0 create 0 template_table 1 pattern_template 0 actions_template 0 postpone 0 pattern eth dst is 00:16:3e:31:15:c3 / end actions drop / end

flow queue 0 create 0 template_table 2 pattern_template 0 actions_template 0 postpone 0 pattern eth dst is 00:16:3e:31:15:c3 / end actions drop / end

flow queue 0 create 0 template_table 4 pattern_template 0 actions_template 0 postpone 0 pattern meter color is green / end actions drop / end

flow queue 0 create 0 template_table 5 pattern_template 0 actions_template 0 postpone 0 pattern meter color is yellow / end actions drop / end

flow queue 0 create 0 template_table 6 pattern_template 0 actions_template 0 postpone 0 pattern meter color is red / end actions drop / end


Push/Pull operation


flow push 0 queue 0

Queue #0 operations pushed

 flow pull 0 queue 0

Queue #0 pulled 2 operations (0 failed, 2 succeeded)


After pulling the flow rules it was observed that only 2 rules were successfully pulled


initially, after sending 2000 packets of 64 bytes from pktgen we saw only 1 packet received on queue 2 even though  only 2 rules were successfully pushed and pulled from the nic
