Modify the Network Management Configuration File (Cont'd)
Step 11: Configure X.25 System-to-System Information
NMMGR displays the DTC X.25 Card Configuration- Sys-to-Sys LUGs screen
(see Figure 3-10 ) if you press the [Go To SysLUG] key at the DTC X.25
Card Configuration screen or the DTC X.25 Card Configuration - Level 3 &
Miscellaneous screen. On this screen, you specify information for X.25
system-to-system connections. You can also reach this screen by typing
the following path at the Command line and pressing the [ENTER] key:
@DTS.DTC.SELECT.dtcname.X25CARDn.SYSLUG
Figure 3-10. DTC X.25 Card Configuration - Sys-to-Sys LUGs
1. Verify that the cursor is in the X.25 link name field. Enter the
link name that will be used for X.25 iX System Access (X.25
system-to-system connections) for this DTC/X.25 Network Access
card. This link name must be the same as the link name configured
on the X.25 Configuration screen during NS configuration (see
chapter 6).
2. Move the cursor to the Maximum number of Switched Virtual Circuit
field. Enter the maximum number of SVC connections that will be
supported for this card.
3. Move the cursor to the System X.25 address field. Enter the same
X.25 address as entered in the X.25 card address field on the
Level 3 and Miscellaneous screen unless your network application
requires the address used for X.25 system-to-system communications
to be different from that used for PAD communications. If the
addresses must be different, enter the X.25 address that the local
system will use for system-to-system connections in this field.
Note that with certain networks (such as Transpac, in France) the
called address is removed from incoming call packets and the
calling address is added to outgoing call packets by the network.
For these networks, enter only the subaddress in this field, not
the full X.25 address.
4. Move the cursor to the first Address field under Enter remote X.25
addresses and security. Enter the X.25 address of a system that
will be able to establish a system-to-system connection with the
HP 3000 Series 900 you are configuring.
5. Move the cursor to the Sec. field next to the address you just
entered. Enter the security level for connections between the
remote X.25 address and the system you are configuring. Possible
values are IN (accept calls from the address), OU (send calls to
the address), and IO (accept calls from and send calls to the
address).
6. Repeat steps 4 and 5 for each remote system that will be able to
establish a system-to-system connection with the HP 3000 Series
900 you are configuring. If you need to enter more than eight
remote system addresses, press the [Save Data] key to save the
data on this screen, then use the [Next Page] key to move to a new
data entry screen to configure additional addresses.
7. When you have entered all remote X.25 addresses and associated
security, press the [Save Data] key to save the configuration.
8. Press the [Go To PAD] key to move to the DTC X.25 Card
Configuration - Nailed PAD Connections screen.
Fields
This screen lets you configure X.25 system-to-system local user
group(LUG) information for the DTC/X.25 Network Access card being
configured.
DTC name Display only.
Card number Display only.
X.25 link name The name of the link that will be used by
the system being configured for X.25
system-to-system connections. Must be the
same as the link name entered during NS
configuration of X.25 iX System Access using
the NS subbranch of NMMGR. The link name can
be up to eight alphanumeric characters,
beginning with a letter.
Maximum number of The number of switched virtual circuits
Switched Virtual (SVCs) that will be allowed through this
Circuits DTC/X.25 Network Access card. Up to 32 SVCs
are allowed for cards mounted in a DTC 16,
up to 256 SVCs are allowed for cards mounted
in a DTC 48 and up to 156 SVCs are allowed
for cards mounted in DTC 72MX.
The following factors must be considered in
determining how many SVCs to allow:
* The total number of SVCs which an
X.25 board can establish depends on
the packet size configured in the
X.25 level 3 configuration. Upper
limits for each DTC48 and DTC72MX
card are:
* 256 for packet sizes of 512 or
less.
* 150 for 1024 byte packets.
* 100 for 2048 byte packets.
* 54 for 4096 byte packets.
Note that these limits are not
affected by packet size
negotiation. That is, if you
have configured a packet size
of 4096, and a packet size of
128 has been negotiated, you
are still limited to the 54
SVCs supported with 4096 byte
packets.
* If you are also configuring PAD
connections on this card, remember
that PAD connections use SVCs out of
the pool of available SVCs. You will
need to balance your PAD support
requirements with your system-to-
system requirements to find the
optimum configuration for your
network.
* The total number of SVCs available
may also be limited by your PSN
subscription.
System X.25 address This is the X.25 address of the X.25 card,
to be used for system-to-system connections.
