At a customers site we (I) setup a "WLAN-bridge"as a backup-link/redundancy för a fiber-connection between the main office and the wharehouse, a distance of approximately 500 meters.
The bridge consists of two AP1240BG and external panel antennas and the customer wants to bridge 16 VLANS across the air in case of a broken fiber.
When we had installed the link and tested it, by disconnecting the fiber (Gi0/1) and connecting the Bridge-AP (Fa0/14) to the switch in the wharehouse we got problems. The switch in the wharehouse reported host flappimg between ports in several VLANs. Also The clients on the APs in wharehouse and the wired clients started to lose connections to the services/applications in the main office.
The idea is that it works like this: ..... Under normal condistions the fiber is the primary "traffic-channel", in this case the two ports connecting the "Bridge-APs" at the two buidings are in "shutdown"! If the fiber breaks it will be disconnected at the core-switch and the two ports connecitn the "Bridge-APs" will manually be brought to "NO shutdown" to enable traffic to use the backup WLAN-link.
I attach a picture of the setup and the config of the two bridges and the config of the two ports connecting the bridge-APs and a snippet of the error log
QUESTION: What have I done wrong???.... I hope I have explained the problem and setup properly ....
