If you connect the MicroVAX ethernet port to a Cisco switch port, check that the Cisco switch port has spanning tree _disabled_
MOP booting and other low level protocols don't cope well with the spanning tree listening period the switch will enforce when the link is reset.

That's hard to believe.

Yeah. Swapping cards out fixed it anyway.   MOYA is now semi functional.


Certainly MOP should deal just fine, unless someone implemented it very badly.   Ditto any other DEC protocol.   After all, DEC invented the spanning tree algorithm, so handling its implications was just elementary network algorithm design for all of us.
