4.4.5 Port Mirror
Configure port mirroring on this page. This function provides to monitor 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 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.
Figure 4-4-5: Port Mirror Application
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).
