ZNAPN-Display or Change APPN Status

Use this command to display or change the current status of the Advanced Peer-to-Peer Networking (APPN) migration switch for the TPF system. The migration switch indicates whether the TPF system is using APPN support or low-entry networking (LEN) support.

You can also use this command to display the network topology for the TPF loosely coupled complex.

Requirements and Restrictions

You can enter the ZNAPN command only in 1052 state or higher.

Format




Status
displays the current setting of the migration switch.

APPN
sets the migration switch to APPN support.

LEN
sets the migration switch to LEN support.

TOPology
displays information about the active PU 2.1 links connected to the TPF loosely coupled complex.

CPU-x
displays the network topology for a specific processor in the loosely coupled complex, where x is the CPU ID of that processor.

CP-netid.cpname
displays the active links to a specific remote control point (CP), where netid.cpname is the 1- to 17-character name of that CP.  The network ID and name of a resource must both begin with a letter (A-Z), @, #, or $. The remaining characters can be letters (A-Z), numbers (0-9), @, #, or $. 
Note:
 To specify an SNA network ID or resource name that contains dollar signs ($), you must type two consecutive dollar signs ($$) for each dollar sign in the network ID or resource name. For example, if the SNA resource name is $SNANAME, you must type $$SNANAME

+--------------------------------------------------------------------------------+

The network topology is displayed in the following example, where:

 LINK 
is the name of the adjacent link station (ALS).

 CPU 
is the CPU ID of the loosely coupled processor to which the ALS is attached.

 NETID 
is the network ID of the remote CP name for the node that owns the ALS.

 CP NAME 
is the remote CP name for the node that owns the ALS.

 TG 
is the transmission group (TG) number assigned to the link.

 CP-CP 
indicates whether the link supports CP-CP sessions.

 QUIESCED 
indicates whether the link has quiesced.

 HPR 
indicates whether high-performance routing (HPR) support is supported on the link and, if so, whether the link connects to a rapid transport protocol (RTP) node or an automatic network routing (ANR) node.
