I figured I didn't answer your question...sorry...I have never done it
this way. I always use an unused port for the reflector...Gotta burn a
port. It doesn't make sense to do it that way for me...and I know it's
the logic and understanding we are looking for. In short...I don't
know...

Thanks, but it didn't make things clear for me... sorry.
Let me put it tis way.
If RSPAN VLAN is 444, and reflector port is fa 0/21 - do I have to do
in fa 0/21
sw acc vlan 444
Does this reflector port need to be in "connected" status?
Very practical questions, cause you don't have a way to test this config
on real lab so you have to know what port to pick as a reflector port
and how this port should be configured. This part is missing on DocCD
section regarding RSPAN, ... or I cannot read it.
I used a lot of SPAN sessions within one switch for my work, but never
RSPAN and in my current lab there is only one 3550 so cannot lab it up.

1. Any access ports configured into an RSPAN VLAN shall become
inactive and remain in that state until either the ports are configured
into another VLAN or the VLAN is no longer an RSPAN VLAN.
2. Learning is disabled in RSPAN VLANs. This ensures that traffic
is flooded to all the trunk ports in the VLAN.
3. Trunk ports carry RSPAN VLAN traffic like that of any other
VLAN. VTP pruning supports pruning of RSPAN VLAN traffic on trunk ports.
4. STP is enabled for all ports in the RSPAN VLAN, to support link
redundancy while avoiding loops.

is that relevant if the reflector port belongs to that special RSPAN
VLAN?
