Description: Extends standard interface MIB objects with HP/Comware-specific attributes such as dampening and link-flap 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 HPN-ICF-IF-EXT-MIB?

HPN-ICF-IF-EXT-MIB is an HP Networking (Comware/H3C) vendor MIB that extends the standard IETF IF-MIB with additional interface statistics not covered by the base interfaces group, applicable broadly across routers, switches, and other HP/Comware products. It exposes periodic flow-based traffic counters (bits and packets in/out over a configurable interval) per interface, as well as interface speed-change statistics. For hardware/software status monitoring, this MIB is directly useful for tracking interface throughput trends and detecting link speed renegotiation events, both of which are classic signs of a degrading physical link, a duplex/speed mismatch, or unusual bandwidth utilization. It is explicitly documented as an extension of standard interface MIBs such as IF-MIB, meant to be used alongside it rather than in isolation. It is deployed across the HP/H3C Comware router and switch product line wherever finer-grained interface flow statistics beyond IF-MIB counters are needed. Engineers can download the HPN-ICF-IF-EXT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HPN-ICF-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

HP/H3C Comware router
HP/H3C Comware switch

Monitoring Examples

An administrator would poll hpnicfIfFlowStatTable (via hpnicfIfStatFlowInterval) and examine hpnicfIfStatFlowInBits/hpnicfIfStatFlowOutBits alongside hpnicfIfStatFlowInPkts/hpnicfIfStatFlowOutPkts and hpnicfIfStatFlowInBytes/hpnicfIfStatFlowOutBytes to track per-interface throughput over a rolling interval, revealing a sudden traffic spike or a link approaching saturation. The hpnicfIfSpeedStatTable would be checked to see how often an interface's negotiated speed has changed, which combined with hpnicfIfStatGlobalFlowInterval settings helps correlate speed flaps with observed traffic drops, pointing to a cabling or transceiver problem.

What Can Be Monitored

per-interface flow-based in/out bits
per-interface flow-based in/out packets and bytes
flow statistics interval
interface speed-change statistics

How to Use in IPNetwork Monitor

Example using hpnicfIfInNUcastPkts OID:

Select an HP/H3C Comware router or switch (extended 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 hpnicfIfInNUcastPkts 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.
