Port Mirroring
You can mirror traffic from any source port to a target port for real-time analysis. You
can then attach a logic analyzer or RMON probe to the target port and study the
traffic crossing the source port in a completely unobtrusive manner.

Ports to Mirror
Select the ports that you want to mirror from this section of the page. A port will be
mirrored when the “Mirroring Enabled” check-box is checked.
• Port to Mirror to – The port that will “duplicate” or “mirror” the traffic on the source
port. Only incoming packets can be mirrored. Packets will be dropped when the
available egress bandwidth is less than ingress bandwidth.
Note:
If the total ingress bandwidth exceeds the mirror port’s egress bandwidth, packets
will eventually be dropped on ingress to the switch, which means they will not
reach the mirror port or their intended destination port. Input rate-limiting in
conjunction with port flow-control should be used to ensure that the total ingress
bandwidth never exceeds the egress bandwidth.
