Traffic Mirroring Configuration Examples 

Traffic mirroring is implemented by a QoS policy, which defines certain match criteria to match the 

packets to be mirrored and defines the action of mirroring such packets to the specified destination.  

Depending on different types of mirroring destinations, there are two types of traffic mirroring: 

z 

Mirroring to port: The desired traffic on a source port is replicated and sent to a destination port. 

z 

Mirroring to CPU: The desired traffic on a source port is replicated and sent to the CPU on the LPU 

of the port for further analysis. 

Remote traffic mirroring combines traffic mirroring with remote port mirroring to use a remote mirroring 

group to mirror local packets matching the specified criteria to the specified destination port on a remote 

device.  

Remote traffic mirroring is implemented as follows: configure traffic mirroring on the local device to 

mirror packets matching certain criteria to an egress port; configure a remote source mirroring group on 

the local device and specify the destination port for traffic mirroring as the egress port, so that packets 

sent to the destination port by traffic mirroring can be mirrored to the remote device by remote port 

mirroring. 

Follow these steps to configure traffic mirroring: 

Enter system view 

— 

Create a class  and enter the 
corresponding class view 

traffic classifier classifier-name 
[ operator { and | or } ] 

Required 

By default, the and keyword 
is specified. That is, the 
relation between the rules in 
the class view is logic AND. 
This operation leads you to 
class view.
