Description: H3C MIB extending standard interface management with additional H3C-specific interface attributes and counters.

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 H3C-IF-EXT-MIB?

H3C-IF-EXT-MIB is an H3C private-enterprise MIB that extends the standard interface MIB (IF-MIB) with additional H3C-specific interface attributes, applicable across routers, switches, and other H3C products, with some objects relevant only to specific product lines. It exposes flow-based traffic statistics per interface over a configurable measurement interval, including inbound/outbound bits, bytes, and packets, plus a separate interface-speed statistics table. Its monitoring emphasis is interface performance and traffic-throughput status: an operator tracks real-time and interval-based throughput per interface to detect congestion, unexpected traffic drops, or a link running at an unexpected speed. It explicitly states its dependency on standard interface MIBs such as IF-MIB, being designed as a companion extension rather than a standalone replacement. Deployment context is H3C routers and switches across enterprise and carrier networks needing finer-grained, vendor-specific interface traffic visibility beyond what IF-MIB alone provides. Engineers can download the H3C-IF-EXT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in H3C-IF-EXT-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 router/switch

Monitoring Examples

An administrator sets h3cIfStatGlobalFlowInterval and then polls h3cIfFlowStatTable/h3cIfStatEntry for h3cIfStatFlowInBits, h3cIfStatFlowOutBits, h3cIfStatFlowInPkts, and h3cIfStatFlowOutPkts per interface to compute real-time throughput trends. A sudden drop in h3cIfStatFlowOutBits despite a steady h3cIfStatFlowOutPkts count would suggest smaller average frame sizes or a speed/duplex issue, which can be cross-checked against h3cIfSpeedStatTable/h3cIfSpeedStatEntry for the interface's actual negotiated speed.

How to Use in IPNetwork Monitor

Example using h3cIfInNUcastPkts OID:

Select an H3C router/switch (extended per-interface traffic statistics) 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 h3cIfInNUcastPkts 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 number of non-unicast (i.e., subnetwork- broadcast or subnetwork-multicast) packets delivered to a higher-layer protocol. 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 a Counter64-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.

Sub interfaces are logical virtual interfaces configured on a main interface. The main interface can be either a physical interface (such as a Layer 3 Ethernet interface) or a logical interface (such as an MFR interface). The subinterfaces on a main interface share the physical layer parameters of the main interface but can have link layer and network layer parameters of their own. Disabling or enabling a subinterface does not affect the main interface, but the main interface status change affects the subinterfaces. The subinterfaces cannot operate normally unless the main interface is connected. A single physical interface containing multiple subinterfaces enables you to network in a more flexible way. You can create subinterfaces for the following physical interfaces: Ethernet interface. An Ethernet subinterface associated with no VLAN supports only IPX, while an Ethernet subinterface associated with a VLAN supports both IP and IPX. WAN interfaces with their data link layer protocols being frame relay, whose subinterfaces support IP and IPX. WAN interfaces with their data link layer protocols being X.25, whose subinterfaces support IP and IPX. ATM interface, whose subinterfaces support only IP.
