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 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.