In most cases, this will be the same as the
address entered on the Level 3 &
Miscellaneous screen. If, however, your
network application requires the
address used for X.25 system-to-system
communications to be different from the
address used for PAD connections, enter a
different address here. For most
connections to public data networks, this
will be the DTC/X.25 Network Access card
address plus a unique subaddress for the
host system.
Note that with certain networks (such as
Transpac, in France) the called address is
removed from incoming call packets and the
calling address is added to outgoing call
packets by the network. For these networks,
enter only the subaddress in this field, not
the full X.25 address.
Address The X.25 addresses of the remote systems in
your X.25 network
Sec. The security level associated with each
remote X.25 address. To accept only
incoming calls for call setup, enter IN in
the security field beside the address. To
allow only outgoing calls for call setup,
enter OU. To allow both incoming and
outgoing calls for call setup, enter IO.
Step 12: Configure Nailed PAD Connections
NMMGR displays the DTC X.25 Card Configuration- Nailed PAD Connections
screen (see Figure 3-11 ) if you press the [Go To PAD] key from the
DTC X.25 Card Configuration screen or the DTC X.25 Card Configuration -
Sys-to-Sys LUGs screen. On this screen, logical device (ldev) numbers,
profile names, device names, and remote X.25 addresses are permanently
associated with individual PAD connections allowed through the card.
Configure the connections as required. You can also reach this screen by
typing the following path at the Command line and pressing the [ENTER]
key:
Table 3-6.

nailed connection.
5. If you want to associate a closed user group number with this
nailed connection, move the cursor to the CUG No. field and enter
the CUG number.
6. Repeat the above steps for every device attached to this card.
(You can use the [Fill Cards] key to fill in ldev and profile
information.) If you need to configure more than eight nailed PAD
connections for this card, press the [Save Data] key to save the
data on this screen, then use the [Next Page] key to move to a new
data entry screen to configure additional nailed connections. You
can configure up to 256 nailed PAD connections for each card.
7. When all nailed connections have been configured, press the [Save
Data] key.
8. Press the [Go To Security] key to move to the DTC X.25 Card
Configuration - PAD Security screen.
Fields
This screen is used to permanently associate ldev numbers and other
information with individual connections that can be made through a
DTC/X.25 Network Access card; that is, to configure nailed PAD
connections.
DTC name Display only.
Card number Display only.
Ldev The logical device (ldev) number to be associated
with the connection. Each ldev number must be
unique; it may not be duplicated by any other
device configured on the system.
Profile The PAD terminal or PAD printer profile name to be
associated with the connection. The features
defined by the profile must correspond to the
actual operating features of the connection and the
device.
Device Name The name associated with the PAD-connected terminal
or printer. The device name can be up to eight (8)
characters and must be unique for each PAD
connection.
Remote Device (PAD) The X.25 address of the remote PAD device. Where
X.25 Address devices are connected to a multiport PAD, include
port subaddresses in this field.
CUG No. (Optional) The closed user group number(0 to 99), if specified
for your network subscription. Leave blank if your
subscription does not specify a CUG number.
Step 13: Configure PAD Security
NMMGR displays the DTC X.25 Card Configuration - PAD Security screen (see
Figure 3-12 )if you press the [Go To Security] key from the DTC X.25
Card Configuration screen or the DTC X.25 Card Configuration - Nailed PAD
Connections screen. On this screen, you specify either a list of PAD
calling addresses that will be accepted or a list of PAD calling
addresses that will be rejected for connection through the DTC/X.25
Network Access card being configured. You can also reach this screen by
typing the following path at the Command line and pressing the [ENTER]
key:
@DTS.DTC.SELECT.dtcname.X25CARDn.PADSEC
Figure 3-12. DTC X.25 Card Configuration - PAD Security
1. Verify that the cursor is in the Allow access field. If you want
to accept calls only from the calling addresses listed below (and
reject all other calls), enter a Y. If you want to reject calls
only from the calling addresses listed below (and accept all other
calls), enter an N.
2. In the fields under Enter remote X.25 calling address below:,
enter the X.25 addresses of all remote PAD devices that will be
accepted for connection, if Allow access is Y, or enter the
addresses of all remote PAD devices that will be rejected for
connection, if Allow access is N. If you need to configure more
addresses than there is room for on this screen, press the [Save
Data] key, then press the [Next Page] key to enter more device
addresses. Up to 512 remote X.25 calling addresses can be
configured.
