I'm using cisco ws-x6704-10ge blades in 3 6509 switches running sup-720's.
I have a query regarding etherchannel.
1) we have an existing 2 gig etherchannel link between the 3 switches. This existing etherchannel I would like to use as a backup to the new 10 gig etherchannel. Is there any config i need to do to the existing etherchannel to enable the 10 gig link to be used first instead of the 2 gig?
2) are there any restrictions in using 2 backbone etherchanels on the same switches?
3) If you have 2 Layer 2 etherchannels on the same switch 1 x 2gig backbone and 1 x 10gig (as a backbone to another switch) Which Etherchannel does the switch use to send traffic accross?
Thanks in advance
