FPR4245-NGFW-K9 Description

The FPR4245-NGFW-K9 is a Cisco Secure Firewall 4200 Series 1RU next-generation firewall that runs Threat Defense for high-throughput data center and internet edge inspection. The appliance provides 140 Gbps of FW + AVC + IPS throughput, 60 million concurrent sessions with AVC, 140 Gbps of IPsec VPN throughput and 1 TB of memory, with eight fixed 1/10/25G SFP28 ports and two network module slots. The chassis takes 200 to 240 VAC high-line input only, and device manager is not supported, so management runs through Firewall Management Center or Cisco Defense Orchestrator.

Key Features

140 Gbps Threat Defense Inspection

FW + AVC + IPS runs at 140 Gbps, the highest figure among the 4215, 4225 and 4245 chassis. AVC session scale reaches 60 million, with 800K new connections per second.

140 Gbps IPsec VPN

IPsec VPN throughput matches the inspection figure, with 30000 peers supported. Large tunnel counts do not require a separate VPN appliance.

45 Gbps TLS Hardware Decryption

Hardware decryption covers 45 Gbps of TLS traffic. Inspecting encrypted flows therefore stays off the general inspection budget.

Multi-Instance And Clustering

One chassis can run as many as 34 logical firewalls, and up to 16 chassis can join a cluster. Active/standby pairs are also supported.

Fixed SFP28 Ports Plus Module Slots

Eight 1/10/25G SFP28 ports are built in, and two hot-swappable slots take modules from 1G through 400G, including hardware-bypass types. Interface layout is set by the chosen modules.

High-Line AC Power

Dual 1900W supplies run 1+1 on 200 to 240 VAC and draw up to 1380 W. Racks with 100 to 120 VAC feeds cannot power this chassis.

Application Scenarios

Threat Defense Internet Edge

At the edge of a large enterprise, the firewall applies AVC and IPS to 140 Gbps of traffic and holds 60 million concurrent sessions with AVC.

Clustered Data Center Perimeter

A data center perimeter can grow by joining up to 16 chassis in a cluster, while the eight fixed SFP28 ports and two network module slots provide the 25G to 100G links toward the core.

High-Capacity VPN Termination

Remote-access and site-to-site tunnels from up to 30000 peers terminate on the firewall, with 140 Gbps of IPsec VPN throughput behind them.

FPR4245-NGFW-K9 is the top Threat Defense model in this group: against FPR4225-NGFW-K9 it raises memory from 512 GB to 1 TB, FW + AVC + IPS throughput from 80 Gbps to 140 Gbps, AVC sessions from 30 million to 60 million, new connections with AVC from 600K to 800K, and IPsec VPN from 80 Gbps to 140 Gbps. It also needs 200 to 240 VAC high-line input at 1380 W, so a rack on 100 to 120 VAC circuits points to FPR4225-NGFW-K9. Sites that run Cisco Secure ASA with Cisco Security Manager or ASDM order FPR4245-ASA-K9, which keeps the 1 TB memory and 30000 VPN peers but lists 180 Gbps of stateful firewall throughput and 70 Gbps of IPsec VPN under the ASA table.

Questions & Answers

  • What console settings does FPR4245-NGFW-K9 use?

    FPR4245-NGFW-K9 has one RJ-45 serial console port set to RS-232 at 9600 bps, 8N1, with no flow control. The serial cable is not included by default, so add one to the order if the chassis will be set up locally, per the Secure Firewall 4200 hardware installation guide.
  • What USB media does FPR4245-NGFW-K9 accept?

    FPR4245-NGFW-K9 has one USB 3.0 Type A port that supplies 5 V at up to 1 A. It reads EXT2, EXT3, EXT4 or VFAT/FAT32 media and appears as disk1: in Threat Defense, usbA: in FXOS and usb: in ROMMON. The port cannot upload CSP images.
  • Which cable types connect to the management ports on FPR4245-NGFW-K9?

    The two 1/10/25-Gbps SFP28 management ports on FPR4245-NGFW-K9 take fiber modules, DAC cables or GLC-TE copper modules, per the Secure Firewall 4200 hardware installation guide. Copper management therefore needs a GLC-TE module because there is no built-in RJ-45 management port.
  • Where is the power switch on FPR4245-NGFW-K9 and what does OFF do?

    The power switch on FPR4245-NGFW-K9 is at the rear, to the left of PSU-1. Setting it to OFF starts a graceful shutdown rather than cutting power immediately, per the Secure Firewall 4200 hardware installation guide.
  • Does swapping a network module in FPR4245-NGFW-K9 need a reboot?

    It depends on the module. FPR4245-NGFW-K9 has two hot-swappable slots, NM-2 and NM-3, and a module can be replaced live with an identical one. Installing a different module type requires a reboot, per the Secure Firewall 4200 hardware installation guide.
  • How much does FPR4245-NGFW-K9 weigh empty and fully populated?

    FPR4245-NGFW-K9 weighs 36 lb (16.3 kg) empty and 46 lb (20.8 kg) fully populated, per the hardware installation guide. Empty means no power supplies, network modules or fans. Plan the rack install and lift for the populated weight.
