Port Mirroring

Click the

link and then the
Target Port Selection
link:
Figure 6-54. Target Port Selection
The target port is the port 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.
Up to 25 entries can be made to the port mirroring table, but 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 24 100 Mbps Fast Ethernet port), because
many packets will be dropped.
