Description: Broadcom FastPath MIB for IPv6 transition tunneling (6in4, ISATAP) configuration and status on FastPath-based 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 FASTPATH-IPV6-TUNNEL-MIB?

FASTPATH-IPV6-TUNNEL-MIB is a Broadcom private MIB for switches/routers running the FastPath switching software stack, providing management of IPv6-transition tunnels such as 6in4 and ISATAP configured on the device. It exposes tunnel configuration objects (endpoint addressing, tunnel type/mode) and status information indicating whether each configured tunnel is operationally up and passing traffic. Its monitoring value is primarily software/configuration-state oriented, confirming a given IPv6-over-IPv4 tunnel is correctly configured and up, which matters when IPv6 connectivity is being transitioned over legacy IPv4 infrastructure. It relies on the standard IF-MIB for interface indexing of tunnel interfaces and on general IPv6 addressing conventions. It is deployed on Broadcom FastPath-based Ethernet switches/routers (used by multiple OEM vendors) in networks undergoing IPv4-to-IPv6 transition. Engineers can download the FASTPATH-IPV6-TUNNEL-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in FASTPATH-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.

Monitoring Examples

No specific object names were captured for this MIB, so exact polling targets cannot be confirmed, but consistent with its stated purpose an admin would expect to poll per-tunnel configuration and operational-status objects to confirm a configured 6in4 or ISATAP tunnel interface is up and its endpoints match the intended IPv4 addresses. A tunnel reporting a down or misconfigured status would explain a loss of IPv6 reachability across that transition path.

What Can Be Monitored

IPv6 tunnel configuration (type/endpoints)
tunnel operational status

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.
