1. Verify that the cursor is in the Device X.25 address field. Enter the X.25 address of
the calling devices that will be associated with the following list name. You can use
the letter X as a wildcard in place of any single digit.
2. Move the cursor to the Access List Name field. Enter the list name you want to
associate with this address. If you want to deny access to this address, enter the
name of an empty or non-existent PAD access list name.
3. Continue entering X.25 address and Access List name pairs. If you need to configure
more address 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 X.25 calling
addresses can be configured.
4. 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.
5. 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.
Device X.25 Address Enter the address of the remote PAD device. Enter up to 16
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 address. 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:
1234XX
1234XXX
1234XXXX
To control access to PADS with addresses of seven digits starting
with 6789:
6789XXXX
Access List Name Enter the name of the corresponding PAD access list, created in
Step 7: Create and Modify the PAD Access Lists. The reserved
list name ALL_DEST can be used to allow the corresponding PAD
device(s) access to all nodes in the nodenames list. Note that no
password can be assigned to ALL_DEST.
Step 19: 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
