Use this command to enable high-performance routing (HPR) support, disable
HPR support, or display the status of HPR support in the TPF system.
Requirements and Restrictions
- The TPF system must have completed Systems Network Architecture (SNA)
restart.
- The TPF system must be running in Advanced Peer-to-Peer Networking (APPN)
mode to enable HPR support. Enter ZNAPN APPN to place the
TPF system in APPN mode.
- When you enable HPR support for the TPF complex, it is enabled only on the
processors that have the rapid transport protocol control block (RTPCB) table
and high-performance routing session address table (HPRSAT) defined.
Format
- Status
- displays the current status of HPR support for the TPF complex and for the
processor on which the command was entered.
- Disable
- disables HPR support. The TPF system will run with base APPN
support.
- Enable
- enables HPR support in the TPF system.
Additional Information
- Online help information is available for this command. To display
the help information, enter one of the following:
ZNRTP HELP
ZNRTP ?
- When the TPF system is first generated, HPR support is disabled.
You must enter ZNRTP HPR ENABLE to start using HPR support.
- When you change the status of HPR support, the change is made on every TPF
processor in the loosely coupled complex.
- If adjacent link station (ALS) links are already active when HPR support
is enabled or disabled, the links must be deactivated and then activated again
to reflect the change.
Examples
HPR support is enabled in the TPF system in the following example.
+--------------------------------------------------------------------------------+
|User: ZNRTP HPR ENABLE |

|System: NRTP0005I 14.39.45 HPR SUPPORT IS NOW ENABLED |
+--------------------------------------------------------------------------------+
The status of HPR support in the TPF system is displayed in the following
example.
+--------------------------------------------------------------------------------+
|User: ZNRTP HPR |

|System: NRTP0007I 13.34.49 HPR SUPPORT IS ENABLED FOR THE COMPLEX |
| HPR SUPPORT IS ENABLED FOR THIS PROCESSOR |
