Show the status of the port and you'll see it's down (monitoring).

Configuring SPAN and RSPAN (Catalyst 3550 scg)

"VLAN and trunkingYou can modify VLAN membership or trunk settings for
source, destination, or reflector ports at any time. However, changes in
VLAN membership or trunk settings for a destination or reflector port do
not take effect until you disable the SPAN or RSPAN session. Changes in
VLAN membership or trunk settings for a source port immediately take
effect, and the respective SPAN sessions automatically adjust accordingly."
