Cisco StackWise is a technology offered by Cisco Systems that allows for up to nine Catalyst switch 3750 series switches to operate as though one 32-Gbit/s switch. This allows for greater resiliency, and performance.

One switch from the stack will act as the master switch. The master switch will maintain the stack and allow you to configure and monitor the whole stack as though one via a single console.

If one switch fails the remaining switches will continue to operate by looping back any information that would normally traverse the failed switch, effectively bypassing it. If the master switch fails, the next switch in the stack will automatically take over as master. This feature means greater redundancy, as one switch's failure will not bring about a failure of the entire stack.
