Cisco FPR2120-ASA-K9 | Firepower 2120 Firewall, 6 Gbps, 12x 1G RJ45, 4x 1G SFP

Q: What software image does the FPR2120-ASA-K9 run?
A: This model runs the Cisco Adaptive Security Appliance (ASA) software image. The Firepower 2120 platform can alternatively support Cisco Firepower Threat Defense software, but the -ASA-K9 SKU is pre-configured for ASA deployment.

Q: What is the difference between firewall throughput and VPN throughput?
A: The FPR2120-ASA-K9 delivers 6 Gbps firewall throughput for stateful packet inspection. When IPSec VPN encryption is enabled, throughput is 700 Mbps for small packets (450B UDP) or up to 1 Gbps for larger packets (1024B TCP with FastPath) due to cryptographic processing overhead.

Q: Can I add 10 Gigabit uplinks to the Firepower 2120?
A: The base FPR2120 platform includes 12x 1G RJ45 and 4x 1G SFP ports. Unlike the Firepower 2130/2140 models, the 2120 does not have a NetMod bay for expansion modules, so 10G uplinks are not available on this model.

Q: How is the Firepower 2120 ASA appliance managed?
A: Management options include the Cisco Adaptive Security Device Manager (ASDM) for local web-based management, command-line interface (CLI), or Cisco Defense Orchestrator (CDO) for cloud-based centralized policy management across distributed deployments.

Q: What deployment scenarios are ideal for the FPR2120-ASA-K9?
A: This appliance is designed for small to mid-size enterprise branch offices, Internet edge deployments, and data center perimeter security. It supports clustering, VPN concentrator roles with up to 3,500 peers, and delivers sustained performance for stateful firewall, NAT, and application control functions.
