Define the characteristics of each LINK statement using BSDROUTINGPARMS
To define the link characteristics, such as MTU (1) and Subnet Mask (2), we used the
BSDROUTINGPARMS statement. If not supplied, defaults will be supplied from static routing
definitions in BEGINROUTES, OMPROUTE configuration (if OMPROUTE is running), or if
none supplied, the stack's interface layer based on hardware capabilities and characteristics
of devices and links. We defined our links with the highest MTU size, as shown in
Example 4-6.

4.4.2 HiperSockets implementation
The steps to implement HiperSockets are basically the same as we did to implement the
OSA-Express devices. What changes is that there is no external configurations to be done,
and the TRLE is created dynamically by VTAM.
When defining an MPCIPA HiperSockets, use the DEVICE statement to specify the IQD
CHPID hexadecimal value. The reserved device name prefix IUTIQDxx must be specified.
The suffix xx indicates the hexadecimal value of the corresponding IQD CHPID that was
configured with HCD or IOCP. Figure 4-9 on page 118 shows the HiperSockets
implementation scenario.

Create a DEVICE and LINK statements for each HiperSockets CHPID
Define the device and link statements for each HiperSockets CHPID being implemented, as
shown in Example 4-7. A HiperSockets CHPID must be defined as an MPCIPA type of device
1.
The link definition describes the type of transport being used. A HiperSockets link is defined
as IPAQIDIO 2.

Create a HOME address to each defined LINK
Each link configured must have its own IP address. Our HiperSockets links are defined with
the IP addresses, as shown in Example 4-8 on page 127.
