If I understand you correctly, no you do not need to enter "sw access
vlan 44", the reflector port is used to loop the traffic your monitoring
from your source port/vlan, out the interface, back in and onto the
remote span vlan. Configuring the "reflector port" effectively disables
it just as if were a local port used in a local span session. Unless I'm
not catching what your throwing.
