[Z9332][202012]: PFC WD is not working in 202012 images.
This is seen after inclusion of PR https://github.com/Azure/sonic-swss/pull/1111 in 202012 branch.
Without the PR changes ( with older version of pfc_detect_broadcom.lua) , PFCwd works fine.
Steps to reproduce the issue:
Enable PFCwd with drop action
Send P3 Traffic from Port 1 to port2
Send PFC pause for P3 from Port2 to port1 .
Describe the results you received:
in Latest image
When PFC pause frames are received, instead of dropping packets at the device , the PFC pause frames are transmitted to the Ingress port .
