The Cisco Nexus 7706 Switch Chassis (N77-C7706) is a high-performance, modular data center switching platform engineered for scalable, mission-critical network environments. Designed as part of the Cisco Nexus 7000/7700 Series, the Nexus 7706 delivers exceptional throughput, low latency, and high availability to support modern enterprise, cloud, and service provider data centers.
Featuring a 6-slot modular architecture with 2 supervisor slots and 4 I/O slots, the Nexus 7706 supports a wide range of 10G, 40G, and 100G Ethernet line cards, enabling flexible, high-density connectivity. With the appropriate fabric modules installed, the chassis delivers up to 550 Gbps per slot and a system switching capacity of up to 17.6 Tbps, making it ideal for core, aggregation, and spine-layer deployments.
Running Cisco NX-OS, the Nexus 7706 provides advanced Layer 2 and Layer 3 services, including VLANs, VRFs, VDCs, OSPF, BGP, EIGRP, IS-IS, multicast routing, and robust security features such as ACLs, uRPF, DHCP snooping, and Control Plane Policing (CoPP). Virtualization capabilities like Virtual Device Contexts (VDCs) allow multiple logical switches to operate independently on a single physical chassis.
Built for nonstop operations, the Cisco Nexus 7706 supports redundant supervisor modules, fabric modules, power supplies, and fan trays, along with In-Service Software Upgrade (ISSU) and nonstop forwarding to minimize downtime. Advanced resiliency technologies such as Virtual PortChannel (vPC) ensure loop-free, high-availability network designs.
With front-to-back airflow, support for AC or DC power, and NEBS Level 3 compliance (with DC power), the Nexus 7706 is well suited for data centers requiring reliability, regulatory compliance, and future-ready scalability. It also integrates seamlessly into Cisco ACI and spine-leaf architectures, enabling policy-driven automation and simplified operations.
