Description: Manages NVGRE (Network Virtualization using GRE) tunnel endpoints and virtual subnet identifiers on HP/Comware.

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-NVGRE-MIB?

HPN-ICF-NVGRE-MIB is an HP Comware vendor-specific MIB that manages NVGRE (Network Virtualization using Generic Routing Encapsulation) tunnel endpoints and virtual subnet identifiers for network-virtualization overlays on HP switching platforms. Its hpnicfNvgreTable defines each NVGRE instance by hpnicfNvgreID (4096–16777214) and binds it to a Virtual Switch Instance via hpnicfNvgreVsiIndex, tracking hpnicfNvgreRemoteMacCount and lifecycle via hpnicfNvgreRowStatus, while hpnicfNvgreTunnelTable exposes per-tunnel hpnicfNvgreTunnelOctets and hpnicfNvgreTunnelPackets Counter64 traffic counters. Remote MAC reachability is tracked in hpnicfNvgreMacTable and hpnicfNvgreStaticMacTable, distinguishing self-learned, static-configured, and protocol-learned MAC entries bound to specific tunnels, and hpnicfNvgreTunnelBoundTable reports how many NVGREs share a given tunnel. It depends on HPN-ICF-OID-MIB for its OID placement under hpnicfCommon and is deployed on HP/H3C Comware switches acting as NVGRE tunnel endpoints in virtualized data center networks, where an engineer troubleshooting overlay connectivity would open the HPN-ICF-NVGRE-MIB MIB Browser view to inspect tunnel and MAC-mapping state.

IPNetwork Monitor allows you to monitor SNMP objects defined in HPN-ICF-NVGRE-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 switches (NVGRE-capable network-virtualization gateways)

Monitoring Examples

An operator polls hpnicfNvgreTunnelTable for hpnicfNvgreTunnelOctets/Packets on a given hpnicfNvgreTunnelID to confirm traffic is flowing over an NVGRE tunnel, then checks hpnicfNvgreMacTable to verify a remote MAC address resolves to that tunnel; a MAC address missing from the table or a tunnel counter that stops incrementing would indicate a broken NVGRE overlay path between virtual switch instances.

What Can Be Monitored

NVGRE instance table (ID, VSI binding, row status)
per-tunnel octet/packet counters
remote MAC address table and learning type
static remote MAC configuration
tunnel-to-NVGRE binding count

How to Use in IPNetwork Monitor

Example using hpnicfNvgreTunnelOctets OID:

Select an HP/H3C Comware switch (NVGRE network-virtualization gateway) 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 hpnicfNvgreTunnelOctets 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 octets that have been forwarded over the tunnel. 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.
