FPR3120-ASA-K9 Description

The FPR3120-ASA-K9 is a Cisco Secure Firewall 3120 ASA appliance for edge firewall and VPN deployments that run Cisco Secure ASA software. The 1RU firewall provides 22.0 Gbps of stateful inspection throughput on 1500B UDP, 4 million concurrent connections, 10 Gbps of IPsec VPN throughput on a 450B UDP L2L test and 7,000 VPN peers across 8 RJ-45 and 8 1/10G SFP ports. Its single network module slot takes 1G and 10G modules only, and ASA clustering supports up to 8 chassis.

Key Features

Stateful And Multiprotocol Throughput

Stateful inspection is rated at 22.0 Gbps on 1500B UDP, while the 17.0 Gbps multiprotocol figure reflects a TCP-heavy mix of HTTP, SMTP, FTP, IMAPv4, BitTorrent and DNS.

Connection Scale

A single appliance holds 4 million concurrent connections and sets up 500,000 new connections per second, double the 2 million connections of FPR3110-ASA-K9.

VPN Throughput And Peer Count

IPsec VPN reaches 10 Gbps on the 450B UDP L2L test and 7,000 peers. With VPN offload on ASA 9.18, the projected figure is 15.4 Gbps.

Clustering, Contexts And Failover

ASA clusters join up to 8 chassis, and active/active and active/standby pairs are available. Two security contexts come with the platform and the maximum is 100.

Fixed Ports And 1G/10G Module Slot

Eight RJ-45 ports and eight 1/10G SFP ports are fixed, with up to 24 Ethernet ports once the module slot is filled. Modules for 25G, 40G and 100G fit physically but are not recognized, so expansion stays at 1G and 10G.

Power, Cooling And Storage

A 400W AC supply is fitted with a second bay for 1+1 redundancy, and two dual-fan modules provide 3+1 cooling redundancy. One 900 GB SSD ships in slot 1, with slot 2 held for RAID1.

Application Scenarios

Campus Internet Edge

At the internet edge of a campus or headquarters, the appliance applies ASA inspection to traffic between the core and the provider links, which attach to its 1/10G SFP ports.

Central VPN Concentrator

A central site terminates site-to-site and remote-user IPsec tunnels on the appliance, which supports up to 7,000 VPN peers and 10 Gbps of IPsec VPN throughput.

Clustered Data Center Edge

A data center edge that outgrows one firewall adds chassis to an ASA cluster of up to 8 units, with 4 million concurrent connections handled per appliance.

FPR3120-ASA-K9 is the 22 Gbps ASA model of this group: against FPR3110-ASA-K9 at 18 Gbps it doubles connections to 4 million and raises VPN peers from 3000 to 7000, on the same 1/10G fixed ports and 1RU chassis. FPR3120-NGFW-K9 is the same Secure Firewall 3120 hardware with Threat Defense software, for sites that run Threat Defense instead of ASA. FPR3130-ASA-K9 is the choice for 25G: its eight fixed SFP ports run at 1/10/25G, separate from its optional network modules, which include 25G, 40G and 100G options that this model does not recognize. It reaches 42 Gbps, 6 million connections and 15000 peers with two 400W AC supplies fitted.

Ordering Checklist

  • Network module: Choose FPR3K-XNM-8X10G, or a hardware bypass module such as FPR3K-XNM-8X1GF, FPR3K-XNM-6X1SXF, FPR3K-XNM-6X10SRF or FPR3K-XNM-6X10LRF. FPR3K-XNM-8X25G, FPR3K-XNM-4X40G and the 100G module are not recognized by software in this model.
  • Redundant power: Add FPR3K-PWR-AC-400= for a redundant AC unit, or FPR3K-PWR-DC-400= for DC. Power redundancy exists only when a redundant unit is ordered; AC and DC units cannot be mixed in one chassis.
  • Second SSD: Add FPR3K-SSD900= for slot 2. One 900 GB SSD ships in slot 1, and slot 2 is the RAID1 mirror.
  • Rack mounting: Order the FPR3K-SLIDE-RAILS= slide rail kit, which is recommended, or FPR3K-BRKT= rack-mount brackets. Rails and brackets are packed only when ordered.
  • ASA licenses: Add L-FPR3K-ASASC-5= or L-FPR3K-ASASC-10= for more than the 2 included contexts, and L-FPR3K-ENC-K9= for strong encryption. These are separate order lines, and the encryption license is not available in export-restricted regions.

Questions & Answers

  • What throughput does FPR3120-ASA-K9 reach as an ASA firewall?

    FPR3120-ASA-K9 is rated at 22.0 Gbps of ASA stateful inspection throughput on 1500B UDP. The 17.0 Gbps multiprotocol figure reflects a TCP-heavy mix of HTTP, SMTP, FTP, IMAPv4, BitTorrent and DNS, and the appliance sets up 500,000 new connections per second.
  • Does FPR3120-ASA-K9 run Threat Defense or ASA, and which licenses does it use?

    FPR3120-ASA-K9 runs Cisco Secure ASA software, first supported in ASA 9.17(1). Two security contexts are included, and L-FPR3K-ASASC-5= or L-FPR3K-ASASC-10= add contexts up to 100. L-FPR3K-ENC-K9= adds strong encryption and is not available in export-restricted regions.
  • How much system memory does FPR3120-ASA-K9 have?

    FPR3120-ASA-K9 has 128 GB of system memory, per the Secure Firewall 3100 hardware installation guide. The memory is fixed in the chassis and has no field-orderable upgrade option, so size policy and logging load against that amount.
  • How many SSD, power supply and fan module bays does FPR3120-ASA-K9 have, and how many are populated?

    FPR3120-ASA-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.
  • Which legacy network module PIDs does FPR3120-ASA-K9 not recognize?

    FPR3120-ASA-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 do not plan them for this slot and use the 1G and 10G modules instead.
  • What does a fully equipped FPR3120-ASA-K9 weigh for rack planning?

    A typical FPR3120-ASA-K9 weighs 23 lb (10.5 kg), counted with one power supply, one network module, two dual fan modules and one SSD, per the 3100 hardware installation guide. A second power supply and a second SSD add to this figure, so check the rack shelf or rail rating before mounting.
