Product Overview

The second-generation Cisco Nexus® 7000 Supervisor Modules scale the control-plane and data-plane services for the Cisco Nexus 7000 Series Switches in scalable data center networks. The second-generation Cisco Nexus 7000 Series Supervisor Modules come in two versions: Supervisor2 (Sup2) and Supervisor2 Enhanced (Sup2E) (see Figure 1).

The Cisco Nexus 7000 Switches comprise a modular data center-class product line designed for highly scalable 10 Gigabit Ethernet networks with a fabric architecture that scales beyond 15 terabits per second (Tbps). Designed to meet the requirements of the most mission-critical data centers, it delivers continuous system operation and virtualized, pervasive services. The Cisco Nexus 7000 Switches is based on a proven operating system, with enhanced features to deliver real-time system upgrades with exceptional manageability and serviceability. Its innovative unified fabric design is specifically built to support consolidation of IP and storage networks on a single lossless Ethernet fabric.

The Cisco Nexus 7000 Supervisor Modules are designed to deliver scalable control-plane and management functions for the Cisco Nexus 7000 chassis. 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 in data center-class products.

Features and Benefits

The second-generation Cisco Nexus 7000 Supervisor Modules deliver a comprehensive set of features to address the needs of the most demanding data center deployments:

Continuous system operation

- Active and standby supervisors

- Segmented and redundant out-of-band provisioning and management paths

- Virtualization of the management plane

- Integrated diagnostics and protocol decoding with an embedded control-plane packet analyzer

Upgradeable architecture

- No hardware or software forwarding

- Independent supervisor and fabric modules in a distributed architecture, enabling independent upgrades of supervisor and fabric modules

- Transparent upgrade capacity and capability; designed to support high-density 10, 40 and 100 Gigabit Ethernet

Superior operating efficiency

- System locator and beacon LEDs for simplified operations

- On-board failure logging (OBFL) flash memory

Control-plane and virtualization features such as:

- Virtual device contexts (VDCs)

- Fabric extender control plane

- Cisco® Overlay Transport Virtualization (OTV) control plane

- Layer 3 protocol learning

- Spanning Tree Protocol processing

- Internet Group Management Protocol (IGMP) processing for multicast, etc.

- CPU shares to allocate and guarantee CPU for the highest-priority VDCs

Cisco Nexus 7000 Supervisor2 Enhanced Module

The Cisco Nexus 7000 Series Sup2E Module (Figure 2) 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. With four times the CPU and memory power of the first-generation Cisco Nexus 7000 Supervisor1 (Sup1) Module, the Sup2E module offers the highest control-plane performance and scalability of the modules: for example, supporting more VDCs and fabric extenders.

Cisco Nexus 7000 Supervisor2 Module

The Cisco Nexus 7000 Series Supervisor2 (Sup2) Module (Figure 3) is based on a quad-core Intel Xeon processor with 12 GB of memory and scales the control plane by harnessing the flexibility and power of the quad cores. A faster CPU and expanded memory compared to the first-generation Sup1 module enable better control-plane performance and an enhanced user experience.

Table 1 summarizes the features and benefits of the Cisco Nexus 7000 Supervisor Modules.

Table 1. Features and Benefits



High availability

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.

Centralized arbiter

Active-active control of the flow of traffic through the switch fabric helps ensure transparent switchover with no losses.

Virtual output queuing

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.

Front-panel LEDs

LEDs provide visible indication of the supervisor ID, active or standby status, power management, and activity on the compact flash drive.

Identification (ID) LED

Using the beacon feature, the administrator can clearly identify the chassis and supervisor module.

USB ports

Ports enable access to USB flash memory devices for software image loading and recovery.

Log and expansion flash memory

Removable devices can be used for logging and software images.

CPU shares

CPU shares enable you to allocate specific amounts of the switch’s CPU 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.

Supervisor Redundancy

Two supervisor modules are required in a Cisco Nexus 7000 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 7000 Supervisor Modules incorporate 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.
