High availability
This supervisor module operates 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.
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.
