Description: Provides extended interface management objects supplementing IF-MIB for H3C device-specific interface features.

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-IF-EXT-MIB?

HH3C-IF-EXT-MIB is a vendor-specific H3C (Hangzhou H3C Technologies) MIB that supplements the standard IF-MIB with additional interface-level statistics and configuration objects for H3C routers and switches. Its core is the hh3cIfFlowStatTable, which reports sampled inbound/outbound bit rates, packet counts, and byte counts per interface over a configurable global or per-interface sampling window (hh3cIfStatGlobalFlowInterval, hh3cIfStatFlowInterval), plus a companion hh3cIfSpeedStatTable reporting averaged packet/byte rates over that same interval. Later revisions extended the module with sub-interface/parent-interface relationship tables, link-mode tracking, MTU/bandwidth objects, non-unicast packet counters, and trap configuration, all keyed off the standard ifIndex. Monitoring it gives finer-grained, sampling-window-based throughput visibility than the base IF-MIB counters alone provide, useful for detecting traffic spikes or asymmetric in/out load on a specific interface. It's an extension layered directly on IF-MIB and deployed on H3C routers and switches, and administrators can download the HH3C-IF-EXT-MIB file to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HH3C-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 routers and switches

Monitoring Examples

An operator sets hh3cIfStatFlowInterval on a WAN interface and polls hh3cIfStatFlowInBits/OutBits each interval; a sustained inbound value near link capacity while outbound stays low would indicate a one-directional traffic surge, such as an inbound flood or a large download, worth investigating.

What Can Be Monitored

sampled interface in/out bit rate
sampled interface in/out packet and byte counts
averaged packet/byte speed statistics
flow sampling interval configuration
sub-interface/parent-interface relationship tables
interface trap configuration

How to Use in IPNetwork Monitor

Example using hh3cIfInNUcastPkts OID:

Select an H3C router/switch (extended per-interface flow 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 hh3cIfInNUcastPkts 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.
