Port Mirroring Configuration

In port mirroring, packets passing through mirrored ports are copied and then sent to specified observing ports for analysis and monitoring.

NOTE:

If N:1 mirroring or multiple 1:1 mirroring configurations are implemented, mirrored packets may be lost.
The physical port cannot be configured as an observing port and mirrored port simultaneously.
If both port mirroring and traffic mirroring are configured simultaneously for the same packets, port mirroring takes effect

Choose Configuration > Advanced Services > Mirroring to open the Mirroring page.
Click the Port Mirroring Configuration tab to open the Port Mirroring Configuration page.
Click Select following Select observing port, Inbound mirrored port, and Outbound mirrored port in sequence to open the Select page.
NOTE:
If you do not configure ports in the preceding sequence, the selected port is automatically configured as the first port that is not configured. For example, if Outbound mirrored port is configured but Select observing port and Inbound mirrored port are not configured, the selected Outbound mirrored port is automatically configured as Select observing port.
Select the icons of the interfaces to be configured as an observing port, inbound mirrored port, or outbound mirrored port, and click OK.
Click Apply. In the dialog box that is displayed, click OK to complete the configuration.
Click Clear Mirroring Configuration to clear the previous port mirroring configuration.
