    Hi there, so that depends on the interface itself and whether it has interface index ID persistence. Interfaces that persist their index ID should remain the same prior to a reboot or status change of the interface, but they would be discovered as a new interface instance if they don't persist the interface index.
    I would recommend looking into whether the interfaces in question support index ID persistence, and enable it if possible so the interface instance remains the same after a reboot.
    If this behavior occurs on a monitored interface in your LogicMonitor portal, I would recommend reaching out to support to look into the specific case in more detail
