To capture packets that are dropped by Cisco Secure Firewall Threat Defense (FTD) and troubleshoot the issue of traffic from the inside network to a webserver not getting through, the administrator should use the command to capture packets dropped by the accelerated security path (ASP) engine. The correct command is:

capture CAP type asp-drop all headers-only

This command captures all packets dropped by the ASP engine, which includes packets that are being blocked by access control policies, NAT issues, or other security checks.

Steps:

Access the FTD CLI.

Run the commandcapture CAP type asp-drop all headers-onlyto capture dropped packets.

Analyze the captured data to identify the cause of the drops.

This command provides detailed information on why packets are being dropped, helping the administrator resolve the issue.
