disables the port from learning MAC addresses, and blocks inbound traffic on
the port.
•

performs no action on the port.
•
No-learning—When a loop is detected on a port, the device generates a log
and disables the port from learning MAC addresses.
•
Shutdown—When a loop is detected on a port, the device generates a log and
shuts down the port to disable it from receiving and sending any frames.
