If Port Loopback Detection is not enabled and a port receives it’s own
BPDU, then the port will drop the loopback BPDU according to IEEE
Standard 802.1W-2001 9.3.4 (Note 1).
◆
Port Loopback Detection will not be active if Spanning Tree is disabled
on the switch.

If an interface is shut down by this command, and the release mode is
set to “auto” with the
spanning-tree loopback-detection release-mode
command, the selected interface will be automatically enabled when
the shutdown interval has expired.
◆
If an interface is shut down by this command, and the release mode is
set to “manual,” the interface can be re-enabled using the
tree loopback-detection release
command.
