Cisco Nexus 7700 M3-Series - Switch - L3 - Managed - 12 X QSFP - Plug-in Module - Refurbished - For P/N: N7706-EN-B22S2E, N7706-SDA-B23S2E, N77-C7706-B33S3E-R, N77-C7710-B36S3E - N77-M312CQ-26L-RF

• 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.
• 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.
• 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 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.
• 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.
• Cisco FabricPath
  This technology enables organizations to build resilient, flexible, and massively scalable Layer 2 networks. FabricPath provides investment protection by allowing existing spanning-tree-based deployments to be connected to a FabricPath network.
• Cisco Nexus 2000 Series Fabric Extenders
  The Cisco Nexus 7700 M3-Series modules can be used with the Cisco Nexus 2000 Series Fabric Extenders. These fabric extenders are designed to simplify data center architecture and operations by dramatically reducing the number of points of management.
• Port breakout capability
  This feature allows up to 23 of the 24 physical 40 Gigabit Ethernet ports on the module to be split into 4 logical and independent 10 Gigabit Ethernet ports. Any port that is not configured for breakout remains available for establishing 40 Gigabit Ethernet links. The capability to configure the breakout mode on each port independently of any other port without the need to reload the module enhances operational simplicity. Copper or fiber breakout assemblies are required to enable the physical separation of 10 Gigabit Ethernet channels.

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 40GE port density of the switches in this platform.
