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.  

 

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): 

Enter system view 

— 

Create a local mirroring group 

mirroring-group group-id 
local 

Required 

By default, no mirroring group 
exists on a device.  

 

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.  

Follow these steps to configure mirroring ports for a local mirroring group in system view: 

Enter system view 

— 

Configure mirroring ports for a 
local mirroring group 

mirroring-group group-id 
mirroring-port 
mirroring-port-list { both | 
inbound | outbound } 

Required 

By default, no mirroring port is 
configured for a mirroring 
group.
