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 Switches are 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 Switches 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, or 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 operational and feature consistency with the existing Cisco Nexus 7000 Series Switches, using common system architecture, the same application-specific integrated circuit (ASIC) technology, and the same proven Cisco NX-OS Software releases.
The Cisco Nexus 7700 Supervisor 2E (Supervisor 2 Enhanced) Module (Figure 1) scales the control-plane and data-plane services for the Cisco Nexus 7700 Switches in scalable data center networks. The enhanced supervisor module is designed to deliver control-plane and management functions. The supervisor controls the Layer 2 and 3 services, redundancy capabilities, configuration management, status monitoring, power and environmental management, and more. It provides centralized arbitration to the system fabric for all line cards.
The fully distributed forwarding architecture allows the supervisor to support transparent upgrades to I/O and fabric modules with greater forwarding capacity. Two supervisors are required for a fully redundant system, with one supervisor module running as the active device and the other in hot-standby mode, providing exceptional high-availability features such as stateful switchover and In-Service Software Upgrade (ISSU) on mission-critical data center-class products.
Figure 1. Cisco Nexus 7700 Supervisor 2E Module
The Cisco Nexus 7700 Supervisor 2E Module is based on a two-quad-core Intel Xeon processor with 32 GB of memory that scales the control plane by harnessing the flexibility and power of the two quad cores, offering high control-plane performance and scalability: for example, support for more virtual device contexts (VDCs) and fabric extenders.

– Spanning Tree Protocol processing
– Internet Group Management Protocol (IGMP) processing for multicast, etc.
– CPU shares to allocate and help guarantee CPU cycles for the highest-priority VDCs
Figure 2. Cisco Nexus 7700 Supervisor 2E Module Connectivity and Indicators
Table 1 summarizes the features and benefits of the Cisco Nexus 7700 Enhanced supervisor module.
Table 1. Features and Benefits
Two supervisor modules operate in active and standby modes with stateful supervisor failover to enhance total system availability.
Resilient dedicated connectivity to each fabric and I/O module slot
Dual redundant Ethernet out-of-band channels to each module and fabric provide resilience for communication between the control plane and line-card processors.
Active-active control of the flow of traffic through the switch fabric helps ensure transparent switchover with no data loss.
Virtual output queue (VOQ)
A quality-of-service (QoS)-aware lossless fabric avoids the problems associated with head-of-line blocking.
Embedded packet analyzer
An advanced integrated troubleshooting tool reduces the need for dedicated protocol analyzers and provides faster resolution of control-plane problems.
LEDs provide visible indicators of the supervisor ID, active or standby status, power management, and activity on the compact flash drive.
Using the beacon feature, the administrator can clearly identify the chassis and supervisor module.
Ports enable access to USB flash memory devices for software image loading and recovery.
Log flash memory
16 GB of internal log flash memory is available for logging.
CPU shares enable you to allocate specific amounts of the switch's CPU processing to a specific VDC. This feature enables you to prioritize VDCs and help ensure that critical VDCs have access to the CPU, and it prevents lower-priority VDCs from negatively affecting higher-priority VDCs.
Two supervisor modules are required in a Cisco Nexus 7700 switching system for high availability with active-standby redundancy, with one supervisor module operationally active, and the standby device serving as a hot backup. Both supervisors in the redundancy configuration must be of the same type.
Advanced Diagnostics and Troubleshooting Tools
Management of large-scale data center networks requires proactive management tools to verify connectivity and mechanisms for capturing and analyzing traffic. The Cisco Nexus 7700 Switches Supervisor 2E Module incorporates highly advanced analysis and debugging capabilities. The Power-On Self-Test (POST) and Cisco Generic Online Diagnostics (GOLD) provide proactive health monitoring both at startup and during system operation. The supervisor module uniquely provides a built-in packet capture and protocol-decoding tool that allows analysis of control-plane traffic to improve network planning, provide faster operation response times to events, and reduce operating costs.
