Thanks for the help. I may have got this working but I'm uncertain if some of my configuration choices were correct because some of them are only available under the global context and not individual interfaces. The specific ones from my configuration were: time_stamping step_threshold gmCapable priority1 priority2 assume_two_step
I'm not sure how setting some of these for the 1588v2 configuration would impact things because most were for the gPTP case. Also, should boundary_clock_jbod be configured in global, for each interface, or only specific ones (i.e. the clients)?
