SummitStack™ allows multiple physical switches to be connected and managed as a single unit with a single IP address. This reduces complexity and enables easier management, while providing a flexible way to increase density, capacity and port configuration choices, while controlling initial capital expenditure.
SummitStack stacking technology allows customers to physically connect up to eight individual Summit® X250e, X440, X450a, X450e, X460, X480, X650, X670 or E4G 400 switches together as a single logical unit. This logical unit reduces the management overhead of fixed configuration switches by behaving as a single switch with a single IP address and a single point of authentication.
In ExtremeXOS®, the Extreme Networks edge-to-core modular operating system, a stack is controlled by a master switch, called the master. The master switch runs the full-featured version of ExtremeXOS and is responsible for maintaining all of the software tables for all the switches in the stack. There can only be one master switch in a stack of switches. All switches in the stack, including the master switch, are called nodes.
