Got it. Thank you Thomas!
If some text can be added to clarify this usage of ingressInterface/egressInterface and ingressPhysicalInterface/egressPhysicalInterface, that would help the implementer.

Cheers,
Xiao Min

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.

 
Best wishes

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,
