EdgeSwitch-LOOPBACK-MIB

Description: Ubiquiti EdgeSwitch loopback MIB for configuring and monitoring logical loopback interfaces and their IP addresses.

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.

The EdgeSwitch-LOOPBACK-MIB is a Ubiquiti private MIB, part of the FastPath-based EdgeSwitch software, for configuring and monitoring logical loopback interfaces. It exposes objects covering interface creation/deletion, administrative and operational state, and the IP address bound to each loopback interface. Its monitoring value is in confirming that a loopback interface used for stable management access or routing (e.g., a router-id anchor) remains up and correctly addressed, which is effectively a software/interface-state health check rather than physical hardware monitoring. It builds on the same ifIndex-based interface model used throughout standard IF-MIB implementations. It is used in Layer 3-routed EdgeSwitch deployments that need a persistent management or routing-protocol source address independent of any single physical port. Engineers can download the EdgeSwitch-LOOPBACK-MIB file directly to load it into their MIB browser.

An admin would poll a loopback interface table entry for admin/operational status and its assigned IP address to confirm loopback0 stays up and its address unchanged after a configuration reload; a loopback interface unexpectedly reporting down, or its IP reverting to a default, would reveal that a config save/reload discarded the intended settings.
