When I add a second port to a existing LAG it is immediately disabled, why?

Question

Link aggregation issue

Everything appears to be correctly configured for some reason upon addition of the secondary port to the LAG it disables. I have tried everything short of completely eliminating the lag and reconfiguration but would like to avoid that if at all possible.

Not sure if I can help.....however it might help if you identify the Product\model type you are referring to.......the version of code\OS that you are running on the platform and device is on the other end of that LAG.

Hi Michael,Well, Not sure it detects a potential loop, Do u see any error message when lag is disabled ? ThanksJijo

Hi MichaelThere were changes to LAG operation in release 8.0.61 which may be causing issues as you have 8.0.30 on one node and 8.0.70 on the other. I would recommend upgrading the 8.0.30 node to match the other switch and make sure you have dynamic LAGs configured. Or migrate them both the 8.0.90d.
