Description: Broadcom FastPath MIB for IPv6 loopback interface configuration and address management on FastPath networking 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 FASTPATH-IPV6-LOOPBACK-MIB?
This Broadcom FASTPATH private MIB manages IPv6 loopback interface configuration on FASTPATH-based switches, letting an administrator assign one or more IPv6 addresses to a virtual loopback interface used as a stable device identifier independent of any physical port's state. As a narrowly-scoped configuration MIB, it exposes loopback interface creation/enable state and IPv6 address assignment rather than a broad set of runtime counters. Its monitoring relevance is limited but real from a software-configuration standpoint — confirming the loopback interface is up and correctly holding its configured IPv6 address is important because many management and routing protocol processes (e.g., BGP, OSPFv3 router IDs) rely on the loopback staying reachable regardless of physical interface flaps. It has no dependency on an external IETF loopback MIB, being a vendor-private extension layered on the standard IF-MIB interface model. It is deployed on FASTPATH-based switches/routers wherever a stable IPv6 management or routing-protocol source address is needed. Engineers can download the FASTPATH-IPV6-LOOPBACK-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in FASTPATH-IPV6-LOOPBACK-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
- FASTPATH-based Ethernet switch/router (multiple OEM brands)
Monitoring Examples
No sample object names were available for this MIB beyond its general purpose, so a concrete polling example cannot be grounded in real names; based on its description, an admin would be expected to poll a loopback-interface table for its configured IPv6 address(es) and administrative/operational state to confirm the loopback remains correctly configured and reachable for management or routing-protocol use.
What Can Be Monitored
- IPv6 loopback interface configuration state
- assigned IPv6 address(es) on loopback
