Configuring Layer 3 Remote Port Mirroring
Layer 3 Remote Port Mirroring Configuration Task List
To configure Layer 3 remote port mirroring, you need to create a local port mirroring group on the
source device as well as on the destination device, and configure mirroring port and the monitor port
for each mirroring group. The source and destination devices are connected by a tunnel.
z On the source device, you need to configure the port you want to monitor as the mirroring port,
and configure the tunnel interface as the monitor port.
z On the destination device, you need to configure the physical port corresponding to the tunnel
interface as the mirroring 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:

Generally, a port can belong to only one mirroring group. On an SD or EB series LPU, however, a port
can be assigned to two mirroring groups as a mirroring port.
Configuration Prerequisites
Before configuring Layer 3 remote port mirroring, make sure that you have created a GRE tunnel that
connects 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):
