Following are some considerations for configuring TCP/IP for MVS:
for MVS
•
To specify a TCP/IP address space name other than the
default, TCPIP, code the following EXEC statement in the
appropriate PSF writer procedure:
STEP01 EXEC PGM=APSPPIEP,
PARM=(,,,,tcpip_name), REGION=4096K
where tcp/ip_name is the name of the TCP/IP address space.
If this parameter is not coded, PSF uses the default name,
TCPIP. (For a full description of the PARM parameter, refer to
Print Services Facility/MVS: Diagnosis Guide and Reference.)

Specify at least 160
buffers.
49152 Specify a buffer
size of at least

Specify at least 256
tiny data buffers.
See Notes.
Max packet size
parameter should
be no greater than
4472 bytes in a 4
Mbps LAN
configuration, and
17800 in a 16 Mbps
LAN configuration.
Default MTU value
in IPS printer is
2052.
