Cisco Nexus 7700 M3-Series 48-Port 1/10G Ethernet Module

The Cisco Nexus® 7700 M3-Series 48-Port 1 and 10 Gigabit Ethernet Module is a versatile I/O module with a comprehensive feature set that offers wire-rate performance on each port. The module provides deep buffers and high-capacity ternary content-addressable memory (TCAM), making this module an excellent choice for building high-density, low-latency, scalable data centers.

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, which supports more than 83 terabits per second (Tbps), is the latest extension to the Cisco Nexus 7000 Series modular switches. The Cisco Nexus 7700 platform switches are operationally consistent with the existing Cisco Nexus 7000 Series switches and have a similar system architecture. The Cisco Nexus 7700 Series switches are designed using the same application-specific integrated circuit (ASIC) technology and run on the same proven NX-OS releases as the Cisco Nexus 7000 switches. Table 1 summarizes the 1 and 10 GE port density of switches in this platform.

• Onboard fabric services accelerator (FSA): The accelerator provides higher performance and greater scalability for distributed fabric services such as Bidirectional Forwarding Detection (BFD) and Cisco NetFlow.
• Layer 2-to-Layer 4 ACL for both IPv4 and IPv6 traffic
• ACL counters and logging capability to provide deeper packet visibility
• Control-Plane Policing (CoPP), which protects the supervisor CPU from excessive traffic
• Cisco TrustSec® technology and access control list (ACL) processing for security-group tags (SGTs) on all ports
• MAC Security (MACsec) at wire rate with 128- and 256-bit encryption on all ports, supporting both key agreement protocols (Security Association Protocol [SAP] and MACsec Key Agreement [MKA]) in hardware
• Virtual device context (VDC): This feature enables the virtualization of a single physical device as multiple logical devices. Each provisioned logical device is configured and managed as if it were a separate physical device.
• Advanced data center interconnect (DCI) protocols: Advanced protocols such as Cisco Overlay Transport Virtualization (OTV), Locator/ID Separation Protocol (LISP), Multiprotocol Label Switching (MPLS), and Virtual Private LAN Service (VPLS) offer customers a broad choice of technologies to transparently interconnect their data centers and to extend applications across geographically dispersed data center sites.
• Virtual Extensible LAN (VXLAN): VXLAN enables organizations to build highly scalable virtual overlay networks for virtualized environments. It also provides the architectural flexibility and agility required to scale cloud deployments with repeatable pods in different Layer 2 domains and to migrate virtual machines between servers across Layer 3 networks.
• GPRS Tunneling Protocol (GTP) Hashing: This feature leverages the advanced packet parsing capabilities of the M3 modules to provide enhanced port channel and ECMP load balancing for GTP packets.
