SUMMIT VIRTUAL CHASSIS

The Summit Virtual Chassis is an ultra-high performance, low-cost external backplane that connects up to eight stacked or distributed Summit switches into one cohesive system.

Features of the Summit Virtual Chassis include the following:

•Increased port density

•Policy-based Quality of Service (QoS)

•Load-sharing links

•Extensive fault-tolerant capabilities

—Redundant power supplies

—Hot-swappable switches

•How-swappable virtual chassis

—Environmental sensors

The Summit Virtual Chassis has eight SummitLink ports. A SummitLink port is a proprietary backplane channel used to connect Summit switches to the Summit Virtual Chassis.

For detailed information about the Summit Virtual Chassis, refer to the Summit Virtual Chassis Design and Installation Guide.
