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):

local
Required
By default, no mirroring group
exists on a device.
Configuring Mirroring Ports for a Local Mirroring Group
On the source device, configure the ports you want to monitor as the mirroring ports; on the destination
device, configure the physical port corresponding to the tunnel interface as the mirroring port.
You can configure a list of mirroring ports for a mirroring group at a time in system view, or assign only
the current port to it as a mirroring port in interface view. To assign multiple ports to the mirroring group
as mirroring ports in interface view, repeat the step.
