About SNMP

Use the SNMP tab in Control Expert to configure SNMP parameters for these Quantum Ethernet I/O modules:

  • head module on the local rack (140CRP31200)

  • adapter module on the remote drop (140CRA31200 or BMXCRA312•0)

An SNMP v1 agent is a software component of the SNMP service that runs on these modules to allow access to diagnostic and management information for the modules. You can use SNMP browsers, network management software, and other tools to access this data. In addition, the SNMP agent can be configured with the IP addresses of 1 or 2 devices (typically PCs that run network management software) to be the targets of event-driven trap messages. Such messages inform the management device of events like cold starts and the inability of the software to authenticate a device.

Access the SNMP Tab

Double-click these modules in the Control Expert configuration to access their SNMP tabs:

  • 140CRP31200 head module (local rack)

  • 140CRA31200 or BMXCRA312•0 adapter module (remote drop)

The SNMP tab appears:

Use the SNMP tab to configure the SNMP agents for the communication modules in the local rack and remote drop. The SNMP agent can connect to and communicate with 1 or 2 SNMP managers as part of an SNMP service. The SNMP service includes:

  • authentication checking, by the Ethernet communication module, of any SNMP manager that sends SNMP requests

  • management of events or traps
