SRCIPPORT n
This modifier is applicable to Expand-over-IP line-handler processes only. This
modifier specifies the Internet Protocol (IP) address associated with the NonStop
TCP/IP process used by the local Expand-over-IP line-handler process. Because a
NonStop TCP/IP process can have more than one IP address, you must specify to the
Expand-over-IP line-handler process which IP address to use.
The address must be specified by number (for example, 130.252.12.3). It is not
validated and need not be accessible. Configuring IP addresses is explained in the
TCP/IP Configuration and Management Manual.
SRCIPPORT n
Default: 1024
Units: Not applicable
Range: 0 through 65534
This modifier is applicable to Expand-over-IP line-handler processes only. This
modifier specifies the User Datagram Protocol (UDP) port number used by the local
Expand-over-IP line-handler process. UDP port numbers are explained in the TCP/IP
Configuration and Management Manual.
STARTUP_OFF/STARTUP_ON
Default: STARTUP_OFF
Units: Not applicable
Range: ON or OFF
These Layer 2 modifiers are applicable to all Expand line-handler process types. The
STARTUP_OFF modifier specifies that the line will be disabled after a system load.
The STARTUP_ON modifier specifies that the line is brought up automatically after a
system load.
SUPERPATH_OFF/SUPERPATH_ON
Default: SUPERPATH_OFF
Units: Not applicable
Range: ON or OFF
These modifiers apply to all Expand line types except for Expand-over-ServerNet. The
SUPERPATH_ON modifier enables the Expand multi-CPU feature, which allows you to
spread the communications load over multiple processors by connecting multiple
Expand line-handler processes, each in a separate processor, between two adjacent
nodes. These Expand line-handler processes are regarded as a single path by the
Expand subsystem. multi-line paths can be part of a multi-CPU path. The Expand
multi-CPU feature significantly increases the maximum throughput of an Expand path,
especially for Expand-over-IP connections.
When the SUPERPATH_ON modifier is specified and there is an existing multi-CPU
path, the new path joins the multi-CPU path. If there is no existing multi-CPU path,
then a multi-CPU path is created that has the new path as its sole member. There can
