Customization
Overview
The purpose of this section is to provide an overview of the procedures used to complete the customiza-
tion of the NESiGate Offload channel-to-IP NetEx/IP gateway for use with NetEx/IP offload products.
This section is targeted to the end-user responsible for customizing a NESiGate appliance for use as a
NetEx/IP offload channel device. It is assumed the NESiGate already has the appropriate level of the
system software installed. To complete the customization, the reader must be familiar with channel de-
vice and network addressing concepts.
The customization process consists of these major steps:
1.
Configure NESiGate
2.
Configure NetEx/IP
3.
Update DNS or local ‘hosts’ file (optional)
4.
Reboot NESiGate
Device addressing
Prior to performing the Device and IP customization tasks, it would be beneficial to review NESiGate
device and network addressing concepts.
There are three important addressing elements involved in delivering NetEx/IP channel data that is not
IP-aware, and transferring it over an IP network to the correct destination:
•
Device Number
•
GNA Address
•
IP Address
Device Number
The Device Number on the host and Device Index on the NESiGate channel board are numeric repre-
sentations of the same unique "device". On the Host operating system, a "Device Number" is mapped
as a Unit Address on a Logical Control Unit (a physical control unit may consist of from 1-16 logical
control units). The Physical Control Unit may be connected to a Port on an ESCON Director. Multiple
inbound Host channels may be connected to the ESCON Director and provide connectivity to the device
from multiple partitions (LPARs) across multiple hosts.
