Description: H3C MIB for generic tunnel interface management covering GRE, IP-in-IP, and other encapsulation tunnel types.

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 H3C-TUNNEL-MIB?

H3C-TUNNEL-MIB is a vendor-specific MIB from H3C covering configuration and monitoring of generic tunnel interfaces such as GRE and IP-in-IP encapsulation on H3C routers and switches. It exposes a tunnel interface table with encapsulation method, hop limit, security mode, TOS/flow-label handling, address family, and local/remote endpoint addresses, plus related tunnel inet configuration objects. For monitoring, it lets an operator confirm operational parameters and endpoint addressing of each tunnel, useful for verifying correct provisioning and troubleshooting reachability or encapsulation mismatches. It builds on general IETF tunnel/interface conventions in spirit but is an H3C-proprietary table structure. It is deployed on H3C routers/Layer 3 switches building overlay tunnels for VPN, IPv6-over-IPv4, or WAN backhaul. Engineers can download the H3C-TUNNEL-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in H3C-TUNNEL-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 Layer 3 switch

Monitoring Examples

An administrator would poll h3cTunnelIfTable/h3cTunnelIfEntry to check h3cTunnelIfEncapsMethod, h3cTunnelIfLocalInetAddress, and h3cTunnelIfRemoteInetAddress for each tunnel, confirming expected encapsulation and matching endpoint addresses. An unexpected h3cTunnelIfHopLimit or h3cTunnelIfSecurity setting, or an address mismatch, would reveal a misconfigured tunnel causing dropped or insecure traffic.

What Can Be Monitored

tunnel interface encapsulation method
tunnel local/remote endpoint address
tunnel hop limit
tunnel security mode
tunnel TOS/flow label settings

