TN3270 Server Implementation 2-27

These commands can be speciﬁed in the TN3270 Server conﬁguration mode the DLUR/Direct PU conﬁguration

mode. The commands affect all the LUs under the PU based on the siftdown value.

The default value for the IP precedence screen and printer parameters is 0. If IP precedence is not conﬁgured, the

IP precedence ﬁeld is set to 0 for both screen and printer. The default value for the IP ToS screen is 0.

When Telnet negotiation is taking place, IP precedence and IP ToS values of 0 are used. These values are used

until the Bind takes place. If it is a type 2 Bind, the TN3270 client is assumed to be screen. Otherwise, it is

assumed to be printer. These deﬁnitions of screen and printer might not be consistent with implementations in

other conﬁgurations or products. The IP precedence and IP ToS values are used until the TN3270 session is

terminated.

The show command displays four distinct values for IP precedence and the IP ToS. The values correspond to the

screen and printer. The following example shows the IP precedence and IP ToS as displayed in the show extended

command.

Conﬁguring PU parameters is required when you conﬁgure PUs that do not use DLUR. To conﬁgure PU

parameters for the TN3270 Server, perform the following tasks (Table 2-8) beginning in TN3270 conﬁguration

mode:

Table 2-8 PU Conﬁguration Tasks

Enter PU conﬁguration mode and create or

delete PUs with direct host links.

pupu-name idblk-idnum ip-addresstype adapno

lsap [rmac rmac] [rsap rsap] [lu-seed

lu-name-stem]

(Optional) Assign a TCP port other than the

default of 23. This command is also available in

TN3270 conﬁguration mode.

tcp-port port-nbr

(Optional) Specify the idle time for server

disconnect. This command is also available in

TN3270 conﬁguration mode.

idle-time num-of-seconds

(Optional) Specify the maximum time allowed

between keepalive marks before the server

disconnects. This command is also available in

TN3270 conﬁguration mode.
