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 could be used to ensure that the total ingress
bandwidth never exceeds the egress bandwidth.
