Querying Interface Traffic

You can check whether the switch configuration takes effect on the service side by checking whether there is traffic on interfaces.

1. Configure queue priorities for RoCE NICs on all nodes.
   

   Even if you have bonded two interfaces (mode 0/2/4), you still need to configure the priority for each interface to achieve optimal network performance.

   1 2	mlnx_qos -i enp133s0f0 -f 1,0,0,0,0,0,0,0 mlnx_qos -i enp133s0f1 -f 1,0,0,0,0,0,0,0

2. Check whether the configuration is successful.

   mlnx_qos -i enp133s0f0
   mlnx_qos -i enp133s0f1

   

3. If the lldpad warning is generated, disable the lldpad service and perform the preceding configuration again.

   

   systemctl stop lldpad
   systemctl disable lldpad

4. Check whether there is traffic on the NIC. If the returned traffic changes, there is traffic on the NIC.

   1 2	watch -n 1 "ethtool -S enp133s0f0 | grep prio" watch -n 1 "ethtool -S enp133s0f1 | grep prio"
