This object controls whether the bridge runs its early loop detection algorithm, which restarts the Spanning Tree Protocol when a packet is received on one interface from a source MAC previously learned on a different interface, defaulting to disabled. An admin enables this to get faster loop detection than STP convergence alone would provide, at the cost of extra STP restarts triggered by MAC address movement. For example, enabling this on a network prone to accidental cabling loops would cause STP to restart promptly whenever the early-loop condition is detected.
