The Cisco Catalyst 3650 supports an optional stacking module that is based on the Cisco StackWise-160 technology. StackWise-160 has a stack bandwidth of 160 Gbps. It creates a highly resilient single unified system of up to 9 switches. It also enables local switching in Cisco Catalyst 3650 Series Switches.
