ISR4461/K9 Description

The ISR4461/K9 is a Cisco ISR 4461 router from the Cisco 4000 Family Integrated Services Routers for large branch and regional WAN edges that terminate 10G circuits. Two onboard 10G SFP+ ports sit beside four 1G ports that each run as RJ-45 or SFP, and the chassis adds three NIM slots, three SM-X slots and 1.5 Gbps of aggregate throughput that a performance license raises to 3 Gbps. Encrypted traffic is held to 1,000 secure tunnels and 250 Mbps until an HSEC license is installed.

Key Features

10G Ports On The Chassis

Ports TE 0/0/4 and TE 0/0/5 take 10G SFP+ optics, so a 10G handoff lands on the router without a module. The four 1G ports stay dual-media: each one runs as RJ-45 or SFP, and the media-type command picks which.

Three SM-X Slots For Service Modules

Each SM-X slot connects to the system at up to 10 Gbps, and two of the three can hold double-wide modules. The slots accept Cisco UCS E-Series server modules for local compute, and a carrier card turns an SM-X slot into an extra NIM slot.

Throughput Raised By License

The router forwards 1.5 Gbps of aggregate traffic as shipped. FL-4460-PERF-K9, delivered remotely, raises that to 3 Gbps with no hardware change, while FL-4460-BOOST-K9 covers CEF-only forwarding.

Encryption Limits And HSEC

Without HSEC, IPsec stops at 1,000 secure tunnels and 250 Mbps of crypto bandwidth. The HSEC license lifts both limits, requires the securityk9 package and has no evaluation period. WAN MACsec on NIM-2GE-CU-SFP needs the Security and HSEC licenses together.

Redundant Power And Endpoint PoE

Two internal bays take AC, DC or PoE supplies, with PWR-4460-650-AC2 as the redundant 650W AC unit. A PoE supply delivers 500W to endpoints when PoE is redundant, or 950W in PoE boost mode without redundancy.

NEBS Build For Carrier Sites

The ISR 4461 is NEBS certified. The NEBS kit fits dual 650W DC reverse-airflow supplies and a reverse-airflow fan assembly, and ACS-4460-NEBSKIT2 keeps the third SM slot usable from Cisco IOS XE 17.9.

Application Scenarios

Regional Office On 10G Circuits

A regional office lands its 10G internet or MPLS circuit on an onboard SFP+ port, keeps a 1G copper or fiber backup on the dual-media ports and routes traffic for the floors behind it.

Catalyst SD-WAN Aggregation Site

At a site that gathers SD-WAN tunnels from smaller branches, the router joins the overlay in controller mode, running the same universalk9 image it uses for autonomous routing.

Carrier Central Office

Telecom central offices that run on DC power can install the router in its NEBS-certified build, with reverse-airflow DC supplies and a matching fan assembly.

ISR4461/K9 and ISR4451-X/K9 share four dual-media 1G ports, three NIM slots and the same 950W endpoint PoE ceiling, but ISR4461/K9 adds two 10G SFP+ ports and a third SM-X slot. ISR4461/K9 also forwards 1.5 Gbps by default and 3 Gbps licensed, against 1 Gbps and 2 Gbps. A branch on 1G circuits that stays under 2 Gbps and runs no more than two service modules fits ISR4451-X/K9. Where SD-WAN encryption is the main load, C8300-2N2S-4T2X keeps the two 10G ports and publishes up to 18.8 Gbps of SD-WAN IPsec at 1400 bytes, with two SM, two NIM and one PIM slot. C8300-1N1S-4T2X carries the same port mix and up to 17 Gbps in 1RU, at one SM and one NIM slot.

Ordering Checklist

  • Software mode: With a Cisco DNA subscription, choose autonomous mode, which is perpetual, or controller mode for Catalyst SD-WAN, which is term-based. ISR4461-DNA is the router ordered with DNA support.
  • Technology package: The base ISR4461/K9 activates only ipbasek9; security, voice and application features need licenses or a bundle such as ISR4461-SEC/K9, ISR4461-V/K9 or ISR4461-AX/K9.
  • HSEC license: Add an HSEC license when encryption must exceed 250 Mbps or 1,000 secure tunnels. It requires the securityk9 package and has no evaluation license.
  • Performance license: Order FL-4460-PERF-K9 when the site needs 3 Gbps of aggregate throughput. Without it the router stays at 1.5 Gbps.
  • Memory and flash: Control-plane DRAM takes single DIMMs such as MEM-4460-16G or MEM-4460-32G up to 32 GB. MEM-FLSH-8GU16G or MEM-FLSH-8GU32G takes flash from 8 GB to 16 GB or 32 GB.
  • Second power supply: Add PWR-4460-650-AC2 for redundant AC or PWR-4460-650-DC2 for redundant DC. An empty bay takes PWR-COVER-4450 and an empty PoE slot takes POE-COVER-4450.

Questions & Answers

  • What aggregate throughput does ISR4461/K9 provide?

    ISR4461/K9 delivers 1.5 Gbps of aggregate throughput by default. FL-4460-PERF-K9 raises it to 3 Gbps and is delivered remotely with no hardware change. Until an HSEC license is installed, encryption is held to 1,000 secure tunnels and 250 Mbps of crypto bandwidth.
  • Which licenses does ISR4461/K9 need beyond IP Base?

    ISR4461/K9 activates only ipbasek9 by default, so security, voice and application features need securityk9, uck9 and appxk9 licenses. An HSEC license, which requires securityk9 and has no evaluation period, is needed beyond 1,000 secure tunnels or 250 Mbps of encryption.
  • Which ROMMON release does ISR4461/K9 need for IOS XE 16.9 and for IOS XE 17.6?

    ISR4461/K9 needs ROMMON 16.9(1r) for IOS XE 16.9.x through 16.12.x, and ROMMON 16.12(2r) for IOS XE 17.1.x through 17.6.x, per the Cisco ISR 4000 software installation guide. The guide has no entry through IOS XE 16.8.x, so 16.9.x is the earliest train for this router.
  • From which IOS XE release does ISR4461/K9 support a third SM slot with the NEBS kit?

    ISR4461/K9 supports the third SM slot with the ACS-4460-NEBSKIT2 NEBS kit 2.0 from IOS XE 17.9. The earlier ACS-4460-NEBS-KIT is also listed, with ACS-4460-NEBS-FAN, ACS-4460-NEBS-FLT and ACS-4460-NEBS-FTA as NEBS fan and filter parts.
  • Which cover PIDs fill empty slots on ISR4461/K9?

    PWR-COVER-4450= covers an empty second power supply slot and POE-COVER-4450= covers an empty PoE slot on ISR4461/K9. SM-S-BLANK is the faceplate for an unused service-module slot. Fit these covers so open bays are closed on a chassis that stays in service.
  • Can ISR4461/K9 use NIM-PVDM-X voice DSP modules?

    Yes. NIM-PVDM-X DSP modules occupy a NIM slot on ISR4461/K9 and carry up to 256 channels for IP voice. Each module uses one of the three NIM slots, so count the slots before adding other NIMs.
  • Which bundle PIDs exist for ISR4461/K9?

    ISR4461-SEC/K9 adds the Security license and ISR4461-AX/K9 adds the APP and SEC licenses. ISR4461-V/K9 and ISR4461-AXV/K9 add UC and CUBE-25 voice licensing, and ISR4461-VSEC/K9 combines voice with Security. Order ISR4461/K9 alone when the router should carry the IP Base license only.
