Table 3 Configure Internet address field descriptions
DescriptionField
The identifier by which this interface (port) is known on the network. It consists of
four sets of integer values (0 to 255) separated by periods (for example, 192.2.3.6).
Internet Address
The IP address must be unique for each X.25 interface. It must also specify a different
subnet from the IP address of any other X.25 or LAN interface on this system. To
obtain an IP address, see your system administrator, network administrator, or HP
representative.
The subnet mask (like IP addresses) is composed of four integers (0 to 255) separated
by periods. The subnet mask is used for routing.
Subnet Mask
When you enter an IP address, SMH places a default subnet mask in the subnet
mask field, depending on the class of IP address you enter. You may use the default
or enter another one if required. Table 4 (page 17) shows the IP addresses listed by
class and their default subnet masks).
The symbolic name (in alphanumeric format) by which this network interface will be
known on the network. Use the Add/Modify Host Name Aliases button to add or
modify aliases.
