Product Information
The Cisco Nexus 7700 Supervisor 2E (Supervisor 2 Enhanced) Module 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.
- 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 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. - Front-panel LEDs
LEDs provide visible indicators of the supervisor ID, active or standby status, power management, and activity on the compact flash drive. - Identification 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. - CPU shares
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.
