Reflector Port:

The reflector port is the mechanism that copies packets onto an RSPAN VLAN. The reflector port forwards only the traffic from the RSPAN source session with which it is affiliated. Any device connected to a port set as a reflector port loses connectivity until the RSPAN source session is disabled.

n-isl is a reference to Cisco Inter Switch Link trunking protocol.

My guess is you wont understand anything I wrote until you do some reading of the basics.
