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.

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.
Ports to Mirror:

Apply:
Sets specified values to the system.
Cancel:
Discards all changes and restores current values.
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.
