I don't know if you'll ever see anything explicitly stating to use a "unused
port" as the reflector port, but the doc does supply this:
.When you configure a switch port as a reflector port, it is no longer a
normal switch port; only looped-back traffic passes through the reflector
port.
http://www.cisco.com/univercd/cc/td/doc/product/lan/c3550/12225see/scg/swspan.htm#wp1401252
So, from this, you can infer that your reflector port can't be a port that
is being used for 'normal port duties' (whatever that may constitute).
IOW - don't assign a reflector-port to a port that is being used for
something else.
Consider the ambiguity as job-security when you become a CCIE!
HTH,
Sean

Thank you all for the responses.
Now is this some thing obvious in the docs ? I do see
that it tell not to use trunk port but it never says
to use a "un-used port" for reflector port in the doc,
unless i have overlooked it ?
Thank you,
