I have a configuration that involved 2 4900m's with one 2x10gig etherchannel moving traffic to another 4900m. this configuraiton also has a 4x10g etherchannel connecting to a 6509. The 2x10gig is the production, and part of the 4x10g is backup for the 2x10g. Since average traffic load will be 10-12gigs, I need the entire port-channel to drop if one link fails. I know I can do this on routing, but havent found a way in switching. Any ideas?
