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. Local port mirroring configuration task list Tasks at a glance 1. (Required.) Creating a local mirroring group 2. (Required.)Configuring source ports for the local mirroring group 3. (Required.) Configuring the monitor port for the local mirroring group Creating a local mirroring group Step 1. Enter system view. 2. Create a local mirroring group. Command system-view mirroring-group group-id local 106 Remarks N/A By default, no local mirroring group exists.
