Bill - just a quick check. Does it really matter that the MAC address
gets set? Do you have some other device that also sets the same MAC
address? Otherwise the MAC address don't really matter. It's just 48
bits that needs to be unique.

The system is running multinet, so accessing the system vi TCP/IP

Hi Bill,
You want VMS to not try and change the MAC address.

So, exactly how do you plan/want to access the simulated VAX?
What do you envision the network to look like?

The same debugging commands that enabled the above XQ debug
output can certainly be put in the vax configuration file.
I'm not sure how that will help anything.

"setup packet" and changing the SRC MAC address?
Something in VMS is changing the MAC address on the simulated
interface by issuing the appropriate I/O operations to do this.
It may be DECnet or it may also be other networking things on
the system.
Before we dig into the details of that, answering the above
questions about how you envision the network to look will be
more helpful.
