Introduction

This document provides sample configurations for the Channel Interface Processor (CIP) card in IP Datagram and Offload mode.

Note: While Offload is still supported in the CIP, IBM has discontinued support for Offload in all version of OS/390 and subsequent mainframe operating systems.

Prerequisites

Requirements

There are no specific requirements for this document.

Components Used

This document is not restricted to specific software and hardware versions.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Conventions
