Any idea what goes wrong? Which configuration example would be right for InterVLAN router? Do you have any idea why left example would trash LACP link?
many thanks for thoughts.
Are the ports you are trying the LAG apart of a bridge span?
Why use arp-ip-target?
One general observation would be that LACP would break if apart of seperate Layer2 domain, so check for slave interfaces, bridges etc.
