Technical data

• Library of RPC function calls
• Portmapper service, which is a service that client programs can use
to determine the port number that another service uses. Clients use the
Portmapper Service for NFC, PC-NFS, and RPC applications.
• External data representation (XDR) routines
For more details, refer to the Compaq TCP/IP Service ONC RPC Programming
manual.
1.3.4 SNMP Programming Interface
The Extensible Simple Network Management Protocol (eSNMP) API provides
routines for developing applications that remotely manage and collect data from
network devices such as routers, bridges, and hosts.
These network devices run software that carries out management commands that
either get information from devices or set operating parameters for devices.
Other network applications send commands to network devices to perform
configuration management, monitor network traffic, or troubleshoot network
problems.
The SNMP API provides routines for the following functions:
• Establish, maintain, and terminate communication with the master agent
• Manipulate, reformat, extract, and compare data
• Control information that is written to log files
The SNMP API routines are almost identical in function and interface with the
routines in the Compaq Tru64 UNIX API.
For more details, refer to the Compaq TCP/IP Services for OpenVMS SNMP
Programming and Reference manual.
1.4 Understanding RFCs
Although TCP/IP is monitored by a number of organizations, no single entity owns
this protocol; its specifications are publicly available and are constantly growing as
communications requirements evolve.
The process by which the specifications evolve is through a mechanism called
Requests for Comments (RFCs). When someone has an idea for a new or
improved capability for TCP/IP, he or she writes a proposal, posts it on the Internet
as an Internet draft, and requests comments from the networking community.
After a review and revision cycle, working code is developed and an RFC becomes a
standard protocol.
RFCs are available on the Internet from the Internet Network Information Center
(InterNIC). The following web site provides links to several RFC international
repositories, lists all RFCs, and explains how you can obtain copies:
http://www.rfc-editor.org
Note that, although RFCs recommend implementation guidelines, the actual
implementation of an RFC can and must differ from the RFC in minor ways. When
product documentation refers to specific RFCs, be aware that the RFC only sets the
standard for development. Product developers must design their software for the
specific environment and requirements of their customers.
