Hello,
I'm currently having a question regarding ConnectX4 VPI cards.
I have test environment with connectX4 EDR card, and I would like to test some per VL QoS.
Basically, I have 7 client accessing 1 server, and I would like to dedicate some bandwidth to each client.
My computer are running Centos7.1 with MLNX_OFED_LINUX-3.1-1.0.3 (OFED-3.1-1.0.3).
Regarding the Product description of ConnectX4, the card should support 8 VL, so on the paper, everything is ok.
My HCA details are :
HCA : ibv_devinfo
hca_id: mlx5_0
transport: InfiniBand (0)
fw_ver: 12.12.1100
node_guid: e41d:2d03:00f2:9fb4
sys_image_guid: e41d:2d03:00f2:9fb4
vendor_id: 0x02c9
vendor_part_id: 4115
hw_ver: 0x0
board_id: MT_2180110032
phys_port_cnt: 1
port: 1
state: PORT_ACTIVE (4)
max_mtu: 4096 (5)
active_mtu: 4096 (5)
sm_lid: 1
port_lid: 15
port_lmc: 0x00
link_layer: InfiniBand
On the wire, I see that :
# smpquery PI 15 1 | grep .VL
VLCap:...........................VL0-3
OperVLs:.........................VL0-3
So the card is only supporting 4 VL.
What can I do to get 8VL functionning ?
Thanks,
Jerome
