I am working on an access switch that has two gig ports configured as a single port channel going back to the core. In my mind, I would think that the implications of this set up would be the same as configuring VoIP packets to go accross a bonded T1 circuit without the benefit of interleaving. In my experience, if interleaving is not used on a bonded T1 circuit the audio quality suffers greatly as packets arrive out of order across the multiple circuits and are consequently dropped. Should this not happen with port channels as well?
With etherchannel, nothing guarantees that links will be used equally.
Seems like you put in doubt the ability of etherchannel designers to prevent out of order arrival.
