Use the Appliance Settings: Port Mirroring page to configure port mirroring on the managed Network Security appliance. Two types of port mirroring are supported—port mirroring for all traffic types (including SSL encrypted traffic) and SSL decryption mirroring. You can configure and enable each feature separately.
To configure port mirroring:
Click Settings and then select Appliance Settings.
Click Port Mirroring in the sidebar.
(Optional) Use the controls at the top of the page to define the scope of the changes.
