Conﬁguring DTCs Step-by-Step

Modify the Network Management Conﬁguration File

Use the format nodename.domain.organization, where nodename

identiﬁes the DTC. If there is more than one DTC on the network,

the nodename of each DTC must be unique. The following are

examples of valid DTC node names on the same network:

ALPHA.ACCTG.TEKLAB

BETA.ACCTG.TEKLAB

Note that “DTC name” and “DTC node name” are two different

ﬁelds. However, it is acceptable (and common) to use the nodename

part of the “DTC node name” as the “DTC name”, such as:

DTC name = ALPHA

DTC node name = ALPHA.ACCTG.TEKLAB

4. (Optional) Enter an IP address for the DTC, if you want this DTC to

be able to respond to PING/iX requests. Otherwise, leave the “DTC

IP Address” ﬁeld blank.

For DTC 16RX access to an HP 3000 in an MPE/iX host-based

management environment, the IP address of the DTC 16RX is

conﬁgured using the DTC 16RX Manager on the HP 9000 host and

not on the HP 3000. Any value entered for the DTC 16RX in this

ﬁeld will be ignored.

Refer to Chapter 2, “Introductory Screens,” for more information on

IP addresses.

5. Enable the event logging classes that you want. It is recommended

that you enable classes 2 and 3 and disable classes 4 through 6. See

“DTC Event Logging” in Chapter 2, “Introductory Screens,” for

information on these event logging classes.

Note that logging class 1 is not conﬁgurable and is always enabled.

Event logging classes do not apply for access to an HP 3000 in an

MPE/iX host-based management environment using a DTC 16RX;

any values entered in these ﬁelds for the DTC 16RX will be ignored.

6. Verify that the cursor is in the “Type” ﬁeld under “Enter card

types as installed in the DTC.” Enter the card type for each

card in the DTC. The valid card types are listed on the screen.

Note that DTC 16iX/16MX/16RX does not have cards since its port

connectors are built directly onto the DTC backplane.

Refer to Chapter 2, “Introductory Screens,” for more information on

card types for each DTC.

7. (Optional) Enter a password if you wish to require the users to

provide a password when they attempt to establish a communication

link to this DTC via a PAD device. The syntax that the user would

use is described in PAD Proﬁles and Access Password in Chapter 4,

“Terminal and Printer Proﬁles,”
