About Firepower Threat Defense with FMC
The FTD provides next-generation firewall services, including stateful firewalling, routing, VPN, Next-Generation Intrusion Prevention System (NGIPS), Application Visibility and Control (AVC), URL filtering, and Advanced Malware Protection (AMP).
You can manage the FTD using the Firepower Management Center (FMC), a full-featured, multidevice manager on a separate server.
The FTD registers and communicates with the FMC on the Management interface that you allocated to the FTD logical device.
For troubleshooting purposes, you can access the FTD CLI using SSH on the Management interface, or you can connect to the FTD from the FXOS CLI.
