Configuring and Managing Host-Based X.25 Links - Edition 6 (36939-90057)

Introduction

Operation

Chapter 1

Operation

When the HP 3000 is configured to use host-based X.25 networking configurations, the

command DTCCNTRL is provided to allow operators to start and stop X.25

system-to-system or PAD connection support, obtain status about whether X.25 and PAD

support are up, and to dynamically change many configuration parameters entered for

the DTS subsystem without rebooting the system.

System Operator (OP) capability is required to obtain status and start and stop X.25 and

PAD support. Network Administrator (NM) is required to perform dynamic

configuration

Dynamic Configuration

You can make many DTS changes dynamically without rebooting the system, or

resetting and redownloading the DTC. This capability is available if you already have a

valid network configuration file, and there were no errors reported by DCC during the

last system reboot, or DTS shutdown and restart. This allows you to modify the DTS

configuration without impacting all the users accessing the system through the DTC

that was changed.

For more information on how to invoke dynamic configuration, see Chapter 7, “Managing

Networks with DTCCNTRL,” of this manual, or the Configuring Systems for Terminals,

Printers, and other Serial Devices manual.

Automatic Configuration

Host-based management also gives you the capability to add and configure a new DTC

automatically, without the need to specify most of the detailed configuration information,

such as DTC cards and ldevs. This can be done within the NMMGR utility or at the

session prompt with the command DTCCNTRL. Refer to Chapter 7, “Managing Networks

with DTCCNTRL,” for further information on using automatic configuration to configure

X.25 cards. See Configuring Systems for Terminals, Printers, and Other Serial Devices

manual for more information on how to invoke automatic configuration.

Obtaining Status

The DTCCNTRL Status function displays the current status of each DTC/X.25 Network

Access card installed in a specified DTC. Use the Status function to determine whether

or not X.25 or PAD support is currently active for a DTC/X.25 Network Access card. See

Chapter 7, “Managing Networks with DTCCNTRL,” for more information on obtaining

status using DTCCNTRL.
