4.4.5 Port Mirror
Configure port Mirroring on this page. This function provides monitoring 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.
