Le Cisco ASR 1001-X Aggregation Services Router is a highly reliable and compact routing platform designed to deliver secure, scalable, and high-performance network services. Part of the ASR 1000 Series, the ASR 1001-X offers advanced routing and security functions in a 1RU form factor, making it ideal for enterprises, service providers, and government organisations that require robust WAN aggregation, enterprise edge routing, and cloud connectivity.
This router was engineered to address the evolving needs of modern networks, where efficiency, service integration, and scalability are essential. It provides a system bandwidth of up to 20 Gbps, making it suitable for mid-sized environments and high-performance branch deployments. Its software-driven flexibility and support for rich network services enable organisations to future-proof their infrastructure without frequent hardware replacements.
Carritech continues to support the Cisco ASR 1001-X by sourcing original hardware, spare parts, and modules that are increasingly difficult to obtain. In addition, Carritech provides expert repair services and Level 3 (L3) remote technical support, ensuring operators can maintain their ASR 1001-X systems well beyond standard vendor lifecycles. This allows organisations to maximise return on investment while maintaining a stable and secure network infrastructure.
The Cisco ASR 1001-X is powered by Cisco’s QuantumFlow Processor (QFP) architecture, which enables line-rate performance for advanced services while maintaining predictable throughput. With an initial throughput of 2.5 Gbps, organisations can increase bandwidth up to 20 Gbps via performance licensing, allowing gradual scaling based on demand without replacing hardware.
The device integrates six built-in Gigabit Ethernet (RJ-45/SFP) ports and two 10 Gigabit Ethernet ports, offering flexible connectivity out of the box. Additionally, it supports one modular port adapter (MPA) slot, enabling further expansion and interface diversity. Its built-in redundancy, including dual power supply options and hot-swappable components, ensures high availability for mission-critical environments.
Software-wise, the ASR 1001-X operates on Cisco IOS XE, which decouples the control plane and data plane for improved resiliency. The operating system supports programmability through APIs and facilitates integration with automation frameworks and SDN controllers. Features such as in-service software upgrades (ISSU) help reduce downtime during maintenance activities.
Security is a strong focus of the ASR 1001-X, with embedded hardware acceleration for IPsec encryption and full support for VPN services. The router also integrates QoS, deep packet inspection, and application-aware routing to optimise performance for voice, video, and business-critical applications. Its design is tailored for enterprises that require a balance of compactness, flexibility, and reliable service delivery.
