Is is possible to setup two incoming fiber links from a 6509 to a 3750. The goal is to setup a redundant fiber link should 1 gbic go bad (example). Is what I am describing GB ether channeling? Seems like this would create a spanning tree loop and yet it seems this should be possible. Any thoughts appreciated!
You could create an etherchannel which "bonds" them together creating a 2 gig channel. If a link fails, the channel stays up because it still has one good link left. From a spanning tree perspective, it's a single link. You can also run to separate fiber cables and have spanning tree block one of them, preventing a loop. If the active one fails, the other will become active and forward traffic. In the second scenario there could be a small outage as STP converges.
