TCP/IP Connectivity Utilities (5722-TC1)
Sockets over SNA
AnyNet/400 Sockets over SNA allows applications written to the sockets interface to
communicate between iSeries servers in an SNA environment. AnyNet/400 provides this with
little or no change to application programs. AnyNet/400 Sockets over SNA is compatible with
AnyNet/2 and AnyNet/MVS and, therefore, provides connectivity to workstation and host
environments.
Simple Network Management Protocol (SNMP)
Simple Network Management Protocol (SNMP) provides a means for managing an Internet
environment. SNMP is used in each node of a TCP/IP network that is monitored or managed
by an SNMP manager. An iSeries SNMP agent provides support for the exchange of network
management messages and information among hosts. OS/400 supports Management
Information Base II (MIB-II). The features included in SNMP for iSeries are:
• SNMP APIs for managing applications have the ability to manipulate management
data via local or remote SNMP agents. Using AnyNet/400 support, information can be
retrieved from systems on SNA or TCP/IP networks, which makes it easier to discover
and manage potential problems anywhere within the network.
• SNMP agents are
extendable, and APIs
are provided that allow
the dynamic addition
of sub-agents to show
additional information
needed to make good
management
decisions. OS/400
also supports a Host
Resources
Management
Information Base
(MIB) for hardware
and software inventory
of an iSeries server. Independent Software Vendors (ISVs) can use the SNMP APIs to
write iSeries management applications to collect inventory data, monitor and change
resources in the network and a variety of other tasks. They can also write sub-agents
that allow access to additional iSeries management information from management
applications running on other platforms.
• The SNMP management function is split between two kinds of entities, named the
“manager” and the “agent”. The SNMP agent function runs on the iSeries server and
allows it to be managed by network management stations that have implemented the
SNMP manager function. The OS/400 SNMP agent provides configuration,
