You can activate a network node server list at startup by specifying the appropriate VTAMLST member name in your configuration list, or by using the VARY ACT command at an end node. If you use the VARY ACT command to activate the network node server list after a CP-CP session has already been established, the list is not used until the existing CP-CP session between the end node and its current network node server is lost or terminated. Use the VARY TERM command at the end node to deactivate the CP-CP session between the end node and the network node acting as the end node server. VTAM® will then use the network node server list in selecting a new server for the end node.

You can also dynamically replace an existing network node server list. To do this, create a new list and, as described above, use the VARY ACT command to activate it and the VARY TERM command to force VTAM to use the new list.

To display server information for end nodes, use the DISPLAY NETSRVR command at an end node to display the end node network node server list, the end node current network node server, and other network nodes known to the end node.
