9.1 Overview
Traffic mirroring is to replicate the specified packets to the specified destination. It is
generally used for testing and troubleshooting the network. .
Depending on different types of mirroring destinations, there are three types of traffic
mirroring:
Mirroring to port: The desired traffic on a mirrored port is replicated and sent to a
destination port (that is, a mirroring port).
Mirroring to CPU: The desired traffic on a mirrored port is replicated and sent to
the CPU on the board of the port for further analysis.
Mirroring to VLAN: The desired traffic on a mirrored port is replicated and sent to a
VLAN, where the traffic is broadcast and all the ports (if available) in the VLAN will
receive the traffic. If the destination VLAN does not exist, you can still configure
the function, and the function will automatically take effect after the VLAN is
created and a port is added to it.
9.2 Configuring Traffic Mirroring
To configure traffic mirroring, you must enter the view of an existing traffic behavior.
Note:
In a traffic behavior, the action of mirroring traffic to a port, and the action of mirroring
traffic to a CPU are mutually exclusive.
