Configuring Layer 3 remote port mirroring

Layer 3 remote port mirroring configuration task list

To configure Layer 3 remote port mirroring, you must create a local mirroring group on the source device
as well as on the destination device, and configure source ports/CPUs and the monitor port for each
mirroring group. The source and destination devices are connected by a tunnel. If an intermediate device
exists, configure a unicast routing protocol on the intermediate device to make sure that the source device
can reach the destination device at Layer 3.
On the source device, you must configure the ports/CPUs you want to monitor as the source
•
ports/CPUs, and configure the tunnel interface as the monitor port.
On the destination device, you must configure the physical port corresponding to the tunnel
•
interface as the source port, and configure the port that connects the data monitoring device as the
monitor port.
Complete these tasks to configure Layer 3 remote port mirroring:

Configuration prerequisites

Create a tunnel interface and a GRE tunnel that connect the source and destination devices.

Configuring local mirroring groups

Configure a local mirroring group on the source device and on the destination device separately.
Follow these steps to create a local mirroring group (on the source or destination device):