3. If you have finished configuring PAD security for this card but
still need to configure additional cards or DTCs, press the [Prior
Screen] key until you return to the DTC Configuration screen so
that you can select a different card or DTC to configure.
4. If all DTCs and all cards have been configured, press the
[Validate DTS/LINK] key to validate the DTC configuration for the
system. (See appendix A for validation error messages.)
Fields
DTC name Display only.
Card number Display only.
Allow access Specifies whether connection requests from
devices whose addresses are listed will be
accepted (Y) or rejected (N).
If you enter Y, calls will only be accepted
from devices whose addresses you list on
this screen. If you enter Y and do not list
any addresses, all calls will be rejected.
If you enter N, calls will only be rejected
from devices whose addresses you list on
this screen. If you enter N and do not list
any addresses, all calls will be accepted.
If you do not update this screen (data flag
is N, a default PAD security will be
downloaded that allows all calls to be
accepted.
Enter remote X.25 Lists the X.25 addresses of all PAD devices
calling address that will be accepted for connection if
below Allow access is Y or rejected for connection
if Allow access is N. Enter up to 32 remote
addresses per screen and up to 512 per
DTC/X.25 Network Access card.
You can use the letter X as a wildcard
character in place of any single digit. All
systems with corresponding addresses will
have the same access rights. The address
check is sensitive to the length of the
address. To manage addresses, you may enter
pyramids of Xs where the base is the longest
expected address and the peak is the
shortest expected address.
For example to control access to all PAD
addresses of six, seven or eight digits
starting with 1234:
Table 3-7.
----------------------------
| | |
| 1234XX | |
| | |
----------------------------
| | |
| 1234XXX | |
| | |
----------------------------
| | |
| 1234XXXX | |
| | |
----------------------------
To control access to PADs with addresses of
seven digits starting with 6789:
6789XXX
Step 14: Validate/Cross-Validate the Configuration File
Validation ensures that no conflicts exist in the network configuration
file (NMCONFIG.PUB.SYS) between the DTCs and other configuration
parameters. After NMMGR validates the network configuration file, it
will automatically cross-validate the file with the system I/O devices
configured through the SYSGEN utility. This will take place only if the
file opened at the start of the NMMGR session is NMCONFIG.PUB.SYS and
validation is successful. Additionally, you must have System Manager
(SM) capability or the cross- validation will not occur. The commands
used for SYSGEN cross-validation are in the file NMGRXVAL.PUB.SYS. If
this file does not exist, NMMGR will create the file for you before
cross-validating. You can edit this file as appropriate for your
environment.
Refer to the MPE/iX manual, System Startup, Configuration, and Shutdown
Reference Manual (32650-90042), for information on SYSGEN.
1. To validate the DTS configuration in the configuration file, press
the [Validate DTS/LINK] key at the Card Configuration screen. You
can also reach the Validate Configuration File screen by typing
validate at the command line on top of any NMMGR screen and
pressing [Enter]. (Note that the [Enter] key is not the carriage
return key.) While at the Validate screen press the [Validate
DTS/LINK] key to validate the DTS configuration.
The DTS validation procedure starts by displaying the following on
the terminal:
Table 3-8.
---------------------------------------------------
| | |
| | -> Validation of DTS/LINK started. <- |
| | |
---------------------------------------------------
| | |
| | -> Validation of DTS/LINK finished. <- |
| | |
---------------------------------------------------
If errors were encountered in the configuration file, the
validation procedure will print out the total number of errors
found. Error messages will also be displayed explaining the
problems found. Refer to appendix A, "Error Messages," for more
information about these error messages.
2. After validation of the network configuration file is complete,
the following will appear on the screen as the file is
cross-validated with the files created with SYSGEN (warning
messages may vary):
Table 3-9.

| |
----------------------------------------------------------------
| |
| |
----------------------------------------------------------------

----------------------------------------------------------------
Answer Y if you want to invoke DTCCNTRL and make DTS changes take
effect now, or answer N if you don't want DTS changes to take
effect now. Note any messages that describe additional actions
needed for changes to become active. After you exit NMMGR you can
review any actions needed by viewing the logs at the end of the
file LOGDCC.PUB.SYS.
If you answer N, the DTS changes will take effect the next time
DTCCNTRL is invoked, a DTS shutdown/restart is done, or the system
is rebooted.
Type H if you need more help to answer the question.
4. After viewing the messages describing what actions are required,
if any, enter [RETURN] when you see the prompt:
(Press RETURN when finished view screen contents.)
You will return to the Validation screen. You may make additional
configuration changes or exit NMMGR.
