4.3.4 Port Mirroring
Configure port Mirroring on this page. This function provides 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 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 4-3-8 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).
Mirror Port Configuration
The Port Mirror Configuration screens in Figure 4-3-9 & Figure 4-3-10 appear.
