January 15, 1999
This document supplements the Cisco IOS Release 11.0 documentation set with new and changed
commands that support Cisco IOS Release 11.0(10)BT and later. Note that Cisco IOS Release
11.0(10)BT is the initial release of Cisco IOS Release 11.0 BT. No prior versions of Cisco IOS
Release 11.0 BT exist. The TN3270 server function is supported on a Channel Interface Proc

Configuring TN3270 on a Channel Interface Processor Note To enable the TN3270 server feature, you must have a CIP installed in a Cisco 7000 family router. The TN3270 server is different from the TN3270 terminal emulation access feature described in the “Configuring TN3270” chapter of the Access Services Configuration Guide. Configuring TN3270 on a Channel Interface Processor The following sections describe additional features of TN3270 server support on the CIP. The features discussed include the f

Configuring TN3270 on a Channel Interface Processor • IBM-DYNAMIC: This will result in “DYNAMIC” being put in the model type and number field. The VTAM configuration will need to have “DYNAMIC” defined as a template in the LU group. In fact “IBM-ZZ..Z,” where “ZZ..Z” does not match the preceding syntax, will be forwarded as “ZZ..Z.” Note The “E” in the model string refers to 3270 extended datastream. It has no connection with the “E” in “TN3270E”. • Any other string is forwarded as is. • In all ca

VTAM Host Configuration Considerations for Dynamic LU Allocation SNA Session Switch—End Node DLUR An end node DLUR function is implemented as part of the TN3270 server. The purpose of the DLUR is to allow the routing of TN3270 LUs to multiple VTAM hosts to be performed in the CIP card rather than on the VTAM hosts. The need for this feature will increase with the introduction of the new multi-CPU CMOS mainframe which comprises up to 16 CPUs that appear as separate VTAMs. The implementation of TN

TN3270 Configuration Modes After the VTAM activation, the server can support session requests from clients using dynamic or specific LU allocation. TN3270 Configuration Modes The TN3270 configuration modes and router command prompts are described in the following sections and displayed in Figure 3. The TN3270 server can be configured only on Port 2, the internal LAN port, of a CIP card. Some configuration commands create entities on the CIP. For most of these, the command changes to the mode associat

TN3270 Configuration Task List TN3270 Configuration Task List The following sections describe how to configure TN3270 server support on the CIP. Not all tasks are required. Refer to “TN3270 Configuration Example” for configuration examples. Note The TN3270 server is configured on an internal LAN interface in the CIP, which is port 2 of a CIP. Port 0 and port 1 represent physical interface ports; port 2 is a “virtual” port and is always reserved for the internal LAN interface. Task List for Multiple A
