Port Mirroring
You can mirror (copy) incoming and outgoing packets on multiple source
ports to a single target port for real-time analysis. You can then attach a
network analyzer or RMON probe to the target port and study the traffic
crossing the source ports in a completely unobtrusive manner.
Field Attributes
Port to Mirror to
• Port to Mirror to – The port that will be use to “mirror” another
port’s incoming and outgoing packets. Data packets will be dropped
when data coming in is greater than the port can handle.
N o t e
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.
Ports to Mirror
• Mirroring Enabled – A port whose traffic will be monitored. If
enabled, the incoming and outgoing packets on this port will be
mirrored. (Default: Disabled)
