I've figured this out. Purely overlooking on my part. While I set the Vlans in question to tagged under the Lag while it was in general mode, when changing it to trunk it reverted them to forbidden in the trunk. I consoled into the switch and went through the config one by one and discovered this. Setting them back to tagged resolved the issue.
N4064 is the core switch with all VLANs. Core switch has a LAG set to trunk to N2000 switch and the lag is a member of all VLANs. The ports the core are attached to on the N2000 are a LAG set to general. For reasons beyond me, if I change the LAG on the N2000 series to trunk, I loose all management access to the switch. No CLI or Web UI. Interface is not pingable. All other traffic appears to be flow as normal. The LAG is a member of all VLANs on the N2000. Any suggestions?
