The Cisco ASR 901 (A901-6CZ-FS-A) is a compact, carrier-grade aggregation router engineered for mobile backhaul, metro Ethernet, and enterprise edge deployments. Built on Cisco IOS XE, the ASR 901 delivers powerful Layer 2 and Layer 3 services, integrated security, and high availability in a rugged, space-efficient design—ideal for service providers and enterprises operating in demanding environments.
Equipped with six combo Ethernet ports, the ASR 901 supports both 1G and 10G connectivity using SFP, SFP+, or RJ-45 interfaces, allowing flexible deployment across fiber and copper infrastructures. With a switching capacity of up to 60 Gbps and line-rate forwarding on all ports, it ensures consistent, high-performance transport for voice, video, and data traffic.
Designed specifically for IP-RAN and mobile backhaul networks, the Cisco ASR 901 supports a comprehensive suite of Carrier Ethernet services, including EVC, L2VPN, VPLS, pseudowires, and advanced MPLS capabilities. It also supports modern routing protocols such as BGP, OSPF, IS-IS, EIGRP, along with Segment Routing, RSVP-TE, and LDP, enabling scalable and resilient network architectures.
Security is deeply integrated into the platform, featuring IPSec for secure WAN backhaul, NAPT, ACL-based traffic filtering, control-plane protection, and IEEE 802.1X authentication. MACsec readiness (license-dependent) further enhances data confidentiality for critical infrastructure deployments.
The fanless, hardened chassis supports extreme operating temperatures ranging from -40°C to +65°C, making the ASR 901 suitable for outdoor cabinets, cell sites, and industrial locations. Its low power consumption (~90W) and built-in AC power supply ensure energy-efficient operation without compromising performance.
For operations and automation, the Cisco ASR 901 supports CLI, WebUI, SNMP, NetFlow, telemetry, REST APIs, and YANG models, along with Zero Touch Provisioning (ZTP). Seamless integration with Cisco Prime, EPN Manager, NSO, and SD-WAN frameworks simplifies lifecycle management and accelerates deployment.
In summary, the Cisco ASR 901 A901-6CZ-FS-A is a reliable, secure, and scalable aggregation router that delivers carrier-class performance in a compact form factor—perfect for metro access, mobile backhaul, and enterprise edge networks.
