Description: Manages GRE tunnel interface configuration and keepalive statistics on H3C routing platforms.
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-GRE-MIB?
HH3C-GRE-MIB is an H3C (Hangzhou H3C Technologies) enterprise MIB that manages Generic Routing Encapsulation (GRE) tunnel interfaces on H3C routing and switching platforms. It exposes configuration objects for GRE tunnel setup along with keepalive statistics used to track tunnel liveness. As a monitoring tool it is used primarily to check the operational and configuration state of GRE tunnels rather than deep hardware health, though tunnel keepalive failures can indicate underlying interface or software issues. It complements the standard IETF TUNNEL-MIB and IF-MIB, since GRE tunnels are represented as logical interfaces in the ifTable. It is typically deployed on H3C routers and Layer 3 switches that terminate GRE tunnels for site-to-site connectivity or protocol encapsulation. Engineers can download the HH3C-GRE-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in HH3C-GRE-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
- H3C Layer 3 switch
Monitoring Examples
No sample objects were captured for this module, so specific table names are not confirmed, but based on its stated purpose an admin would poll GRE tunnel configuration and keepalive counters to confirm a tunnel remains up and is exchanging keepalive packets with its peer. A rise in missed keepalives or a tunnel dropping to a down operational state would signal a routing or connectivity problem needing investigation. This description avoids inventing specific object or table names given the absence of sample data.
What Can Be Monitored
- GRE tunnel configuration
- tunnel keepalive status
- tunnel operational state
