FPR2120-NGFW-K9 Description

The FPR2120-NGFW-K9 is a Cisco Firepower 2100 Series NGFW appliance running Threat Defense software for branch and network-edge firewalls. The 1RU appliance delivers 3.4 Gbps of FW + AVC + IPS throughput and 1.5 million concurrent sessions with AVC, with twelve Gigabit RJ-45 ports, four 1G SFP ports and 3,500 VPN peers. The chassis has no network module bay, and its single 250W AC supply is integrated with no redundant option.

Key Features

Fixed 16-Port Layout

Twelve 10M/100M/1GBASE-T RJ-45 ports and four 1G SFP ports are built in. With no network module bay, the interface count stays at 16.

Inspection And VPN Capacity

Threat Defense runs at 3.4 Gbps with FW + AVC + IPS enabled, handles 18,000 new connections per second with AVC, and sustains 1.2 Gbps of IPsec VPN across 3,500 peers.

Integrated Power And Fans

The 250W AC supply is built into the chassis and the fans are fixed. Neither can be swapped in the field, and no second supply can be added.

Application Scenarios

Branch Internet Edge

At a branch office, the appliance sits between the WAN router and the LAN switches, with Gigabit RJ-45 ports facing the switches and 1G SFP ports for fiber handoff from the provider.

Remote-Access VPN Termination

A regional office can terminate site-to-site and remote-user tunnels on the appliance, which supports 3,500 VPN peers at 1.2 Gbps of IPsec throughput.

Threat Inspection At A Small Perimeter

For a perimeter with a few Gbps of traffic, the appliance runs application visibility and intrusion prevention together at 3.4 Gbps without a separate IPS box.

FPR2120-NGFW-K9 and FPR2120-ASA-K9 are the same Firepower 2120 chassis, but the NGFW PID runs Threat Defense at 3.4 Gbps of FW + AVC + IPS, while FPR2120-ASA-K9 runs Cisco ASA at 6 Gbps of stateful inspection, so a site with ASA policies needs the ASA PID. Traffic below 2.6 Gbps of inspected throughput fits FPR2110-NGFW-K9, which keeps the same 12 RJ-45 and four 1G SFP ports but supports 1,500 VPN peers instead of 3,500. Uplinks that need 10G SFP+, a network module bay, a second power supply (the 2120 has one fixed 250W supply) or 5.4 Gbps of inspected throughput call for FPR2130-NGFW-K9.

Ordering Checklist

  • Threat Defense subscription: Add L-FPR2120T-TMC= and pick a 1, 3 or 5 year term (L-FPR2120T-TMC-1Y, -3Y or -5Y). Only the Base license comes with the appliance; IPS, Malware Defense and URL Filtering stay unlicensed without a subscription.
  • SFP optics: Order 1G SFP transceivers for the four fixed SFP ports (Ethernet 1/13 to 1/16). SFP transceivers ship in the box only when ordered with the system.
  • Rack mounting: Two 2-post brackets are included; add FPR2K-SLIDE-RAILS for a 4-post rack. The included brackets do not fit a 4-post rack.
  • Malware Storage Pack: Add FPR-MSP-SSD for the second SSD slot, which is reserved for it. Slot 2 stays empty unless the pack is added.
  • Power cord: Select a country-specific cord such as CAB-AC, CAB-ACE or CAB-ACA, and order CAB-ACR, CAB-C13-ACB or CAB-JPN with the system for Argentina, Brazil or Japan. Orders to those three countries must include the matching cord, and the single power supply cannot be added to or replaced in the field.

Questions & Answers

  • How much memory does FPR2120-NGFW-K9 have?

    FPR2120-NGFW-K9 has 16 GB of system memory and 8 GB of Cavium NPU RAM, per the Firepower 2100 hardware installation guide. Flash is 8 GB nominal. Storage is separate: one 100 GB SSD ships in slot 1, and slot 2 stays empty for the Malware Storage Pack.
  • Which spare PID replaces a failed FPR2120-NGFW-K9 chassis?

    A failed FPR2120-NGFW-K9 is replaced as a whole unit with the FPR2120-K9= spare, which ships without a power supply or fans, per the Firepower 2100 hardware installation guide. The supply and fans are fixed parts and cannot be swapped in the field, so the chassis itself is the replacement unit.
  • What AC input does FPR2120-NGFW-K9 need?

    FPR2120-NGFW-K9 takes 100/240V AC at 50 to 60 Hz with a maximum input current below 2.7A at 100V and system power of 1.9 A at 100 VAC. The single integrated 250W supply has no redundant PSU option.
  • What TLS inspection rate does FPR2120-NGFW-K9 reach?

    FPR2120-NGFW-K9 inspects TLS traffic at 475 Mbps. Traffic that goes through TLS inspection is bounded by that figure, which sits well below the 3.4 Gbps FW + AVC + IPS rating. Local configuration uses Cisco Firepower Device Manager, and High availability is Active/standby.
