Native vlan packets are sent untagged & it's not needed to allow specifically through the trunk.
We can change native vlan number (in fact we have 2 different vlan numbers at two end switches) & it works fine. native vlan number isn't sent in packets. (if you configure 2 different native vlans in 2 ends you will get a CDP error message) You need to change native vlan if you want to send vlan 1 with a tag ( eg: you need CoS markings to be preserved) Ken On Thu, May 10, 2012 at 1:55 PM, imad Abdallah <[email protected]>wrote: > > Hi,I'm bit confused regarding native vlan and trunk allowed vlan.
