Operation Manual – Mirroring
H3C S7500 Series Ethernet Switches
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.
Be sure not to configure a port used to connect the intermediate and destination
switches as the mirroring source port. Otherwise traffic disorder may occur in the
network.
