Dear Xiao, Correct. Obviously this will be exported per flow and the interface entities have to be key fields as the flow entities as well.

Hi Thomas, If I understand you correctly, you mean the IE exporter can use ingressInterface/egressInterface to indicate LAG port and ingressPhysicalInterface/egressPhysicalInterface to indicate LAG member port, so the receiver can deduce the implicit meanings of them if they have different values, is that right?

Where ingressInterfaceType and egressInterfaceType, which references to https://www.iana.org/assignments/ianaiftype-mib/ianaiftype-mib, is describing what type of interface it is. I would expect in a LAG configuration that the lag interface is ingressInterface resp. egressInterface and the member interfaces are ingressPhysicalInterface resp. egressPhysicalInterface. I hope that helps.

Hi authors, At the request of Giuseppe, I had a read on draft-gfz-opsawg-ipfix-alt-mark-00. There are IPFIX IEs ingressInterface, egressInterface, ingressPhysicalInterface and egressPhysicalInterface, is there an IE indicating a LAG interface? Best Regards, Xiao Min
