14 Configuring TN3270 Server on the Channel Interface Processor
TN3270 Configuration Task List
Configure TN3270 Server
Thistask is required. To establish a TN3270 server on the internal LAN interface on the CIP,perform
the following tasks beginning in global configuration mode:
Whenyou use the tn3270-server command, you enter TN3270 configuration mode and can use all
other commands in the task list. You can later override many configuration values you enter in
TN3270 configuration mode from PU configuration mode. On IBM host systems, these types of
commandsare often referred to as “sift down” commands because their values can sift down through
several levels of configuration and can be optionally altered at each configuration level.
Configure PU Parameters on the TN3270 Server
This task is required when configuring PUs that do not use the SNA Session Switch feature. To
configurePU parameters for the TN3270 server, perform the following tasks beginning in TN3270
configuration mode.
Task Command
Select the channel attach internal LAN interface
and enter interface configuration mode. interface channelslot/2
Specify a TN3270 server on the internal LAN
interface and enter TN3270 configuration mode. tn3270-server
(Optional) Configure maximum number of LUs
allowed. maximum-lusmax-number-of-lu-allocated
(Optional) Configure transmission of a WILL
TIMING-MARK. timing-mark
(Optional)Assign a TCP port other than the default
of 23. This command is also available in PU
configuration mode.
tcp-portport-nbr
(Optional) Specify the idle time for server
disconnect. This command is also available in PU
configuration mode.
idle-timenum-of-seconds
(Optional) Specify the maximum time allowed
between keepalive marks before the server
disconnects. This command is also available in PU
configuration mode.
keepalive num-of-seconds
(Optional) Specify whether the TN3270 session
will disconnect when an UNBIND command is
received. This command is also available in PU
configuration mode.
unbind-action {keep |disconnect}
(Optional) Select whether “left-over” LUs can be
usedfrom a generic LU pool. This command is also
available in PU configuration mode.
generic-pool {permit |deny}
Task Command
Enter PU configuration mode and create or delete
PUs with direct host links. pupu-name idblk-idnum ip-address type adapno

(Optional)Assign a TCP port other than the default
of 23. This command is also available in TN3270
configuration mode.
