Port mirroring configuration
Introduction to port mirroring
Port mirroring is the process of copying the packets passing through a port (called a mirroring port) to another port (called the monitor port) connected with a monitoring device for packet analysis.
You can mirror inbound, outbound, or bidirectional traffic on a port as needed.
Implementing port mirroring
Port mirroring is implemented through local port mirroring groups. The following subsections describe how local port mirroring is implemented.
Local port mirroring
In local port mirroring, all packets (including protocol and data packets) passing through a port can be mirrored. Local port mirroring is implemented through a local mirroring group.
As shown in a, packets on the mirroring port are mirrored to the monitor port for the data monitoring device to analyze.
