Sensitive and Nonsensitive SCF Commands
You cannot enter more than 2048 characters for any input command.
Sensitive and Nonsensitive SCF Commands
SCF commands are either sensitive or nonsensitive. A sensitive command can change
the summary state or configuration of subsystem objects, start or stop tracing, or change
the values of statistics counters. A nonsensitive command can request information or
status but cannot affect operation.
To protect the integrity of the NonStop™ IPX/SPX subsystem, the Subsystem Control
Point (SCP) allows only certain users to execute sensitive commands. SCP limits the use
of sensitive commands to members of the super ID or members of the user group that
owns the $ZMGR process.
Any user may issue nonsensitive commands.
SCF Online Help
Enter the SCF HELP command to access the interactive online help facility. If you enter
the HELP command by itself, SCF responds with a menu that guides you through the
available help options.
Using this menu-mode help facility, you can obtain general information about basic SCF
components, such as attributes, character strings, commands, filenames, integers, and so
on.
In addition to general SCF information, you can obtain information specific to
NonStop™ IPX/SPX.
To obtain information on the syntax of NonStop™ IPX/SPX object types and the
commands that apply to them, enter the following command:
HELP IPXSPX [ command ] [ object-type ]
Specifying Processes, LIF Names, and Filter Protocols in SCF
Commands
NonStop™ IPX/SPX supports the major frame types used on Ethernet or token-ring
LANs. Each frame type has a corresponding filter protocol.
Before you add an IPXPROTO process, you must specify the logical interface (LIF)
where it is to run along with the filter protocol that corresponds to the LAN frame type.
When adding an IPXPROTO process, you must specify the following for the PROCESS
object:
Note. SCF accepts input from either a terminal or a disk (OBEY) file and directs output to a
terminal, disk file, or printer. However, in this manual, all examples assume that you use a
terminal for both input and output.
Note. Tracing is sensitive because it can cause performance degradation.
