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.

set to “manual,” the interface can be re-enabled using the spanning-
tree loopback-detection release command.
