Once the loop is removed, the interface is re-enabled, the fault clears, and traffic resumes after the 10-minute time-out.
Change the TIMEOUT values to 0. With the interface and BPDU Cop enabled, this change is immediate.

SET STP INTERFACE=0.23 TIMEOUT=0
If a loop occurs, BPDU Cop disables the interface and it remains disabled.
