Primary and Secondary aggregator

[prado2010]

Hi Friends,

I found a term called primary aggregator and secondary aggregator in etherchannel with the "show etherchannel portchannel command" on 3550 MLS so, could someone try describing this plz..

Thank you

Could you provide the output plz as i did find the following info...

A secondary aggregator port will be created in the LACP process when the ports you are bundling are not compatible with each other, or with their remote peers. The secondary aggregator port will have the ports which are compatible with others.

This would suggest all your ports are not utilising the channel correctly.

Is it the same on both ends of the channel?
