Stripping specific VLAN tag at core switch
We have numerous Allied Telesis 8000GS/24's at the edge and an x908 core switch.
I haven't looked into it before outside of standard tagged/untagged VLANs but what we want to do is tunnel traffic from certain edge ports to the core switch without wasting ports linking back into the general LAN.
For example from a Wireless Bridge to a remote building we want the traffic to go back to the core switch without being passed around other switches (such as if there is large amounts of broadcast traffic being transmitted.
i.e.
Wireless Bridge to an untagged port on the switch,
Switch to the core (VLAN Trunked)
Core strips the VLAN and allows traffic to be redistributed as required.
95% of the traffic will be transmitted to the core switch from the far wireless bridge end.
The madness behind this is that later there will be extended routing and security layers built for certain connections/VLANs but we want to start getting the base for this underway with the configurations on the edge switches so we can later concentrate on the core and router.
Clear as mud?

Hi ArneLovius. Damn - I was sure I attached a diagram....
Will try to do it again & attach.

I'll escalate this question to Allied Telesis and close it.
Thanks for trying :)

I believe I described how to eliminate broadcast traffic from the wireless devices.
The exact desired functionality as described by the original poster is not technically feasible, so I provided a method to limit the broadcast traffic, which is the end result he desired.

The Wireless link passes all traffic and at each end (port interface on the switch) they are set to VLAN Trunk so all except the default VLAN traffic is tagged.
Thinking from another perspective about the issue, you are correct that it is not technically feasible as even if the core switch was set up to strip VLAN tags on ingress, it would not know what to do in egress.
Due to your input however asavener I will assign points as you were correct about the problem but indeed there is no direct solution.

There will be a way to do this in the future using OpenFlow. Although Allied Telesis don't yet support OpenFlow on their AW+ Router OS, it may be the case in the near future that they will.
a diagram might be useful
