Hi All, I have a question regarding the native vlan in dot1q. Frames comming from the vlan that is choosen as the native vlan is not tagged across the trunk. I can manually set the native vlan to be, say 200. I can then also say that i only want to allow vlan 250 to cross the trunk. I was under the impression that stuff like CDP used the native vlan across trunks, but if it is manually pruned (by not allowing it), why does it still work?
Am I wrong in that CDP does not use the native vlan? What I was trying to do was to follow Cisco's guidelines as to not use the native vlan 1. However, since VTP cant prune vlan 1, I was doing it manually and came up with this thought... Hopefully someone can clear it up for me.
