DECNet over TCPIP behavior

Hi,

In tracking down a DECNet proxy problem I was surprised to find that DECNet connections were using TCPIP even though the name search path is LOCAL,DOMAIN. Running CDI_Cache_Dump confirmed this order.

We have always taken the default of NSP when registering names locally, but if TP4 is specified TCPIP is not used.

From this I assume that address selection, when multiple addreses are available, is to use OSI first (TP4 or TCPIP) and then NSP? The documentation mentions address selection but does not give specifics.

Is there a way to give NSP precedence over TCPIP? I'm concerned about reregistering nodes and people forgetting to NOT take the defaults.

Re: DECNet over TCPIP behavior

What are you entering as your host name for the connection? What's specified in the node name or host name field for the DECnet operation?

Randy,

You can say:

MCR NCL SET SESSION CONTROL TRANSPORT PRECEDENCE { NSP , OSI }

to favour NSP over OSI.

HTH,
