I have a Cisco 3850, and everything between my two vlans is just happy with ports being trunk and having a vlan of 30 with a native VLAN of 1. Inter VM communication stops working if I change the native VLAN to 30. I have the vswitch in esxi properly tagged as 30 as well. But if I don't change the native VLAN, the Cisco that I'm trying to add to the network complains about a mismatched native VLAN on my original switch. I'm newish to networking so I'm just kind of at a loss as to why this is being difficult edit: Changed duplicate to mismatched.
