Hi all,
I have defined a classify table with no session and its acl-miss-next is
drop and assigned it to all interfaces including subinterface. I also
defined another classify table with a session that permit packets with
specific src and dst address according to my intended subinterface. I also
assigned this classify table to all my interfaces including my
subinterface. So, I expect that this subinterface permit packets with
specific src and dst to pass. But it does not happen and I see that they
drop because of the acl set on the parent interface of my subinterface. Why
does this happen? I actually expect that packets match with the second
classify table and its session.
Here is the trace of packet:
Packet 1
06:26:50:769490: dpdk-input

Should I use classify table with l2 option for traffic filtering on
subinterface?
I have defined both of my classify tables with l3 option.
This seems like that the parent interface drop the packet. So, the other
table and session that is intended to match the packets entering the
subinterface never get the packets.
