Port mirror
Configure port mirroring on the Mirror & RMirror Configuration Table page. This function
provides the monitoring of network traffic that forwards a copy of each incoming or
outgoing packet from one port of a network switch to another port where the packet can
be studied. It enables the manager to keep close track of switch performance and alter
it if necessary.
• To debug network problems, selected traffic can be copied, or mirrored, to a mirror
port where a frame analyzer can be attached to analyze the frame flow.
• The industrial managed switch can unobtrusively mirror traffic from any port to a
monitor port. You can then attach a protocol analyzer or RMON probe to this port to
perform traffic analysis and verify connection integrity.
The traffic to be copied to the mirror port is selected as follows:
• All frames received on a given port (also known as ingress or source mirroring).
• All frames transmitted on a given port (also known as egress or destination
mirroring).
