4.4.2 Port Mirroring
On this page, port mirroring provides monitoring network traffic that forwards a copy of each incoming or outgoing packet from
one port of a Managed PoE+ 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 PoE+ 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 4-4-3: Port Mirroring 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).
