Cisco Systems 11.0 BT manual Defaults, When a specific LU name request is needed. The format can

pu (direct)

lu-seedlu-name-stem	(Optional) Provides an LU name that the client can use
	when a specific LU name request is needed. The format can
	be x...x## or x...x### where x..x is an alphanumeric string.
	When ## is specified, it is replaced with the LU
	LOCADDR in hexadecimal digits to form the complete LU
	name. When ### is specified, decimal digits are used,
	padded with leading zeroes to make three characters. The
	first x must be alphabetic and the entire string, including
	the # symbols, must not exceed 8 characters.
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, the pu pu-namecommand with no arguments puts you in PU configuration mode, where you can modify an existing PU entity.

The pu (direct) command uses values that are defined in two other commands: the lan internal LAN configuration command and the adapter internal LAN configuration command. The lan type and adapter adapter-numbervalues configured on the CIP internal LAN interface are used in the pu command.

For a link via a channel on this CIP, the TN3270 server and the hosts should open different adapters in the same internal LAN. Using different adapters avoids any contention for SAP numbers, and is also necessary if you configure duplicate MAC addresses for fallback CSNA access to the host. By configuring the 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
