NOTE:
Incorrect recovery can occur when loop detection frames are discarded to reduce the load. To avoid
this, use the shutdown action, or manually remove the loop.

Enabling loop detection
You can enable loop detection globally or on a per-port basis. The global configuration applies to all
ports in the specified VLANs. The per-port configuration applies to the individual port only when the
port belongs to the specified VLANs. Per-port configurations take precedence over global
configurations.
As a best practice, do not enable loop detection on TRILL ports, because TRILL networks prevent
loops from being generated. For information more about TRILL, see
TRILL Configuration Guide

Setting the loop protection action
You can configure the loop protection action globally or on a per-port basis. The global setting
applies to all ports. The per-port setting applies to the individual ports. The per-port setting takes
precedence over the global setting.
