2. The device automatically sets the port to the forwarding state after the detection timer
configured by using the shutdown-interval command expires. For more information about the
shutdown-interval command, see Fundamentals Command Reference.
3. The device shuts down the port again if a loop is still detected on the port when the detection
timer expires.
This process is repeated until the loop is removed.
NOTE:
Incorrect recovery can occur when loop detection frames are discarded to reduce the load. To avoid
this problem, 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.
