  Configure DECnet on Network Controller? 
 The Question is:
 
I have just installed a DE500 on an Alphastation 500/400 running OpenVMS v7.1-2.
 
The ethernet card is recognised by the system as EWB0.
 
$ sh dev ewb0/ful
 
Device EWB0:, device type DE500, is online, network device, device is a template
    only.
 
    Error count                    0    Operations completed                 0
    Owner process                 ""    Owner UIC                      [SYSTEM]
    Owner process ID        00000000    Dev Prot              S:RWPL,O:RWPL,G,W
    Reference count                0    Default buffer size                 512
 
 
However when I tried to disable DECNET on the on-board ethernet card (EWA0) and
 define line and circuit on EWB-0 using NCP, it give me the error:
 
NCP&gt; list known line
 
Known Line Permanent Summary as of  5-JUL-2001 16:33:39
 
   Line             State
 
  EWB-0             on
  EWB-1             on
 
NCP&gt; NCP&gt;set line ewb-0 state on
%NCP-W-INVIDE, Invalid identification format , Line
 
%SYSTEM-F-IVDEVNAM, invalid device name
 
I  tried reboot the system with the network connected to the new ethernet card
 (DE500). VMS cluster would use the new EWB0 connection for cluster formation
 with no problem but DECNET still failed to startup using EWB0.
 
Have I missed configure sonething?
 
We would like to use the network using the new card only and would not mind to
 remove EWA0 completely if possible...
 
Thanks for any help.
 
 
 The Answer is:
 
  Assuming this is a DECnet Phase IV system (as would be implied by
  your use of NCP), re-run NETCONFIG.COM.  If this is a DECnet-Plus
  system, re-run NET$CONFIGURE.COM.
 
  You cannot run DECnet Phase IV on multiple NICs, should multiple
  NICs be connected to the same non-bridged, non-switched, non-routed
  segment.  (If this configuration should arise, you will receive the
  IVADDR invalid media address error when DECnet starts on the second
  and again on any subsequent controllers connected to the segment.)
