We have several sites that use Proxim's GigaLink 6451e wireless bridge to connect between their buildings.
For some odd reason, the switchport on our 3750G would take errors, even after we swap out every component between the devices. (fiber, SFP, and even tried a different switch)
We insisted that the problem is w/ the bridge, so Proxim took it back to their repair lab, and determined there's nothing wrong w/ it.
So we're now stuck.
Has anyone had this weird problem before?
Below is the show output from the switch, could someone tell me why we're taking errors?
