I have a L2 portchannel between a 9407 and two Nexus 5000
We have Exfo testers at each end.
My port one on 9407 goes two port two on his nexus and I loop his port two.
He does the opposite. He port one loops my port two and we both send a 1Gig Down the link.
However I seem to be losing half a gig traffic either side.
I believe this is to do with the portchannel load balancing.
I've gone through all the load balancing options on the 9400 and it hasn't made any difference.
1. Do I need to set the same otions on the nexus?
2. Is it something else other than load balancing?
Can you post both the side configuration to have a look. what kind of spanning tree, where is the root bridge ?
Can you please share the actual connection diagram? I'm not sure I understand your layout correctly.
