Now, the Cisco 3750-X series is the more popular one. Both Cisco 3750 and 3750-X series are Campus LAN Access Switches. And the Cisco 3750 product line consists of non-blocking switches which support Jumbo frames, flow control and are easy to build up and expand a pay as you grow infrastructure. The Cisco Catalyst 3750-E and Catalyst 3750-X will run StackWise Plus when connected to a stack of all Cisco Catalyst 3750-E and Catalyst 3750-X switches, while it will run StackWise if there is one or more Cisco Catalyst 3750 in the stack.

Cisco 3750-E and 3750-X StackWise Plus and 3750 StackWise switches can be combined in the same stack. When this happens, the Cisco Catalyst 3750-E, or Catalyst 3750-Xswitches negotiate from StackWise Plus mode down to StackWise mode. That is, they no longer perform destination stripping. However, the Cisco Catalyst 3750-E and the Catalyst 3750-X will retain its ability to perform local switching. More…
