Overview of CISCO2911/K9
CISCO2911/K9 is a modular enterprise router engineered for robust performance and secure connectivity. It features a flexible architecture with dual WAN and four LAN interfaces, multiple power options including an AC power supply with redundant capability, and integrated services for voice, video, and WAN optimization. Offering modular expansion slots for NIM/EHWIC modules, this router is designed to support advanced VPN features with IPSec encryption, reliable firewall protection, and quality of service (QoS) mechanisms.
Built to meet demanding network environments, the CISCO2911/K9 delivers a throughput capacity of approximately 0.075 Gbps while ensuring redundancy and high availability. It accommodates a wide variety of use cases in enterprise settings with comprehensive routing protocols (OSPF, BGP, EIGRP, RIP, Static Routing), integrated security features, and full management via Telnet and SSH—all in a compact, rack-mount form factor.
CISCO2911/K9 price is $1,565.00, a 55.9% saving from the Cisco list price of $3,550.00. CISCO2911/K9 is in stock and available for next-day dispatch. (terms applied)

In a retail chain with 25 branch locations, the CISCO2911/K9-Cisco 2911 router w/3 GE, 4 EHWIC, 2 DSP, 1 SM, 256 MB CF & 512 MB DRAM is deployed at each store to terminate DMVPN and IPsec VPN tunnels back to headquarters. The integrated Security Services Module accelerates AES-256 encryption while the 3 Gigabit Ethernet ports aggregate diverse broadband circuits for high availability. This solution centralizes policy management, enforces PCI-DSS compliance and reduces MPLS costs by over 40 %. Outcome: robust, end-to-end data protection and predictable WAN performance across all sites.
A healthcare clinic network leverages the CISCO2911/K9-Cisco 2911 router w/3 GE, 4 EHWIC, 2 DSP, 1 SM, 256 MB CF & 512 MB DRAM to consolidate voice, video and fax over a single WAN link. Two DSP modules support up to 60 simultaneous voice channels; EHWIC slots host analog and digital interface cards while QoS profiles guarantee real-time traffic priority. The built-in Unified Communications features reduce equipment footprint and simplify provisioning through Cisco Unified Communications Manager. Outcome: enhanced call quality, streamlined administration and scalable voice infrastructure without forklift upgrades.
A financial services firm deploys the CISCO2911/K9-Cisco 2911 router w/3 GE, 4 EHWIC, 2 DSP, 1 SM, 256 MB CF & 512 MB DRAM as an SD-WAN edge device to connect trading platforms hosted in AWS and on-premises data centers. Application Visibility and Control (AVC) plus Performance-Based Routing steer critical FIX and VoIP traffic over low-latency MPLS, while less-sensitive SaaS traffic uses broadband. The Security Services Module enforces firewall and intrusion prevention while consistent CF/DRAM resources sustain high throughput under peak loads. Outcome: deterministic performance for mission-critical apps, simplified cloud on-ramps and up to 30 % reduction in bandwidth spend.
