Decnet OSI

Hi,

sorry if my question isn't very clear, in order to suppress decnet on our network, i want to know how decnet choose between osi transport and nsp transport protocol?
what kind of problem can we meet and what will be done to avoid them?
Is there something to configure?

We have:
vms V6.2
decnet/osi v6.3
ucx v4.2

thanks in advance for you help

Steph.

You can disable nsp and/or osi transport (make the .ncl empty or use net$configure.

If one of the nodes of a communication doesn't support osi, nsp will be used. Idem if the routers in between don't support osi.
Idem if the node is not setup with the right osi addresses in decnet_register.

Best is to check the usage with :
$ mc ncl show osi tra all
$ mc ncl show nsp all
(check currently active)

are you using DECnet over IP?
Ensuring DECnet name resolution finds an IP name first also helps.

Hi Ian,

yes we use decnet over ip with the pwip driver

i am a newbie in decnet, i think there is a link between decnet name resolution and the selection of the transport protocol, i am right?
if yes, someone could explain me the relationship and what i have to do to be sure that we use every time decnet over ip and not nsp?
