VSWITCH

Very much WIP, not formatted, will work on presentation later

Config Changes

System Config

Define VSWITCH and grant our TCPIP service VM to it.

We're going to attach this VSWITCH to RDEV 0400 which was previously used by TCPIP.

### TCPIP DIRECT entry


PROFILE TCPIP:

``` text

must be changed to

DIRM FOR TCPIP REPLACE

TCPIP Config

The changes above mean that TCPIP VM can still access a "NIC" at 0400, we only need to make one small change to SYSTEM DTCPARMS:

TCPMAINT 198: SYSTEM DTCPARMS

Comment out :attach statement

.*             :attach.0400 AS 0001,0401 AS 0002,0402 AS 0003

Re-IPL

At this point we should have made all the necessary changes to the TCPIP config.

When we re-IPL our system, we should have:

A VSWITCH named VSWITCH1 bound to our OSA at real device 0400
A TCPIP VM user definition with a virtual nic at virtual device 0400 and placed on VSWITCH1
