You can configure the monitor port for a mirroring group in system view, or assign the current port to a 

mirroring group as the monitor port in interface view. The two modes lead to the same result.  

Follow these steps to configure the monitor port of a local mirroring group in system view: 

Enter system view 

— 

Configure the monitor port 

mirroring-group group-id 
monitor-port monitor-port-id 

Required 

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

 

Follow these steps to configure the monitor port of a local mirroring group in interface view: 

Enter system view 

— 

Enter interface view 

interface interface-type 
interface-number 

— 

Configure the current port as 
the monitor port 

[ mirroring-group group-id ] 
monitor-port 

Required 

By default, a port does not 
serve as the monitor port for 
any mirroring group.  

 

z 

A mirroring group contains only one monitor port.  

z 

To ensure that the port mirroring function works properly, do not enable STP, MSTP, or RSTP on 

the monitor port.  

z 

You are recommended to use a monitor port only for port mirroring. This is to ensure that the data 

monitoring device receives and analyzes only the mirrored traffic rather than a mix of mirrored 

traffic and normally forwarded traffic. 

z 

A port connected to an RRPP ring cannot be configured as the monitor port of a port mirroring 

group.
