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.

Correcting the email address [e-mail].


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?


Cheers,

Xiao Min

Dear Xiao,

I agree that the description and the additional information does not provide information to distinguish between

ingressInterface, egressInterface

and

ingressPhysicalInterface, egressPhysicalInterface

However from an implementation perspective I have observed that in all cases ingressInterface and egressInterface refer to logical and ingressPhysicalInterface and egressPhysicalInterface to physical interfaces.

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.

Best wishes
Thomas

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,
