The Bridge Table of WIMAX-STN1 that is plugged into Fa0/5 is messed up.
There are some devices that it has listed being on interface WLAN0 (like the offending MAC address we have been speaking about) when they definitely are not. They are connected to Fa0/4 via the Hirchsmann switch at multiple locations kilometers away over the fiber.
The Bridge Table of the other WIMAX-#### devices all appear without errors...
Any thoughts?
