13-1 SNMP Agent

The SNMP (simple network management protocol) is a network management protocol. You can use the
SNMP to manage any network that consists of devices that support SNMP. The server that manages
the network is called the SNMP manager. The managed network devices are called SNMP agents.

13-1-1 Overview

SNMP Agent
The built-in EtherNet/IP port has its own management information called the MIB (management infor-
mation base). This information can be provided to the SNMP manager. The SNMP manager is software
that gathers and processes information about devices on the SNMP network and provides that informa-
tion to the network administrator. You can use the SNMP manager to monitor the built-in EtherNet/IP
port.

The SNMP manager has a SNMP command to request MIB information. The built-in EtherNet/IP port
SNMP agent function supports SNMPv1 (RFC1157) and SNMPv2C (RFC1901). Use the SNMPv1 or
SNMPv2C protocol to manage the built-in EtherNet/IP port with the SNMP manager. You can also use
both the SNMPv1 and SNMPv2C protocols together at the same time.
