Clear an External Switching Command on a Path Protection Span
Note If the ports terminating a span are configured as revertive, clearing a Force or Manual switch to protect
moves traffic back to the working port. If ports are not configured as nonrevertive, clearing a Force
switch to protect does not move traffic back.
