TN3270 Server Commands 33

pu (direct)

Defaults

No PU is deﬁned.

The default remote SAP address is 04 (hexadecimal).

Command Mode

TN3270 conﬁguration

Usage Guidelines

If the PU is already created, thepu pu-name command with no arguments puts you in PU

conﬁguration mode, where you can modify an existing PU entity.

Thepu (direct) command uses values that are deﬁned in two other commands: the lan internal LAN

conﬁguration command and theadapter internal LAN conﬁguration command. The lantype and

adapteradapter-number values conﬁgured on the CIP internal LAN interface are used in the pu

command.

Fora link via a channel on this CIP, the TN3270 server and the hosts should open different adapters

inthe same internalLAN. Using differentadapters avoids any contention for SAP numbers, and is

alsonecessary if you conﬁgure duplicate MAC addresses for fallback CSNA access to the host. By

conﬁguringthe adapters in the same internal LAN, you achieve the same performance—bypassing

the DLC stacks—as looping back on a single adapter.

Examples

The following commands conﬁgure the TN3270 server to be active, and has one PU, CAPPU1,

trying to connect in. An LU seed using hexadecimal digits is deﬁned.

tn3270-server

pu CAPPU1 05D18101 10.14.20.34 token-adapter 3 rmac 4000.0501.0001 lu-seed CAP01L##

The following example shows different adapter numbers conﬁgured on the same internal LAN to

avoid SAP contention. The host uses SAP 4 on token ring adapter 0:

lan tokenring 0

adapter 0 4000.0000.0001

adapter 1 4000.0000.0002

tn3270-server

pu PU1 05d00001 10.0.0.1 token-adapter 1 8 rmac 4000.0000.0001 rsap 4

lu-seedlu-name-stem (Optional) Provides an LU name that the client can use

whena speciﬁc LU name request is needed. The format can

be x...x## or x...x### wherex..x is an alphanumeric string.

When## is speciﬁed, it is replaced with the LU

LOCADDRin hexadecimal digits to form the complete LU

name. When### is speciﬁed, decimal digits are used,

padded with leading zeroes to make three characters. The

ﬁrstxmust be alphabetic and the entire string, including

the# symbols, must not exceed 8 characters.
