TCP 8681 is missing in Installation guide for NFA and CAPC, make sure you open a port on firewall - 8681 Enables synchronization with CA Network Flow Analysis (CAPC and NFA device data).
Port 8681 is required for CAPC to retrieve live data from NFA. Port 80 will sync with NFA devices and Interfaces but it will not populate data.
