NSX VDS, Logical Switch and Uplink

  • 1.  NSX VDS, Logical Switch and Uplink

    Dear Community Member,

    I want to seek your help to understand when the VM to VM traffic will use VXLAN. I did below test

    1. My Web1 and Web2 running on different ESXi but on same Logical Switch, the Logical Switch is using Uplink1

    2.At the same time, my VXLAN kernel on the two ESXi are using Uplink2

    3. Web1 is able to ping Web2

    4. Web1 not able to ping Web2 if I remove uplink1 from Logical Switch portgroup teaming setting

    In my mind, Web1 to Web2  traffic will flow though VXLAN which is the vmk1 interface so even the uplink1 is removed they should still able to ping each other via VXLAN.
    Can anyone help me to understand this? Thank you.

    Hello,
    but if the web1 and web2 are in different ESXI , how could they ping each other without a physical connection ?;

    what is your NIC teaming policy?

    Both your uplinks are actively participating in transmitting and receiving traffic for everything attached to the VDS. I assume you have configured a teaming policy?
