we have a problem with a asymetric load-balancing in a LACP link. We have a switch-down (2970) with a LACP link formed by ports 16, 17, 6 and 7. In the switch-up the same LACP link is formed by 16, 17, 18 and 19. The ports are wired:
sw-down GE0/16<->sw-up GE0/16,
sw-down GE0/17<->sw-up GE0/17,
sw-down GE0/6<->sw-up GE0/18,
sw-down GE0/7<->sw-up GE0/19,
The issue is that traffic that going to switch-down port 6, go back through switch-up port 19, instead port 18. This is a problem because in each link there is a linux machine that filter the web traffic (pornographics access, etc...). Now the machines in links 6-18 and 7-19 have problems because asymetric traffic.
Are there any way to force a match between Ports by configuration?.
