DNAME protocol inhibition

Just upgraded to OpenVMS 8.3 with TCPIP_ECO-V0501-154. Previously DNAME protocol was inhibited on certain devices with a command like "def/sys/exec ewb0 nul" during system startup, this no longer works and i have DNAME protocol active on all available N/W devices. Certain of these are reserved for application specific use. How can i return to having DNAME protocol only on devices i specify?
Thank you in advance for any help available.

Re: DNAME protocol inhibition

David,

from the DECnet-OSI V7.3-2 ECO 1 release notes:

The logical name DNS$ETHERNET_DEVICE can be used to provide a list of devices that DNS should NOT use. All devices must be in the form _xxy0:. The string can contain spaces and other text which is ignored by DNS. For example, the following command tells DNS not to use the _EIA0: and _FWA0: devices.

$ DEFINE/SYSTEM DNS$ETHERNET_DEVICE "Don't use _EIA0: and _FWA0: "


This also works for more recent versions of DECnet-Plus on OpenVMS.
