I have wireless access points that I want to switch the native vlan on. If I have vlans on my edge switch of 5, 10, and 15, and I set my native vlan as 5, my guest as 10 and secured as 15, what happens to the "native" traffic when it leaves that switch, and into another switch that has it's native as vlan 1?
WAP Native (5) -> switch (5)(native 1) -> switch (native 1)
Do I have anything to worry about? I figure that since the traffic is leaving out the native vlan, so it really shouldn't matter what the vlan is that I specify as the native. From a device that attaches to the switch perspective, theoretically I can have multiple native vlans, correct?
The native vlan concept is very local and confined to a single link.
The second switch knows that frames that arrive on left link are untagged when they belong to Vlan 5, so its action will be to send out frames with vlan tag 5 if that vlan is permitted and in STP forwarding state on the right link.
So with this setup you are not joining two broadcast domains.
so yes, you can use different native vlans on different ports, the two endpoints of the same link need to agree on the native vlan-id.
Hope to help
