Figure 6- 13. Setup Port Mirroring window
The target port is where information will be duplicated and sent
for capture and network analysis. This is the port where a
network analyzer would be attached to capture packets
duplicated from the source port.
It should be noted that a faster port (a 1000 Mbps Gigabit
Ethernet port, for example) should not be mirrored to a slower
port (one of the 48 100 Mbps Fast Ethernet ports), because
many packets will be dropped.
The following fields can be set:
