This MIB module contain a collection of managed objects that apply to network devices supporting the Cisco StackWise(TM) technology. The StackWise technology provides a method for collectively utilizing a stack of switches to create a single switching unit. The data stack is used for switching data packets and, in power stack, switches are connected by special stack power cables to share power. Moreover, stackwise is the concept for combining multiple systems to give an impression of a single system so that is why both power stack and data stack are supported by single MIB. Terminology: Stack - A collection of switches connected by the Cisco StackWise technology. Master - The switch that is managing the stack. Member - A switch in the stack that is NOT the stack master. Ring - Components that makes up the connections between the switches in order to create a stack. Stackport - A special physical connector used by the ring. It is possible for a switch have more than one stackport. SDM - Switch Database Management. Stack Power - A collection of switches connected by special stack power cables to share the power of inter-connected power supplies across all switches requiring power. Stack Power is managed by a single data stack. Jack-Jack - It is a device that provides the Power Shelf capabilities required for Stack Power on the high-end.
