122 Communications Server for z/OS V1R7 TCP/IP Implementation, Volume 1 - Base Functions, Connectivity, and Routing
Example 4-1 depicts some of the IOCP statements we used in our test environment
(OSA-Express CHPID 02 and HiperSockets CHPID F4). These statements are required by
the input/output subsystem and the operating system. Since all our OSA-Express and
HiperSockets connectivity will be used across all three LPARs, we defined the CHPIDs as
shared.

4.4.1 OSA-Express implementation with VLAN ID
To implement OSA-Express (QDIO) in our test environment we followed these tasks:
1. Verify the switch port configuration.
2. Define a TRLE in VTAM to represent each OSA-Express port.
In the TCP/IP profile:
1. Create DEVICE and LINK statements for each OSA-Express port.
2. Create a HOME address to each defined LINK.
3. Create a direct route statement for each LINK.
Figure 4-12 on page 123 shows the OSA-Express implementation scenario.
