I have completed CCNA 3 course and am in 4 right now. I am still confused about VLAN native commands such as
sw tr na vl xxx
When this is on a trunk port, what does it mean?
Another reason if you are one of the people who like to force trunks "on" you better make sure you have the native vlans correct on each end . This won't happen when the trunk is negotiated because it will not create the trunk if the natives don't match . When you force on trunks it will say its trunking as long as you have a layer 1 physical link on the port though the trunk may not be working or working incorrectly.
