Traffic Mirroring Configuration Examples

7.1 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 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.

On S5500-EI series Ethernet switches, traffic can only be mirrored to ports and to CPU.
