AFM- drop packets in the interface

Hi All,

We have configured AFM in our lab environment, we have already tested the policies and all were working. We also checked the connectivity to the gateway and all are working as well.

Recently, we tried hardcoding the media speed of each interface and from there, we observed the drop packets in the interface. We tried changing the speed to auto but the drop packets are still present.

we also looked at the switch interface statistics and did not see any error/dropped packets.

what I suspect is it was the dropped traffic by FW Policies, but we tried making an accept all rule and put it in as First rule but still, the dropped packets in the interface still increments.

Our question is if it is a normal behavior in the AFM? If not, what may be causing the drop packets?

I hope to get answers as this has been confusing me for days. :(
