Description: HH3C MIB for OpenFlow Protocol (OFP) configuration and statistics on H3C SDN-capable switches.

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 HH3C-OFP-MIB?

HH3C-OFP-MIB is an H3C proprietary MIB covering the OpenFlow Protocol (OFP) module used on H3C's SDN-capable switches, where an OpenFlow instance connects to one or more external SDN controllers. It exposes per-instance controller configuration and connection data, including controller role, transport type, SSL policy, VRF binding, and IP/port addressing. Its primary monitoring value is control-plane software status: whether the switch's OpenFlow instance is actually connected to its controller (hh3cOfpInstanceCtrConnectState), which connection type and security policy are in use, and it also defines a trap object (hh3cOfpMibTrapOid) for controller connectivity events, making it directly useful for fault detection rather than hardware health. It depends on general SDN/OpenFlow protocol concepts and, on multi-VRF devices, interacts with VRF-aware routing MIBs. It is deployed in SDN-controlled data-center or campus networks where H3C switches act as OpenFlow-managed forwarding elements under a centralized controller, and administrators typically load the HH3C-OFP-MIB MIB into their SNMP management platform to monitor controller connectivity.

IPNetwork Monitor allows you to monitor SNMP objects defined in HH3C-OFP-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

H3C SDN-capable switches (OpenFlow-enabled)

Monitoring Examples

An operator would poll hh3cOfpInstanceControllerTable/hh3cOfpInstanceControllerEntry, keyed by hh3cOfpInstanceID and hh3cOfpInstanceControllerID, to check hh3cOfpInstanceCtrConnectState for each configured controller. If this state drops from connected to disconnected while hh3cOfpInstanceCtrIPaddress and hh3cOfpInstanceCtrPort remain unchanged, it signals a lost SDN control-plane session that could leave forwarding tables stale. The associated hh3cOfpMibTrap can notify management systems of such connectivity changes in near real time.

What Can Be Monitored

OpenFlow controller connection state
controller role (master/slave/equal)
controller connection type and SSL policy
controller IP address and port
VRF binding of controller session

How to Use in IPNetwork Monitor

Example using hh3cOfpInstanceControllerRole OID:

Select an H3C SDN-capable switch (OpenFlow controller connectivity) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type hh3cOfpInstanceControllerRole into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The value of the controller's role. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is an INTEGER-type OID, Value bounds is the most useful condition here — trigger an alert if the value changes unexpectedly, since which role is correct for this controller depends on your OpenFlow topology and an unplanned change often indicates a fault or misconfiguration. Click Finish to create the monitor; you can adjust any parameter later.
