  DECnet reachability? (SHOW NETWORK) 
 The Question is:
 
After upgrading from DECnet Phase IV to DECnet/OSI I can't use the DCL
command  sh net.
How can I get the information about active nodes on the network now ?
I know that I can convert the ncp sh active nodes command to ncl command,
but is there a way to get the information in the same way as with the sh net
command.
         thank you.
 
 
 
 The Answer is:
 
  The reachable nodes information provided by SHOW NETWORK is only
  available from DECnet Phase IV routers, and is not available from
  non-routing nodes.
 
  As for DECnet-Plus, this information is not generally collected and
  maintained in OSI and IP network host systems, as it can quickly
  overwhelm a system.  Various census agents and related tools have
  been available to gather and maintain this information.
 
  There is no direct equivalent of NCP SHOW KNOWN NODES in NCL.  This
  task was trivial under DECnet Phase IV, as the node database was local
  to DECnet.  Now the information can be spread out through a variety of
  name servers.
 
  To find this information from your OSI router, you can try the
  following:
 
    to display the adjcent nodes on the particular routing circuit:
 
      NCL&gt; SHOW ROUTING CIRCUIT 'CIRCUIT NAME' ADJ * ALL STATUS
 
    to display all nodes that are reachable in the area:
 
      NCL&gt; SHOW ROUTING DEST NODE * ALL
 
    to display all reachable areas:
 
      NCL&gt; SHOW ROUTING DEST AREA ALL
 
  The syntax on the particular router -- if not NCL -- will vary.
 
  To look around within the DECnet-Plus DNS namespace and for the nodes
  that are in the local node's cache, please see the sys$system:dsmdecdns
  and decnet_register tools.   If you are "merely" looking to diagnose
  DECnet reachability, try the command sys$system:cdi$trace.
