In this case, allthe ports in the VLAN can receive the mirrored packets. Even if the VLAN does not exist, you canpre-define the action of mirroring traffic to the VLAN. After the VLAN is created and some ports jointhe VLAN, the action of mirroring traffic to the VLAN takes effect automatically.On the S5810 series Ethernet switches, traffic can only be mirrored to ports and to CPU.Configuring Traffic MirroringTo configure traffic mirroring, you must enter the view of an existing traffic behavior.In a traffic behavior, the action of mirroring traffic to an interface and the action of mirroring traffic to aCPU are mutually exclusive.
