Hello, 

We are using following SRIOV NICs in our platforms.

[root@appliance-1:Active] ~ # lspci -d 8086:1893

The nics are binded to iavf drivers. please find the driver details.

Scenario:

On the platform/host, We have created a LACP LAG on the PFs.

Creating a container allocating a vf from each PF using sriov CNI and creating the LACP using the  bond CNI. We see that interfaces and Bond is created successfully inside the container. 


We have followed this doc to configure LACP inside the container:
https://www.intel.com/content/www/us/en/developer/articles/technical/bond-cni.html

 

Issue:
We have observed that LACP is not formed properly with VFs inside the container. 

The traffic doesn't passthrough from the container. 

Please let us know if you need any more details on the config and setup.
