Operation Manual – Mirroring
H3C S7500 Series Ethernet Switches
Note:
If you want to mirror the tagged packets, you need to configure VLAN VPN on the
reflector port.
For the reflector port can not forward traffic as a normal port does, you are
recommended to configure the port that is not in use to be the reflector port and not
to perform other configurations on this port.
III. Configuring the intermediate switch
The configuration of remote traffic mirroring on the intermediate switch is the same as
that of remote port mirroring on the intermediate switch. Refer to
port mirroring on the intermediate
IV. Configuring the destination switch
The configuration of remote traffic mirroring on the destination switch is the same as
that of remote port mirroring on the destination switch. Refer to
mirroring on the destination
V. Configuration example
1) Network requirements:
Switch A is connected to the data detect device through GigabitEthernet 2/0/2.
GigabitEthernet 2/0/1, the Trunk port of Switch A, is connected to GigabitEthernet
2/0/1, the Trunk port of Switch B.
GigabitEthernet 2/0/2, the Trunk port of Switch B, is connected to GigabitEthernet
2/0/1, the Trunk port of Switch C.
GigabitEthernet 2/0/2, the port of Switch C, is connected to the 10.1.1.1/24
network segment.
Use the remote traffic mirroring function to mirror the packets from the 10.1.1.1/24
network segment to GigabitEthernet 2/0/2, the port of Switch A, so that the data detect
device can monitor the traffic:
Define VLAN10 as remote-probe VLAN.
Define Switch A as the destination switch; configure GigabitEthernet 2/0/2, the
port that is connected to the data detect device, as the destination port for remote
mirroring. Set GigabitEthernet 2/0/2 to an Access port, with STP and LACP
functions disabled.
Define Switch B as the intermediate switch.
Define Switch C as the source switch, GigabitEthernet 2/0/3 as the reflector port.
Set GigabitEthernet 2/0/3 to an Access port, with STP and LACP disabled.
Configure the traffic mirroring function on GigabitEthernet 2/0/2.
