For those interested here is how I made it work. I bought two 3550 switch. ISP----Wireless-BH#1----3550#1----Fiber----2950----3550#2----Wireless-BH#2----ISPClients
On the 3550#1 the port connected to Wireless-Backhaul1 I've used the following command. switchport access vlan xx switchport mode dot1q-tunnel l2protocol-tunnel cdp l2protocol-tunnel stp l2protocol-tunnel vtp spanning-tree bpdufilter enable Same thing on the 3550#2 Everything works perfectly.
