We have a 4507 switch with redundant supII-plus-10GE with 10Gbase-LR gbics and we are connected via single mode fiber to a 6509 with redundant SUP32-10GE with 10gb-LR gbics. The two active supervisors are connected at 10 gb, I would like to add a 10 gb connection to the redundant supervisors using an etherchannel for added speed and failover. I used the following configs but the lines would go err-disabled. Any help would be greatly appreciated.
Thanks
