ALIAS DLU.



Yes the IST664I indicated an ALIAS DLU:

 
                A default ADJCLUST table must be coded without NETID specified and the table
                must include this host's CPNAME in the table. VTAM will not even search it's own
                NETID without a default table that includes it's own CPNAME.
 
                Issue a D NET,ADJCLUST

                    This CPNAME should appear in the table as well as any Border Nodes that were
                    added to the table.
                   
                If a table is not found with this display then code a default ADJCLUST or use either
                BNDYN=FULL or BNDYN=LIMITED.               
              


                 When an ALIAS name is used for a session request VTAM will upgrade
                 BNDYN=LIMITED to BNDYN=FULL automatically.
                 Coding BNDYN=LIMITED will act the same as if you coded BNDYN=FULL.

                               

                For these options VTAM should dynamically add all active Border Nodes to the
                ADJCLUST table. No coding of tables are required.
                An active Border node is an adjacent Border Node that actually has a connection to
                another NETID.
