FPR3120-NGFW-K9 Description

The FPR3120-NGFW-K9 is a Cisco Secure Firewall 3120 next-generation firewall appliance with Threat Defense software for internet-edge and data center security. The 1RU appliance is rated at 21.0 Gbps of firewall, application visibility and IPS throughput on 1024B packets, with 4 million concurrent sessions with AVC, 10 Gbps of IPsec VPN throughput and 7,000 VPN peers across 8 RJ-45 and 8 1/10G SFP+ ports. The single network module slot recognizes only 1G and 10G modules, so 25G, 40G and 100G modules are not usable even though they fit physically.

Key Features

Threat Defense Software With Model-Specific Licenses

The appliance runs Threat Defense, and IPS, malware defense and URL filtering are licensed through L-FPR3120T subscriptions, each offered as a 1-, 3- or 5-year term.

IPS At The Full 21 Gbps Rating

Adding IPS does not lower the published figure: firewall with application visibility and the full FW + AVC + IPS profile are both rated at 21.0 Gbps on 1024B packets. Real results still move with the enabled features, the protocol mix and the packet sizes on the link.

TLS Decryption Capacity

Decryption is the tighter limit on this model. TLS throughput is 6.7 Gbps, measured with half the traffic as TLS 1.2 using AES256-SHA and 2048-bit RSA keys, and a policy that decrypts a large share of sessions should be sized from that number.

IPsec VPN Throughput And Peers

IPsec VPN is rated at 10 Gbps for 1024B TCP traffic over Fastpath, with up to 7,000 VPN peers per appliance. With VPN offload on Threat Defense 7.2, the projected figure rises to 13.5 Gbps.

One Network Module Slot At 1G And 10G

A single network module slot takes the 16 fixed ports to as many as 24. The slot accepts the 8-port FPR3K-XNM-8X10G and the 1G and 10G hardware-bypass modules, while FPR3K-XNM-8X25G, FPR3K-XNM-4X40G and the 2-port 100G module are not recognized by the software.

Single 400W Supply With A Second Bay

One of the two power supply bays is filled with a 400W AC supply. Redundancy starts when a second supply is added for 1+1 operation, and 400W DC supplies can replace the AC units, though AC and DC supplies cannot share a chassis.

Application Scenarios

Internet Edge Inspection

At the internet edge of a headquarters or campus network, the firewall sits between the core and the service provider links and applies access control, IPS and URL filtering to traffic in both directions.

Branch VPN Hub

Branch offices build their site-to-site IPsec tunnels to the appliance at a central site, which puts branch traffic and internet traffic under one Threat Defense policy.

Inline IPS Between Data Center Segments

Inside a data center or private cloud, the appliance can run as a dedicated inline IPS between server segments, and a hardware-bypass network module keeps paired ports forwarding traffic if the appliance itself fails.

L-FPR3130T Threat Defense licenses and subscriptions

FPR3120-NGFW-K9 runs Threat Defense with Firewall Device Manager and L-FPR3120T subscriptions, while FPR3120-ASA-K9 is the same 3120 hardware on ASA with ASDM and the L-FPR3K-ENC-K9= and L-FPR3K-ASASC licenses; its 22.0 Gbps figure is 1500B UDP stateful inspection and does not compare directly with 21.0 Gbps of FW + AVC + IPS at 1024B. Sites that standardize on ASA order FPR3120-ASA-K9. Inspected load under 17.0 Gbps and 2 million sessions fits FPR3110-NGFW-K9, which also lowers VPN peers from 7,000 to 3,000. Links at 25G, or loads up to 38.0 Gbps with 6 million sessions, need FPR3130-NGFW-K9, whose fixed SFP ports run 1/10/25G while the other three stop at 1/10G.

