Description: Huawei MIB with vendor-specific objects for managing tunnels of various types, including GRE and IPv6-in-IPv4.
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 HUAWEI-TUNNEL-EXT-MIB?
HUAWEI-TUNNEL-EXT-MIB is a Huawei-proprietary module providing extended tunnel-management objects for GRE, IPv6-in-IPv4, and other encapsulated tunnel types on Huawei routers, including binding-type and TSU (tunnel service unit) definitions. It exposes tunnel binding configuration, TSU assignment, and endpoint/tunnel-type data layered on top of the tunnel interfaces created elsewhere on the device. Its monitoring value lies in hardware/software interface status: the operational up/down state of each tunnel reveals whether encapsulated traffic is actually flowing, which is essential where a GRE or IPv6-transition tunnel carries production VPN or transition traffic. It extends the standard tunnel-management concepts of RFC 2667's TUNNEL-MIB with Huawei-specific binding and TSU objects, and it relies on IF-MIB for the underlying tunnel interface indices. It is typically deployed on Huawei routers running GRE tunnels or IPv6-in-IPv4 transition tunnels for VPN interconnection or IPv6 migration. Network engineers evaluating or troubleshooting this functionality can download the HUAWEI-TUNNEL-EXT-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in HUAWEI-TUNNEL-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
- Huawei routers/gateways supporting GRE and IPv6-in-IPv4 tunneling
Monitoring Examples
An admin would poll a tunnel-binding table (an hwTunnelExtTable/hwTunnelBindTable pattern) for each tunnel's binding type, TSU assignment, and endpoint addresses. A tunnel reporting a down operational state points to a lost route to the remote tunnel endpoint or a source-address change breaking the GRE encapsulation. Checking the TSU binding after a configuration change confirms traffic is being correctly steered into the intended tunnel service unit rather than falling back to a default path.
What Can Be Monitored
- tunnel binding type/configuration
- tunnel operational (up/down) status
- TSU (tunnel service unit) assignment
- tunnel endpoint addresses
