Mike,
In 3550, to make RSPAN works, yes!! you need to configure reflector-port.
Basically, the traffic that have captured on source switch will be copied
through RSPAN vlan through reflector port. And the remote switch that have
been configured with destination will see this traffic from RSPAN vlan
through the trunk. In some platform like 2960, we don't need to use
reflector-port.
HTH,
Montiean
