When a switch acts as a remote port mirroring destination 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
mirroring destination port.
V. Configuration example
1) Network requirements:
z Switch A is connected to the data detect device via GigabitEthernet 2/0/2.
z GigabitEthernet 2/0/1, the Trunk port of Switch A, is connected to GigabitEthernet
2/0/1, the Trunk port of Switch B.
z GigabitEthernet 2/0/2, the Trunk port of Switch B, is connected to GigabitEthernet
2/0/1, the Trunk port of Switch C.
z GigabitEthernet 2/0/2, the port of Switch C, is connected to PC 1.
The purpose is to monitor and analyze the packets sent to PC 1 via the data detect
device.
To meet the requirement above by using the remote port mirroring function, perform the
following configuration:
z Define VLAN 10 as remote-probe VLAN.
