null Object Type
The ENTRY object also allows you to view the ATM address table which shows the
current ATM, SVC, and PVC connections on the TCP/IP process. Each ATM address
entry is displayed with the name set to ATMentry. The ATM address entries are used to
track existing ATM connections. You cannot add or delete these type of entries with
SCF.
An entry object is further broken down into one of the following types:
The ENTRY object name must be preceded by a pound sign (#) and can have at most
seven alphanumeric characters. The first character following the pound sign must be a
letter. If the ENTRY object was added dynamically, the name is left blank.
null Object Type
The null object is not an actual object type. The term “null” is used to represent the
lack of a specified object. Any SCF command that supports the null object type is
issued without the specification of an object type. Commands support the null object
type if an object type is irrelevant (as is the case with the VERSION command), or if
they refer to a collection of objects (as is the case with the NAMES command).
To issue an SCF command using the null object, specify the name of the SCF
command followed by a process name. The process name must be a valid process
name. Do not use the term “null” when you issue the command.
PROCESS Object Type
The PROCESS object is the NonStop TCP/IP subsystem run as a process on the
NonStop operating system. The PROCESS object automatically enters the started
state when the NonStop TCP/IP program is invoked. A START PROCESS command is
not necessary.
When you assign a name to a PROCESS object, you must make sure it conforms to
the conventions for process names. The recommended form for TCP/IP process
names is $ZTCx or $ZTCxx, where x is a letter or a numeric digit; for example,
$ZTC0. Most of the NonStop client and server programs expect the name of a TCP/IP
process to take this form. This convention allows applications to use a simple
screening algorithm to locate NonStop TCP/IP processes in a system.
ARP The entry is a standard ARP table entry where an IP address is
mapped into a hardware MAC address.
ATMARP The entry is an ATM ARP table entry.
ATM The entry is an ATM address table entry.
Note. In the NonStop TCP/IP subsystem, a TCP/IP process can have more than one IP
address associated with it. However, each process must have a valid process name, and each
IP address must be unique within the network.
