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 information to the network administrator.
You can use the SNMP manager to monitor the built-in EtherNet/IP port.
