1. In the IP address field, enter the internet protocol (IP) address for the node being
configured. An example of an address is: C 192.191.191 009
2. The IP subnet mask is optional. If entering one, tab to the IP subnet mask field and
enter the number in the same format as an IP address. The 32-bit mask is grouped in
octets expressed as decimal integers and delimited by either a period (.) or a space.
The mask identifies which bits of an IP address will be used to define a subnetwork.
To determine these bits, you first need to estimate how many subnetworks and nodes
per subnetwork you need. For details on deriving an IP subnet mask, refer to the
HP 3000/iX Network Planning and Configuration Guide.
3. Move to the first Link Name field. Enter a link name to represent the DTC/X.25
Network Access card for which you are configuring a link. This name must be unique
to both the node and the DTC. The link name must be the same as the link name
configured for this card on the DTC X.25 Card Configuration — Sys-to-Sys LUGs
screen during the DTC configuration see Chapter 3, “Configuring DTCs
Step-by-Step.”
