Use the SNMP tab in Control Expert to configure individual SNMP parameters for these modules:

  • M580 CPU modules

  • (e)X80 EIO adapter modules on RIO drops

  • 140CRA3120• RIO adapter modules in Quantum EIO systems

An SNMP 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, as defined by the supported MIBs: MIB2, Bridge MIB, and LLDP MIB.

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 one or two devices (typically PCs that run network management software) to be the targets of event-driven trap messages. Traps can inform the management device of the following events: Link up, Link down, Cold start, Warm start, and Authentication failure.

Use the SNMP tab to configure the SNMP agents for communication modules in the local rack and RIO drops. The SNMP agent can connect to and communicate with one or two 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

SNMP V1 and SNMP V3

M580 CPU modules with firmware version ≥ 4.01 and higher support both:

  • SNMP V1.

  • SNMP V3, with the SNMPSecurityLevel of NoAuthNoPriv.

M580 CPU modules with firmware version < 4.01 support only SNMP V1.

IP Address Managers 1, 3

IP Address Manager 1

The IP address of the first SNMP manager to which the SNMP agent sends notices of traps.

IP Address Manager 2

The IP address of the second SNMP manager to which the SNMP agent sends notices of traps.

Agent 1, 3

Location

The device location (32 characters maximum).

Contact

Information describing the person to contact for device maintenance (32 characters maximum)

SNMP Manager

Select one:

  • Disabled: You can edit the Location and Contact settings on this page.

  • Enabled: You cannot edit the Location and Contact settings on this page. (Those settings are managed by the SNMP Manager.)

Community Names 1

Get

Password required by the SNMP agent before executing read commands from an SNMP manager (default = public).

Set

Password required by the SNMP agent before executing write commands from an SNMP manager (default = private).

Trap

Password an SNMP manager requires from the SNMP agent before the manager accepts trap notices from the agent (default = alert).

Security 1

Enable Authentication Failure Trap

TRUE causes the SNMP agent to send a trap notice to the SNMP manager if an unauthorized manager sends a Get or Set command to the agent (default = Disabled).

Username 3

The username value required for SNMP V3 communication.

1. Supported by SNMP V1.
