Configuring Enterprise Extender communications for the iSeries system

Enterprise Extender is a networking architecture that allows Systems Network Architecture (SNA) applications to run over IP networks using High Performance Routing (HPR).

Enterprise Extender is the preferred way to run SNA applications over IP networks with communications input/output adapters (IOAs), such as Gigabit Ethernet, because these IOAs do not require an input/output processor (IOP). Communications adapters that do not use an IOP do not support SNA. Therefore, Enterprise Extender is required to run SNA over these adapters. It is recommends that Enterprise Extender be used in place of AnyNet®.

Setting up the Enterprise Extender environment

Note: Before you configure HPR to run over IP networks, you must enable HPR transport support by specifying ALWHPRTWR(*yes) on the CHGNETA command.

To configure HPR to run over IP networks, follow these steps:

  1. Configure your TCP/IP network.
  2. Create an APPC controller description and specify the link type *HPRIP.
