Configuring the SNMP Agent
Original instructions
About us
Introduction
The BMENOC0321 control network module includes an SNMP v1 agent. An SNMP agent is a software component running on the communication module that allows access to the module's diagnostic and management information via the SNMP service.
SNMP browsers, network management software, and other tools typically use SNMP to access this data. In addition, the SNMP agent can be configured with the IP address of up to two devices (typically PCs running network management software) to be the target of event driven trap messages. These trap messages inform the management device of events such as cold start and unauthorized access.
Use the SNMP page to configure the SNMP agent in the BMENOC0321 module. The SNMP agent can communicate with up to two SNMP managers as part of an SNMP service.
