Description: Manages IPv6 tunnel interfaces for transition mechanisms such as 6in4 and ISATAP on Dell DNOS devices.

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 DNOS-IPV6-TUNNEL-MIB?

DNOS-IPV6-TUNNEL-MIB manages IPv6 tunnel interfaces on Dell DNOS devices, supporting IPv6 transition mechanisms such as 6in4 and ISATAP tunneling. It exposes configuration objects for defining tunnel endpoints, encapsulation mode, and tunnel interface parameters, functioning as configuration/state data for the tunneling feature rather than hardware health data. In a monitoring context it is useful mainly for confirming tunnel interface operational status (up/down) as part of software/network-service status tracking during IPv4-to-IPv6 migrations. It is a Dell Networking private MIB with likely reliance on the standard IF-MIB for representing tunnel interfaces as generic network interfaces. It is deployed on Dell DNOS routers/switches operating in mixed IPv4/IPv6 environments that require tunneling for IPv6 connectivity, and administrators can download the DNOS-IPV6-TUNNEL-MIB file to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DNOS-IPV6-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

Dell DNOS router/switch

Monitoring Examples

No sample_objects were supplied; based on the description an admin would poll a tunnel configuration/status table (a plausible ipv6TunnelTable) to verify a configured 6in4 or ISATAP tunnel's operational state and endpoint addresses. A tunnel interface reporting down when it should be up would indicate a misconfigured endpoint or underlying IPv4 reachability issue. This scenario is inferred from the module's stated purpose since no object names were provided.

What Can Be Monitored

tunnel interface configuration
tunnel operational status
tunnel endpoint addresses

I32 agentTunnelID	1.3.6.1.4.1.674.10895.5000.2.6132.1.1.27.1.1.1.1	Integer32	not-accessible	The tunnel ID is associated with Internal Interface number which is generated when we create a tunnel, and is used to configure the tunnel.
I32 agentTunnelIfIndex	1.3.6.1.4.1.674.10895.5000.2.6132.1.1.27.1.1.1.2	Integer32	read-only	The external interface of the tunnel is associted with internal interface. The tunnel ID associated with Internal Interface number is generated when we create a tunnel, which is used to configure the tunnel.
INT agentTunnelMode	1.3.6.1.4.1.674.10895.5000.2.6132.1.1.27.1.1.1.3	INTEGER	read-create	Specifies the type of Tunnel either undefined, 6over4 or 6to4. The default value is undefined. It supports 6over4 which supports an assigned IPV6 address, an IPV4 address is not allowed. For this mode, the tunnel source and tunnel destination must be IPV4 address. For 6to4 tunnel, the tunnel source must be IPv4 address. Tunnel destination should not be set. The first 48-bits of the IPv4 address assigned to the 6to4 tunnel should be of the format 2002:sourceIpv4address.
