i got a vm that works fine when its on vlan50 portgrop on the nexus 1000v but hen the vm migrates to another esxi host, it hass no network access. I checked the service profile and both hosts has the same profiles and vlans.

 

I tried another vlan and it works on both hosts. the nexus s1000v vnics also have the same vlans on both hosts.

 

Cant figure out why this one esxi host cannot let the vm get out on this vlan 50

Looks like I fixed he issue. I had o put in 

 

switchport trunk native vlan 50 

 

on the uplink of the nexus 1000v. 

 

but how come one host works fine and another does not work without this line on the uplink?
