Display Rapid Transport Protocol Pipes

The NCS : RTP Pipe List displays a list of Rapid Transport Protocol (RTP) Pipes, which are PU Type 2.1 nodes used by APPN High Performance Routing (HPR).

Note: If you want to display a summary of CP connections, use the CP option.

To display a list of RTP pipes

1. Enter /APPNRTP at the command prompt or enter RTP at the NCS : APPN Menu.

   The NCS : RTP Pipe List appears.

   The display has multiple pages, which you can access by scrolling right. The lines on this panel are color-coded, depending on the values of connection state, congestion, and queue for each pipe.

   Note: For information about the fields provided and actions available on the NCS : RTP Pipe List, press F1 (Help).

2. Perform any of the following actions to help you diagnose the pipes:
   • Use the SORT command to sort the list, for example:
     • SORT ACTUAL D sorts pipes by activity starting with the busiest.
     • SORT STALL D sorts pipes with those in a stalled condition first.
     • SORT CONGEST D sorts pipes with those with congestion first.
   • Press F10 (Left) and F11 (Right) to scroll through the pages.
   • Apply actions to find out more about the pipes, for example:
     • You can use the S action for a formatted display of the RTP pipe.
     • If the RTP pipe is using a suboptimal path, you can use the PSW action to force a pathswitch.

Display Transport Resource List Entries

Transport Resource List entries (TRLEs) define the characteristics of host-to-host channel connections.

To display a list of Transport Resource List Entries (TRLEs)

1. Enter /APPNTRL at the command prompt, or enter TRL at the NCS : APPN Menu.

   The NCS : Transport Resource List appears. The Status field is highlighted if the desired state does not match the actual state. The display has multiple pages, which you can access by scrolling right. For example, when you scroll right, you can identify any OSA priorities that have become congested because of excessive queueing.

   Note: For information about the fields provided and actions available on the NCS : Transport Resource List, press F1 (Help).

Display Dependent LU Requestor Resources

This option displays a list of dependent LU requestors for which this host acts as dependent LU server (DLUS). The DLUS sends data on a contention-winner session and receives data on a contention-loser session.

   Note: For information about the fields provided and actions available on the NCS : DLUR Resource List, press F1 (Help).

Display CP-CP Sessions

The CP-CP Session List displays a summary of CP connections.

From the CP-CP Session List, you can do the following:

• View the RTP Pipes for an adjacent CP
• Display connections for an adjacent CP
• Display the native VTAM display using Command Entry

To display the CP-CP Session List

1. Enter /APPNCP at the command prompt.

   The NCS : CP-CP Session List Appears.

   Note: For more information about the fields and options provided on this panel, press F1 (Help).

Test APPN Connectivity

The APPN APING function tests the route to another APPN node and displays performance information for the route. The results are displayed in the following sections:

Parameters (top)

Lets you change these parameters to perform a fresh APING for a node.

Results (middle)

Contains a series of lines, each showing the result of one APING operation. The latest result is shown at the top of the list.

Messages (bottom)

Displays messages relating to the latest APING operation.

Note: The APPN node must support the APING transaction.

To perform an APING on a node

1. Enter /SNAAPPN at the command prompt.

   The NCS : APPN Menu appears.

2. Type P at the command prompt and enter the following field:

   Node/CP Name

   Specifies the name of the resource on which you want to perform the action.

3. Press Enter.

   The NCS : APING Results List panel appears. For more information about the NCS : APING Results List panel, press F1 (Help).

   Note: To perform further APING actions, you can change any of the input parameters on this panel and press F6 (Action).

Display APPN Directory Information

The NCS : APPN Directory Entry panel displays information from the directory database about a particular resource and also about the resources that it serves and owns. For example, you can display a network node along with the end nodes that it serves and the LUs that it owns.

To display APPN directory information for a node

1. Enter /SNAAPPN at the command prompt.

   The NCS : APPN Menu appears.

2. Type AD at the command prompt and complete the following field:

   Node/CP Name

   Specifies the name of the resource on which you want to perform the action.

3. Press Enter.

Display APPN Subnetwork Topology Information

The NCS : Subnetwork Topology display shows the currently selected node (the origin control point) and any operative or quiescent adjacent destination control points.

To access this information

1. Enter /APPNTOP at the command prompt.

   The NCS : Subnetwork Topology panel appears.

   The first line of the selection list on this panel shows the selected node, and the following lines list its adjacent nodes. The information displayed can vary, depending on the VTAM level of your system, and on the types of resources available in your network.

   You can select any node to display node attributes. You can select an adjacent node to display transmission group attributes or to display its adjacent nodes.

   Note: For information about the fields provided and actions available on this panel, press F1 (Help).

Display Topology Attributes for a Node

The APPN : Node Topology Attributes panel displays routing characteristics for a node.

1. Enter TG beside the required node (the destination control point of a connection) on the NCS : Subnetwork Topology panel.

   The Transmission Group panel appears.

   Note: For information about the fields provided on this panel, press F1 (Help).

Display Adjacent Nodes for a Network Node

The NCS : Subnetwork Topology panel provides information about the adjacent nodes for the selected network node.

To access this display

1. Enter AT beside the required node on the NCS : Subnetwork Topology panel.
