6.18 Mirroring
You can mirror traffic from any source port to a target port for real-time analysis. You can then attach a logic analyzer or RMON
probe to the target port and study the traffic crossing the source port in a completely unobtrusive manner.
Mirror Configuration monitors the network traffic. For example, if Port A and Port B are monitoring port and monitored port
respectively, the traffic received by Port B will be copied to Port A for monitoring.
Web Interface
To configure the mirror in the Web interface:
1. Click “Configuration,” “Mirroring.”
2. Scroll to select the port to mirror.
3. Scroll to disabled, enable, TX Only and RX Only to set the port mirror mode.
4. Click on the “Save” button to save the setting.
5. To cancel the setting, click the “Reset” button. It will revert to previously saved values.
