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,

Xiao Min
