Hi Guy's,
So I am trying to understand native Vlans in a particular environment. So lets assume my core and switch have trunks with native vlan 111 and allowed vlan 10,20,30)
Now for some weird client request I was asked to create trunks on my switch with a native vlan of 10
So now on the switch all my ports are trunked as Native 10, allowed 10,20,30 except the uplink with the core that stays the same.
The client wants to be able to bring up nodes through untagged traffic on vlan 10 through an ESXI environment(Nutanix to be specific).
My question is: Can the untagged traffic from vlan 10 go to my core? I believe it can but I would like confirmation.
Would there be a way to prevent it from going to the core short of removing vlan 10 from the trunk to the core?
Servers --------- Trunk(native10, all 10,20,30) - - - - - - - - - - --Switch --------------Trunk(native111), allowed 10,20,30) ---------- Core
Thanks
