Cluster I/O Protocols (CIP) Configuration and Management Manual (H06.16+, J06.05+)

Telco connectivity with management facilities and Telco applications on the NonStop host and
Telco protocols on the CLIM. The CIP subsystem resides partly on the NonStop host system and
partly on the CLIM.
In the CIP subsystem, IP functionality is distributed between the NonStop system and the CLIM.
Figure 2: Distribution of Functionality in the CIP Subsystem shows this distribution of functionality.
Figure 2 Distribution of Functionality in the CIP Subsystem
CIP includes a NonStop host system subsystem that provides:
• An application programmatic interface (API)
• Transport service providers
• A Subsystem Control Facility (SCF) interface for monitoring the subsystem and for configuring
host-to-CLIM relationships
NOTE: There are some migration considerations when porting applications from conventional
and Parallel Library TCP/IP and NonStop TCP/IPv6 to CIP. See Chapter 6 (page 174).
CIP provides a socket access method (SAM) process on the NonStop system for applications to
use as a transport service provider.
Monitoring and management of the CIP subsystem on the NonStop system is provided by SCF and
by the CLIMCMD CLI. See Chapter 10 (page 216), for more information.
You use the CLIMCMD climconfig tool to add, modify, delete, and display information in the
network, IPSec, and Failover configuration files. For more information about the climconfig tool,
see “Climconfig (Man Pages)” (page 301).
IP Protocols
IP CIP supports these protocols:
• Transmission Control Protocol/Internet Protocol (TCP/IP) (including IPv6 and IPv4)
• User Datagram Protocol (UDP)
• Stream Control Transmission Protocol (SCTP)
• IP Security (IPSec)
Telco Protocols
Telco CIP supports the Message Transfer Part Level 3 User Adaptation layer (M3UA) protocol.
Multiple CLIMs per Provider
Multiple IP and Telco CLIMs can be configured in the same IPDATA Provider. This feature provides
scalability for applications that need high bandwidth. Unless the MULTIPROV attribute is set for
multiple providers, as described under “Multiple Providers per CLIM”, a CLIM can only belong to
one IPDATA Provider, but a maintenance provider can also be configured to use it.
