Table 2-3  Port Mirroring Parameters 
The source port is also called the monitored port. Packets on the source port 
will be mirrored to the mirror port for network analysis or troubleshooting. 
Users can select multiple source ports. Packets on these ports will be mirrored 
to one mirror port. 
Direction of the data traffic monitored on the source port: 
⚫  Bi-directions (input & output): All packets on the source port, including the 
received packets and the transmitted packets, will be mirrored to the mirror 
port. 
⚫  Input: The packets received by the source port will be mirrored to the mirror 
port. 
⚫  Output: The packets transmitted from the sourced port will be mirrored to 
the mirror port. 
The mirror port is also called the monitoring port. The mirror port is connected 
with a monitoring device, and it transmits packets on the source port to the 
monitoring device. 
 
2.4   Port Isolation 
Choose Switch Settings > Port Isolation. 
Port isolation is used for isolating layer-2 packets. When port isolation is enabled, the downlink ports are isolated 
from each other but can communicate with uplink ports. 
Port isolation is disabled by default. Toggle the switch to On to enable port isolation.
