    Hi, 

    We have sflow configured on HPE-5945 Stacks and are able to collect the interface sflow on the IMC NTA no problem

    However, I cannot see how we activate sflow on the VxLAN configuration within the HPE 5945 config

    Their HPE IMC Server has a section for collecting VLAN/VxLAN within the IMC NTA settings. We have done that, but are not collecting any VxLAN traffic

    Maybe I'm misunderstanding the capabilities.

    It seems you can only enable sflow on the physical interfaces of the HPE 5945 switches ? 

    I think IMC is only able to collect VxLAN flow traffic when the IMC itself has pushed those VxLAN settings to the switch ??

    Any help or pointers would be appreciated

    Thanks

    Ger
