You can use the SCF INFO SUBNET command to determine if a SUBNET has been
configured for the TCPSAM process you plan to associate with the Expand-over-IP
line-handler process. Example 8-4 shows an example of an SCF INFO SUBNET
command for a process named $ZSAM1.
SUBNET names are shown in the Name field, the type of the SUBNET configured is
shown in the Type field, and the IP address assigned to the SUBNET is shown in the
IPADDRESS field. As shown in Example 8-2, there is one Ethernet SUBNET (SN1)
configured.
You must specify the IP address associated with an Ethernet SUBNET when you
define the Expand-over-IP line-handler process in Step 4: Create the Line-Handler
Process.
Creating an Ethernet SUBNET
If an Ethernet SUBNET does not already exist, you can create one using the SCF ADD
SUBNET command. The SCF ADD SUBNET command shown in the following
example defines an Ethernet SUBNET named SN1 for the Parallel TCP/IP
environment. The DEVICENAME modifier specifies the name of the logical interface
(LIF) that is used to communicate with the physical interface (PIF) on an E4SA
connected to the system.
-> ADD SUBNET $ZZTCP.*.SN1, TYPE ETHERNET, &
DEVICENAME $ZZLAN.LAN02, IPADDRESS 123.45.67.89,&
SUBNETMASK %HFFFFFF00
After the SUBNET is defined, it must be started using the SCF START SUBNET
command. The SCF START SUBNET command shown in the following example starts
the SUBNET named SN1:
-> START SUBNET $ZZTCP.*.SN1
For more information about creating SUBNETs, refer to the TCP/IP (Parallel Library)
Configuration and Management Manual.

Note. You must also perform this step on the destination system before you can define the
local Expand-over-IP line-handler process. The destination IP address must be specified when
the local Expand-over-IP line-handler process is defined.
