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 is used to monitor the traffic of the network. For example, we assume that Port A and Port
B are Monitoring Port and Monitored Port respectively, so the traffic received by Port B will be copied to Port A
for monitoring.
To configure the Port Mirror function in the web UI:
1.
Click Diagnostics and Mirroring.
2.
Select the Monitor Destination Port (Mirror Port).
3.
Select mode (disabled, enable, TX Only and RX only) for each monitored port.
4.
Click the Apply button to save the settings.
5.
To cancel the settings click the Reset button to revert to previously saved values.
