The source device copies packets received on the source port to the egress port. The egress port forwards
the packets to the intermediate devices, which then broadcast the packets in the remote probe VLAN and
transmit the packets to the destination device. Upon receiving the mirrored packets, the destination
device checks whether their VLAN IDs are the same as the remote probe VLAN ID. If yes, the device
forwards them to the data monitoring device through the monitor port.
To make sure the source device and the destination device can communicate at Layer 2 through the
remote probe VLAN, assign the intermediate devices' ports in the direction to the source and destination
devices to the remote probe VLAN.

Configuring local port mirroring

Local port mirroring takes effect only when the source ports, and the monitor port are configured.
