Operating System/400, 5769-SS1
TCP/IP, as part of the OS/400, supports:
– Packet Internet Groper (PING)
– Network Status (NETSTAT)
– Sockets API
– Simple Network Management Protocol (SNMP)
NETSTAT , the network status function on the AS/400 system, provides information about
the status of TCP/IP network interfaces, routes, and connections on a local AS/400
system.
Sockets API allows unrelated processes to exchange data locally and over networks.
Both connection-oriented and connectionless communication are provided for TCP/IP.
SNMP is the protocol for systems management used in TCP/IP networks. Simple Network
Management Protocol is the industry standard for managing networks in the worldwide
TCP/IP Internet environment.
Elements provided with OS/400 include SNMP agent, SNMP framework, and TCP/IP
protocol support. The TCP/IP communications protocol is enhanced with network
management capabilities to support SNMP control.
The SNMP management function is split between two kinds of entities: the “manager” and
the “agent.” The SNMP agent function runs on the AS/400 system and allows it to be
managed by network management stations that have implemented the SNMP manager
function. The SNMP framework provides the ability to write SNMP applications on the
AS/400 system.
The APIs for SNMP managing applications have the ability to manipulate SNMP
management data using SNMP agents either locally or remotely. By using Anynet/400
support, SNMP information can be retrieved from Anynet-configured systems on SNA or
TCP/IP networks. This makes it easier to discover and manage potential problems
anywhere within the network.
SNMP Enhancements at V4R5
Placing printers in a TCP/IP network on a LAN is common practice today. OS/400 V4R5
gives you the option to send print files to those printers and manage responses from
those printers in this network. This option is configured in the OS/400 print device
description and is based on the industry-standard Simple Network Management Protocol
(SNMP). It supports SNMP printers that support the printer message information block
(MIB).
Prior to V4R5, to print to ASCII printers with the output from the Host Print Transform,
either the current Printer Job Language (PJL) driver or Line Print Requestor (LPR) is
used. At V4R5, the new SNMP driver allows more printers to be accessed from an
AS/400 system with the same capabilities seen with direct attached printers or those
using the PJL driver.
