Tips:
If both the mirrored port and the mirroring port are the LAN ports, these two LAN ports should be in the same Port VLAN. For example, if port 3 (the mirroring port) and port 4 (the mirrored port) are the LAN ports, the Port Mirror function can take effect only when port 3 and port 4 are in the same Port VLAN.
