The Cisco Nexus® 7700 F2-Series Enhanced 48-Port Fiber 1 and 10 Gigabit Ethernet Module (referred to as the Cisco Nexus 7700 F2e-Series module in this document) offers outstanding feature flexibility and wire-rate performance on each port. The module enables the deployment of high-density, low-latency, scalable data center architecture.
Powering Cisco's Unified Fabric Architecture
The Cisco Nexus 7000 Series Switches are the foundation of the Cisco® Unified Fabric solution. Designed to meet the requirements of mission-critical data centers, these switches deliver exceptional availability, outstanding scalability, and the proven and comprehensive Cisco NX-OS Software data center switching feature set.
The Cisco Nexus 7700 platform is the latest extension to the Cisco Nexus 7000 Series modular switches. With more than 83 terabits per second (Tbps) of overall switching capacity, the Cisco Nexus 7700 platform delivers the highest-capacity 10, 40, and 100 Gigabit Ethernet ports in the industry, with up to 768 native 10-Gbps ports, 384 40-Gbps ports, and 192 100-Gbps ports. This high system capacity is designed to meet the scalability requirements of the largest cloud environments.
The Cisco Nexus 7700 switches have operation and feature consistency with the existing Cisco Nexus 7000 Series Switches, using a common system architecture, the same application-specific integrated circuit (ASIC) technology, and the same proven Cisco NX-OS Software releases.
The Cisco Nexus 7700 F2e-Series module (Figure 1) is a low-latency, high-performance, high-density 10 Gigabit Ethernet module designed for the Cisco Nexus 7700 platform to deliver up to 768 wire-rate 10 Gigabit Ethernet ports in a single Cisco Nexus 7700 18-Slot Switch chassis (Table 1).

The Cisco Nexus 7700 F2e-Series module is built on a switch-on-chip (SoC) architecture, in which a single ASIC implements all the module functions, including ingress buffering, forwarding of lookup operations, management of access control lists (ACLs) and quality-of-service (QoS) tables, establishment of lossless links to fabric interfaces, and traffic load balancing through virtual output queues (VOQs). This type of design increases performance while lowering the power and cooling requirements of the module. The module delivers 720 million packets per second (mpps) of distributed Layer 2 and Layer 3 forwarding and up to 480 Gbps of data throughput. A Cisco Nexus 7700 18-Slot Switch fully populated with the Cisco Nexus 7700 F2e-Series module has the capability to deliver up to 11.5 billion packets per second (bpps) and 15.4 Tbps of switching performance.
Features and Benefits
The module protects investments with standards-based 10 Gigabit Ethernet that allows IT departments to consolidate networks based on their own unique requirements and timing:
• Each port can also be used at 1 Gigabit Ethernet speed, allowing IT departments to migrate to 10 Gigabit Ethernet according to the specific needs of their networks.
• The Cisco Nexus 7700 F2e-Series module includes classic Layer 2 and Layer 3 forwarding, powered by the proven and comprehensive Cisco NX-OS feature set. This extremely comprehensive set of Layer 2 and Layer 3 functions makes this module excellent for data center networks, in which density, performance, and continuous system operation are critical.
• The Cisco Nexus 7700 F2e-Series module is a key enabler of Cisco FabricPath. With Cisco FabricPath, organizations can build resilient, flexible, and if needed, massively scalable Layer 2 networks. Cisco FabricPath protects enterprises' investments by allowing existing spanning-tree-based deployments to be connected to a Cisco FabricPath network.
• The Cisco Nexus 7700 F2e-Series module can be used in conjunction with the Cisco Nexus 2000 Series Fabric Extenders. The Cisco Nexus 2000 Series Fabric Extenders (FEX) are designed to simplify data center architecture and operations by dramatically reducing the number of points of management.
• The Cisco Nexus 7700 F2e-Series module delivers integrated Fibre Channel over Ethernet (FCoE), greatly simplifying the network infrastructure and reducing costs by enabling the deployment of unified data center fabrics to consolidate data center traffic onto a single, general-purpose, high-performance, highly available network. With the Cisco Nexus 7700 F2e-Series module, FCoE can be deployed in director-class modular platforms for the access layer and core of converged networks.
• The virtual device context (VDC) feature helps enable the virtualization of a single physical device in one or more logical devices. Each provisioned logical device is configured and managed as if it were a separate physical device.
• The Cisco Nexus 7700 F2e-Series module offers exceptional security with integrated hardware support for:
– Configurable control-plane policing (CoPP), which protects the supervisor CPU from excessive traffic
– ACL counters and logging capability to allow administrators to see what traffic is policed
– Layer 2 to Layer 4 ACL for both IPv4 and IPv6 traffic
– Cisco TrustSec® technology, including line-rate data confidentiality, data integrity, and ACL processing for security group tags (SGTs); data confidentiality and integrity conforming to the IEEE MAC security standard (IEEE 802.1AE MACsec) is supported on a subset of ports: more specifically, ports 41 to 48 (the leftmost eight ports) on the module support the Advanced Encryption Standard (AES) cipher, using a 128-bit key
