I believe this is also in the archives...  But the short answer is that the
3550 DOES need to have one the 3560 does not. 

The up/up part is irrelevant because you're stealing the ASICs for
processing the frames.  So even if someone plugs into the port, they can't
get anywhere....

The 3560's ASICs are shared by the chassis (not port-specific) so the
reflector isn't necessary.

Subject: RSPAN on 3560

Hi group,
when i was looking up configuration guide about RSPAN, i compared the
configurations on 3550 and 3560.
There is a small difference:
 On 3550: monitor session session_number destination remote vlan vlan_id  on
3560: monitor session session_number destination remote vlan vlan_id
reflector-port interface 

Is it no need to configure refector-port on 3550?

One more question: what are the requirements of reflector-port when
configuring on 3550.

It must be "up up" and "access mode"?

thank you for your response.
