NonStop TCP/IP Process

The NonStop TCP/IP subsystem provides TCP/IP data communications connectivity.

NonStop TCP/IP processes are used by the LAN adapters and SWAN concentrators.

The NonStop TCP/IP processes that support these adapters and SWAN concentrators

are preconfigured and started during the system load sequence.

For more information on the NonStop TCP/IP and NonStop TCP/IPv6 subsystems, see

the TCP/IPv6 Configuration and Management Manual and the TCP/IPv6 Configuration

and Management Manual.

For more information on LAN adapters, see the LAN Configuration and Management

Manual.

Local Area Network (LAN) Driver and Interrupt Handlers (DIHs)

NonStop TCP/IP processes can interface to the network through the ServerNet LAN

Systems Access (SLSA) subsystem. The SLSA subsystem provides QIO-based driver

and interrupt handlers (DIHs) that allow NonStop TCP/IP processes to connect to a

LAN adapter. The SLSA subsystem is preconfigured and started during the system

load sequence.

For more information on the SLSA subsystem, see the LAN Configuration and

Management Manual.

ServerNet Wide Area Network (SWAN) Concentrator

The SWAN concentrator is a communications device that provides wide area network

(WAN) connections. HP recommends that you configure the SWAN concentrator in the

same processor pair as the Expand line-handler processes.

For more information on configuring the SWAN concentrator, see the WAN Subsystem

Configuration and Management Manual.
