Cisco Integrated Services Routers from M&F Collaboration give branch, retail, and clinic sites a proven IOS XE WAN edge—modular ISR 4000 chassis, compact ISR 1000/1100 platforms, and fixed 900 Series LTE models. They're stocked for network and procurement teams refreshing circuits, adding cellular failover, or replacing aging branch routers.

  • ISR 4000 (ISR4221/K9-RF, ISR4351-V/K9-RF): modular GE ports, NIM/SM slots, and Cisco-documented performance licensing; UC options on voice-capable models.
  • ISR 1000 / 1100 (C1101, C1111, C1112, C1126X, ISR1100-6G): fixed GE LAN/WAN, optional LTE or DSL, PoE on select PIDs, SD-WAN-ready software.
  • 900 Series LTE (C921-4PLTEGB-RF): four GE LAN ports, dual GE WAN, and integrated CAT4 LTE for small sites. Not sure which chassis fits your WAN and license plan? Request a quote and we'll confirm ports, modules, and entitlements before you order.

How to choose a Cisco ISR router

A branch router only works if throughput, WAN media, and services line up. Cisco ISRs span modular ISR 4000 platforms, fixed ISR 1000/1100 boxes, and compact 900 Series LTE units. Work through these four checks before you order.

1. Match throughput and modularity

Cisco documents ISR 4000 aggregate throughput in default, performance-license, and boost tiers. The ISR4221/K9 starts at 35 Mbps default (75 Mbps performance, 1.2 Gbps CEF boost) with two GE ports and two NIM slots. The ISR4351-V/K9 starts at 200 Mbps default (400 Mbps performance, over 2 Gbps CEF boost) with three GE ports, three NIM slots, and two SM-X slots. Cisco states the ISR4221 does not support Unified Communications—use a -V UC bundle on a voice-capable 4300/4400-class chassis when the branch hosts survivable telephony.

2. Pick LAN, LTE, and DSL options in the PID

Compact ISR 1000 models bake interfaces into the part number. C1101-4P covers light sites with one GE WAN and four GE LAN ports. C1111-8P and C1111X-8P add eight GE LAN ports and dual GE WAN; the X marks 8 GB DRAM for app hosting. LTEEA models such as C1111-4PLTEEA and C1111-8PLTEEA add CAT6 LTE for EMEA/North America. C1112-8PLTEEA and C1113-8P bring G.FAST DSL WAN combinations, while C1126X-8PLTEP pairs VDSL/ADSL2+, pluggable LTE, PoE, and 8 GB memory. For SD-WAN-first Ethernet/fiber edges, see ISR1100-6G (four GE copper plus two 1G SFP). Small-site cellular CPE often fits C921-4PLTEGB.

3. Confirm licensing and mode

Cisco DNA Essentials and DNA Advantage subscriptions cover SD-WAN and routing feature tiers; autonomous IOS XE may also use perpetual IP Base, Security, App Experience, or UC licenses. Performance and boost licenses on ISR 4000 are separate from DNA tiers. Decide autonomous versus controller (Catalyst SD-WAN) mode before you buy, and confirm Smart Account entitlements for refurbished (-RF) hardware before cutover. HSEC may be required when encrypted tunnel scale exceeds export-control defaults.

4. Complete the BOM

Add NIM or pluggable modules from Cisco Expansion Modules, optics from Transceivers, cabling from Network Cables, and adapters from Cisco Power Supplies. Decode suffixes before you submit the RFQ: -RF means refurbished, /K9 marks strong cryptography, -V marks a Voice/UC bundle on supported ISR 4000 platforms, and LTEEA/LTEGB/LTEP describe cellular packaging. Browse sibling catalogs for Cisco 1100 Series Routers, 900 Series, and 800 Series.

Cisco ISR Router FAQs

Which Cisco ISR should I buy for a branch office?

Match throughput, WAN media, and services. Use ISR 4000 when you need NIM/SM modularity or UC. Use ISR 1000/C11xx when you want compact routing with built-in LAN and optional LTE or DSL. Use ISR1100-6G for SD-WAN Ethernet/fiber edges, and 900 Series LTE for very small dual-WAN cellular sites.

What does -RF mean on Cisco ISR part numbers?

On M&F Collaboration listings, -RF means refurbished—for example ISR4221/K9-RF or C1111X-8P-RF. Hardware follows the base Cisco PID; software entitlements still need Smart Account confirmation.

Does ISR4221 support voice or UC?

No. Cisco documents that ISR4221/K9 does not support Unified Communications. Choose a voice-capable platform such as ISR4351-V/K9 when the branch needs CME, SRST, or CUBE.

What is the difference between C1111-8P and C1111X-8P?

Both provide eight GE LAN ports and dual GE WAN. The X in C1111X-8P marks higher memory (8 GB DRAM/flash) for app hosting versus the base C1111-8P memory configuration.

How do Cisco DNA Essentials and Advantage differ on ISRs?

Essentials covers foundational SD-WAN management, limited segmentation, and core security services. Advantage adds unlimited segmentation, advanced analytics, and richer multicloud/SaaS capabilities. Neither replaces ISR 4000 performance or boost licenses.

Do I need separate modules for LTE on every ISR?

No. Many ISR 1000 and 900 Series PIDs include embedded or pluggable LTE in the part number (LTEEA, LTEP, LTEGB). Modular ISR 4000 platforms typically add cellular through NIM modules. Match the region suffix to your carrier bands.

Where can I find NIM modules and power supplies?

Browse Cisco Expansion Modules for NIMs and pluggables, and Cisco Power Supplies for adapters and spare PSUs. Include antennas and SFPs on the RFQ when the design uses LTE or fiber WAN.
