Hi Folks, I have a design in which Cisco 3548 XL's are GBIC-stacked on various floors of a campus and are uplinked to a core Cat 6509 switch. The uplink from every floor stack is ether-channeled to the core via two parallel equal-cost paths. One uplink path starts "forwarding" and the other goes into "blocking" mode from each floor stack.
Here is my confusion... If only one link of a 400 MBps full-duplex ether-channel fails from the forwarding path , will it invoke spanning-tree recalculation ??? Or will the 'now' sub-optimal path still remain in forwarding mode and the now more-bandwidth path remain in blocking mode ??? Since spanning-tree recalculation causes a lot of ripples throughout the switched network, I would assume that the latter were true. However, I would like to hear views from people who would think that the former scenario is more probable. Thanks very much.