Ordering Checklist

  • Threat Defense subscription: Order a term PID such as L-FPR3120T-TMC-5Y; T, TM, TC, TMC, URL and AMP each come in -1Y, -3Y and -5Y terms. Threat (T) is the prerequisite for Malware (M) and URL (C), so a URL-only or AMP-only line leaves those features unusable.
  • Smart Licensing account: Set up the end customer’s Smart Licensing account in Smart Software Manager before the Threat Defense order. All ordered licenses are deposited into that account, so a missing account leaves them with nowhere to land.
  • Threat Defense release: Run Threat Defense 7.1 or later, not 7.4.0; multi-instance mode needs 7.4.1 or later. 7.4.0 is not supported on this chassis, and container instances are unavailable on earlier releases.
  • Network module: Choose FPR3K-XNM-8X10G, FPR3K-XNM-6X1SXF, FPR3K-XNM-6X10SRF, FPR3K-XNM-6X10LRF or FPR3K-XNM-8X1GF, not FPR3K-XNM-8X25G or FPR3K-XNM-4X40G. The 25G, 40G and 100G modules are not recognized by the software on this chassis, and a different module type needs a reboot.
  • Second power supply: Add a second FPR3K-PWR-AC-400= for 1+1 redundancy, and never mix AC with DC supplies in one chassis. The default is one 400W AC supply.
  • Second SSD: Add FPR3K-SSD900= for SSD slot 2, which is reserved for software RAID1. The chassis ships with one 900 GB SSD, and an SSD from another firewall series cannot be used.
  • Rack kit: Put FPR3K-SLIDE-RAILS= or FPR3K-BRKT= on the order; slide rails are recommended. Slide rails and rack-mount brackets are in the package only if ordered.

    Needed higher throughput for our datacenter edge. The 3120 handles full packet inspection comfortably.

Questions & Answers

  • What throughput does FPR3120-NGFW-K9 reach with firewall, AVC and IPS enabled?

    FPR3120-NGFW-K9 is rated at 21.0 Gbps with firewall, application visibility and IPS enabled on 1024B packets. TLS decryption is rated at 6.7 Gbps, measured with half the traffic as TLS 1.2 using AES256-SHA and 2048-bit RSA keys.
  • Do IPS, malware defense and URL filtering on FPR3120-NGFW-K9 need a subscription?

    Yes. FPR3120-NGFW-K9 runs Threat Defense, and IPS, malware defense and URL filtering are licensed through L-FPR3120T subscriptions such as L-FPR3120T-TMC-5Y, each in 1, 3 or 5 year terms. Threat (T) is the prerequisite for Malware (M) and URL (C).
  • What does FPR3100-FTD-HA-BUN order for a FPR3120-NGFW-K9 high-availability pair?

    FPR3100-FTD-HA-BUN orders two identical 3100 chassis together with their software subscriptions, to be configured as a high-availability pair. It applies when both FPR3120-NGFW-K9 units are bought together as a new pair.
  • Which Threat Defense releases support FPR3120-NGFW-K9, and which one does not?

    FPR3120-NGFW-K9 is supported on Threat Defense 7.1, 7.2, 7.3, 7.4.1 through 7.4.x, 7.6, 7.7 and 10.x. Release 7.4.0 is not supported. The same release list applies to management through Firewall Management Center and Firewall Device Manager, per the Threat Defense compatibility guide.
  • Which legacy network module PIDs does FPR3120-NGFW-K9 not recognize?

    FPR3120-NGFW-K9 does not recognize FPR-X-NM-4X40G (40G) or FPR-X-NM-8X25G (1/10/25G). Per the Secure Firewall 3100 maintenance guide, these modules work only in the 3130 and 3140, so leave them out of any module plan and use the 1G and 10G modules instead.
  • How many SSD, power supply and fan module bays does FPR3120-NGFW-K9 have, and how many are populated?

    FPR3120-NGFW-K9 has 2 SSD bays with 1 SSD fitted, 2 power supply bays with 1 supply fitted, and 2 fan module bays with both fan modules fitted. Only the second SSD and the second power supply are open for expansion, per the Cisco Secure Firewall ordering guide.
