Has anyone had any issues with the integrated NICs on the R900 management card not working properly with LACP in vSphere 5.5u2? I have two 6800s using add-in cards on my Extreme Summit 400 stack that seem to work just fine (other than ping amplification), but whenever I plug in more than one interface on the R900s, I lose connectivity to the R900. All ports in the group work individually, none work together. These are new to me R900s. I made an update CD yesterday with DRM, so the firmware should be current. The switch is configured exactly the same for those ports, verified with a config dump. Going back and forth from the R900s to the 6800s in vCenter the vSwitch appears to be configured the same. I'm not sure what else to try at this point.
