Description: Manages OpenFlow controller connections and flow table statistics for Dell Networking equipment.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is DELL-NETWORKING-OPENFLOW-MIB?

DELL-NETWORKING-OPENFLOW-MIB is a Dell Networking OS enterprise MIB that exposes SDN OpenFlow status on Dell Networking switches, covering configured OpenFlow instances, the controllers managing them, and the ports, VLANs, and flows/flow-actions associated with each instance. It provides configuration and operational visibility into the switch's OpenFlow-enabled forwarding behavior, letting management systems see which controller owns an instance and which physical resources (ports, VLANs) participate in it. From a monitoring standpoint this is primarily a software/control-plane status MIB: it would reveal whether an OpenFlow instance has an active controller connection and how many flows/flow-actions are currently programmed, which is critical to confirming SDN control is functioning rather than silently disconnected. No concrete object or table names were available in this extract, so specific field names cannot be confirmed, but the module description indicates instance, controller, port, VLAN, and flow/flow-action data are all exposed. It is deployed in Dell Networking switch environments participating in SDN/OpenFlow-controlled networks, typically in data centers using centralized SDN controllers. Engineers can download the DELL-NETWORKING-OPENFLOW-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DELL-NETWORKING-OPENFLOW-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Dell Networking switches (Dell Networking OS, OpenFlow-enabled)

Monitoring Examples

No sample object names were available in this extract, so a concrete polling scenario citing real object names cannot be honestly constructed. Based on the module description, an operator would generally poll this MIB to confirm each configured OpenFlow instance shows an active controller connection, and to check flow/flow-action counts for unexpected drops indicating an SDN control-plane disconnect, but exact object/table names are not confirmed here.

What Can Be Monitored

OpenFlow instance configuration
controller connection per instance
ports assigned to OpenFlow instances
VLANs assigned to OpenFlow instances
flows and flow actions programmed
