VLAN problem

Hi,
I have some troubles with VLANs on MT…

Facts:

  • cisco switch connected with ether1 of MT box (2.9.44).
  • switch’s port set to trunk mode, native (untagged) VLAN310 , 400 as tagged vlan.
  • VLAN400 interface created on ether1 of the MT box. A virtualAP created, a EoIP tunnel created to a client attached to the virtual AP. Tunnel and VLAN400 interface assigned to a new bridge.

I verified that VLAN400 tagged packets go out of the MT via ether1 but no VLAN400 packet goes to VLAN400 interface of the MT from outside (no Rx packet counter change, no packets visible in sniffer, no ARP entries added, etc). I can see VLAN 400 tagged packets (sniffer on ether1 of the MT box) - so they are delivered by the switch port to the MT box. I tried to assign an IP to VLAN400 interface on MT but it is not accessbile from other devices in VLAN 400 too. It seems like the VLAN400 interface is not picking VLAN 400 tagged interface from the ether1.
There is no problem with native (untagged) packets…

Thanks

SOLVED: just to be sure the interface you are creating VLANs on is not part of any bridge. I though the VLANs will remove the packets with appropriate VLAN tag and the rest of the packets will be bridged. But inthe facts if the bridge will get all the packets (even tagged ones) and the VLAN interfaces will receive no packets
