DISPLAY NETSRVR command

Abbreviations

Operand	Abbreviation
DISPLAY	D
SCOPE=ALL	EVERY or E
SCOPE=ONLY	NONE or N

When using an abbreviation in place of an operand, code the abbreviation exactly as shown in the table. For example, when coding the abbreviation for SCOPE=ALL, code only EVERY or E. Do not code SCOPE=E.

Purpose

The DISPLAY NETSRVR (network node server) command displays information about network node servers. Enter this command at the end node whose server information you want to display. This command is valid only when it is issued at an end node or migration data host.

Operands

SCOPE

Specifies the required scope of the display.

SCOPE=ONLY: Displays the network node server list that is currently active and displays the current network node server.
SCOPE=ALL: Displays, in addition to the information shown for SCOPE=ONLY, other network nodes known to the end node that can act as network node servers. Other network nodes are allowed as servers only if the current network node server list contains a nameless entry.

Resulting display

The resulting display shows:

The contents of the active network node server list.
For each network node in the list, an indication of whether support for SLU-initiated sessions is required or optional in order to establish a CP-CP session with this end node.
If the list contains explicit entries, the order in which the entries are used (FIRST or NEXT).
If SCOPE=ALL is specified, other network nodes known to this end node that are allowed as network node servers. Other network nodes are allowed as servers only if the current list contains a nameless entry.
The name of the current network node server. The name displayed here is the name of an adjacent network node that this end node has most recently determined to be a suitable network node server and with which this end node has either established CP-CP sessions or is in the process of establishing CP-CP sessions. At the time the DISPLAY NETSRVR command displays this name, CP-CP sessions with this network node may or may not be fully active yet.
The name of the preferred network node server if one has been specified.

For more information about how to code a network node server list, see the z/OS Communications Server: SNA Resource Definition Reference.
