IP subnet
mask An IP subnet mask is specified 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. An IP mask is used when
configuring subnetworks. 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. See Chapter 2, “Networking
Concepts,” for details on deriving an IP subnet mask.
Link name The link name can have up to eight alphanumeric
characters and the first character must be alphabetic.
Physical Path
The physical path number corresponds to the slot
location of a node’s programmable serial interface (PSI)
card. Recommended slot locations and physical path
calculations vary according to the type of HP 3000
system you are running. If you are unsure of the slot
location or of the physical path number to configure for
your system, see your system documentation or consult
your Hewlett-Packard service representative.
Speed The line transmission speed is given in bits per second.
For direct connect the value, must be supported by the
cable. Values are 1200, 2400, 4800, 9600, 19200, 38400,
56000, and 64000. The default is 56000.
Type Enter DD (direct dial) if you always want to call the
same host over a dial link. If you choose DD the remote
host does not have to be adjacent and other nodes can
be accessed through the remote host. Enter SD if you
want to call more than one adjacent remote node over a
dial link without reconfiguring. If you choose SD, no
other remote nodes can be accessed through the remote
host; it is an end point in the connection. Enter DC if the
link is a leased line, private line, or other non-switched
link.
