- Page 10 Operation Manual – Mirroring H3C S7500 Series Ethernet Switches Chapter 1 Mirroring Configuration Note: To mirror tagged packets, you need to configure VLAN VPN on the reflector port. The reflector port cannot forward traffics as a normal port. Therefore, it is recommended that you use a idle and in-down-state port as the reflector port, and be careful to not add other settings on this port.
- Page 11 Operation Manual – Mirroring H3C S7500 Series Ethernet Switches Chapter 1 Mirroring Configuration Note: When a switch acts as a remote port mirroring intermediate switch, to realize the data mirroring successfully, you are recommended to configure redirection on the inbound interface and redirect all the packets in the remote-probe VLAN to the corresponding outbound interface.
