Mirror Configuration 

Mirror Configuration is to monitor the traffic of the network. For example, we assume that 
Port A and Port B are

 

Monitoring Port and Monitored Port respectively, thus, the traffic 

received by Port B will be copied to Port A for monitoring.

   

Note: When configuring the mirror function, you should avoid setting a port to be a 
sniffer port and aggregated port at the same time. It will cause something wrong. 

Mode: 

Used for the activation or de-activation of Port Mirror 
function. Default is Disable. 

Monitoring Port: 

Set up the port for monitoring. Valid port is Port 1~8 and 
default is   
Port 1. 

Monitored Port: 

Set up the port for being monitored. Just tick the check box 
(;) beside the port x and valid port is Port 1~8.
