I have a question about the native vlan feature on trunks
a simple configuration
switchport trunk native vlan 4
switchport trunk allowed vlan 5,6
in all the labs I could do, this config prevented the native vlan from working on a trunk, but still, out there are a lot of people that claim
that native vlan does not have to be explicitly allowed and that even in the above configuration the trunk works with all vlans.
As I understand correctly this is even cisco's official view, which is wrong!
please, help me figure this out?
