Heh, well, there's certainly very little understanding on my part. I don't administer the VMS end. However, I am friendly with the VMS sys admin, so it is more likely I'll be able to make changes at the VMS end than at any of the switches.

I managed to get the attention of the net admin here responsible for the switches and he assures me there is no filtering in place. > Phase V in Phase IV compatible addressing mode (which is what most people > use) will do all the Phase IV hello stuff and use Phase IV MAC addressing > for the ethernet packets. Now that's interesting. You say "... which is what most people use". But how do I (as an unprivileged user on the VMS host) determine if that is in fact what is used on this node? Could it be relevant that the MAC addr involved in all non-IP packets I was able to log from the VMS host is 08:00:2B:86:56:E1? That doesn't look like a area.node format MAC address. Does that mean this host just isn't in Phase IV compatible addressing mode? If not, what is the impact of switching it (i.e. could I get my VMS sys admin to change it without breaking anything else?)
