Capture interfaces monitor traffic that external devices have duplicated for inspection to the Single Firewall.
You can have as many capture interfaces as there are available physical ports on the Single Firewall (there are no license restrictions regarding this interface type).
External equipment must be set up to mirror traffic to the capture interface. You can connect a capture interface to an external switch SPAN port or a network TAP to capture traffic.
