A disabled port cannot transmit or receive packets (the PoE function is not affected). Disabling all ports of a switch will 
make the switch unmanageable. Therefore, exercise caution when disabling ports. 
3.4.2  Port Mirroring 
Port mirroring forwards input/output packets of one or more source port to the destination port to monitor the network. 
 
 
Destination mirroring ports on RG-ES205C-P, RG-ES205GC-P, RG-ES209C-P, and RG-ES209GC-P can only capture 
packets. They cannot transmit data to the switch.
