The following subsections describe how local port mirroring, Layer 2 remote port mirroring, and Layer 3 

remote port mirroring are implemented.  

Local port mirroring is implemented through a local mirroring group. In local port mirroring, packets 

passing through a port (mirroring port) are mirrored to the monitor port located on the same device. 

Figure 1-1 Local port mirroring implementation 

 

 

As shown in 

, packets of the mirroring port are mirrored to the monitor port for the data 

monitoring device to analyze.  

 

The mirroring ports and the monitor port in a local mirroring group can be located on different LPUs of a 

same device. 

 

Layer 2 remote port mirroring is implemented through the cooperation between a remote source 

mirroring group and a remote destination mirroring group as shown in 

.

On the network shown in 

, a remote source mirroring group is created on the source device 

and a remote destination mirroring group is created on the destination device. The source device