H3C h3cTunnelIfEncapsMethod	1.3.6.1.4.1.2011.10.2.53.1.1.1.1.3	H3cTunnelType	read-write	The encapsulation method used by the tunnel.
I32 h3cTunnelIfHopLimit	1.3.6.1.4.1.2011.10.2.53.1.1.1.1.4	Integer32	read-only	The IPv4 TTL or IPv6 Hop Limit to use in the outer IP header. A value of 0 indicates that the value is copied from the payload's header.
INT h3cTunnelIfSecurity	1.3.6.1.4.1.2011.10.2.53.1.1.1.1.5	INTEGER	read-only	The method used by the tunnel to secure the outer IP header. The value ipsec indicates that IPsec is used between the tunnel endpoints for authentication or encryption or both. More specific security-related information may be available in a MIB module for the security protocol in use.
I32 h3cTunnelIfTOS	1.3.6.1.4.1.2011.10.2.53.1.1.1.1.6	Integer32	read-only	The method used to set the high 6 bits (the differentiated services codepoint) of the IPv4 TOS or IPv6 Traffic Class in the outer IP header. A value of -1 indicates that the bits are copied from the payload's header. A value of -2 indicates that a traffic conditioner is invoked and more information may be available in a traffic conditioner MIB module. A value between 0 and 63 inclusive indicates that the bit field is set to the indicated value.
IPV h3cTunnelIfFlowLabel	1.3.6.1.4.1.2011.10.2.53.1.1.1.1.7	IPv6FlowLabelOrAny	read-only	The method used to set the IPv6 Flow Label value. This object need not be present in rows where h3cTunnelIfAddressType indicates the tunnel is not over IPv6. A value of -1 indicates that a traffic conditioner is invoked and more information may be available in a traffic conditioner MIB. Any other value indicates that the Flow Label field is set to the indicated value.
IPt h3cTunnelIfAddressType	1.3.6.1.4.1.2011.10.2.53.1.1.1.1.8	InetAddressType	read-write	The type of address in the corresponding h3cTunnelIfLocalInetAddress and h3cTunnelIfRemoteInetAddress objects.
IP h3cTunnelIfLocalInetAddress	1.3.6.1.4.1.2011.10.2.53.1.1.1.1.9	InetAddress	read-write	The address of the local endpoint of the tunnel (i.e., the source address used in the outer IP header). If the address is unknown, the value is 0.0.0.0 for IPv4 or :: for IPv6. The type of this object is given by h3cTunnelIfAddressType.
IP h3cTunnelIfRemoteInetAddress	1.3.6.1.4.1.2011.10.2.53.1.1.1.1.10	InetAddress	read-write	The address of the remote endpoint of the tunnel (i.e., the destination address used in the outer IP header). If the address is unknown or the tunnel is not a point-to-point link (e.g., if it is a 6to4 tunnel), the value is 0.0.0.0 for tunnels over IPv4 or :: for tunnels over IPv6. The type of this object is given by h3cTunnelIfAddressType.
I32 h3cTunnelIfEncapsLimit	1.3.6.1.4.1.2011.10.2.53.1.1.1.1.11	Integer32	read-only	The maximum number of additional encapsulations permitted for packets undergoing encapsulation at this node. A value of -1 indicates that no limit is present (except as a result of the packet size).
h3cTunnelInetConfigTable	1.3.6.1.4.1.2011.10.2.53.1.1.3		not-accessible	The (conceptual) table containing information on configured tunnels. This table can be used to map a set of tunnel endpoints to the associated ifIndex value. It can also be used for row creation. Note that every row in the h3cTunnelIfTable with a fixed destination address should have a corresponding row in the h3cTunnelInetConfigTable, regardless of whether it was created via SNMP.
h3cTunnelInetConfigEntry	1.3.6.1.4.1.2011.10.2.53.1.1.3.1		not-accessible	An entry (conceptual row) containing the information on a particular configured tunnel.
I32 h3cTunnelInetConfigSlot	1.3.6.1.4.1.2011.10.2.53.1.1.3.1.1	Integer32	not-accessible	Slot number. h3cTunnelInetConfigSlot, h3cTunnelInetConfigSubSlot and h3cTunnelInetConfigTunnNum descirbe a tunnel interface. For Example, interface tunnel 0/0/25 would be configured as: h3cTunnelInetConfigSlot 0 h3cTunnelInetConfigSubSlot 0 h3cTunnelInetConfigTunnNum 25
I32 h3cTunnelInetConfigSubSlot	1.3.6.1.4.1.2011.10.2.53.1.1.3.1.2	Integer32	not-accessible	Sub slot number. As described in h3cTunnelInetConfigSlot's description.
I32 h3cTunnelInetConfigTunnNum	1.3.6.1.4.1.2011.10.2.53.1.1.3.1.3	Integer32	not-accessible	Tunnel number. As described in h3cTunnelInetConfigSlot's description.
NUM h3cTunnelInetConfigIfIndex	1.3.6.1.4.1.2011.10.2.53.1.1.3.1.6	InterfaceIndexOrZero	read-only	If the value of h3cTunnelInetConfigStatus for this row is active, then this object contains the value of ifIndex corresponding to the tunnel interface. A value of 0 is not legal in the active state, and means that the interface index has not yet been assigned.
ROW h3cTunnelInetConfigStatus	1.3.6.1.4.1.2011.10.2.53.1.1.3.1.7	RowStatus	read-create	The status of this row, by which new entries may be created, or old entries deleted from this table. The agent need not support setting this object to createAndWait or notInService since there are no other writable objects in this table, and writable objects in rows of corresponding tables such as the h3cTunnelIfTable may be modified while this row is active. To create a row in this table, the management station should set h3cTunnelInetConfigSlot, h3cTunnelInetConfigSubSlot, h3cTunnelInetConfigTunnNum, and set h3cTunnelInetConfigStatus to createAndGo. Creating a row in this table will cause an interface index to be assigned by the agent in an implementation-dependent manner, and corresponding rows will be instantiated in the ifTable and the h3cTunnelIfTable. The status of this row will become active as soon as the agent assigns the interface index, regardless of whether the interface is operationally up. Deleting a row in this table will likewise delete the corresponding row in the ifTable and in the h3cTunnelIfTable.
