The following solutions apply only to the stack of CE8800, CE7800, CE6800, and CE5800 series switches instead of the stack of CE12800 and CE12800E series switches.

In Figure 1, two switches set up a stack using 10GE ports. It is required that 10GE ports be switched to 40GE ports without interrupting services. Perform the following operations to meet this requirement:

1. Create a new logical stack port and add 40GE ports in the created logical stack port. Connect the 40GE ports using cables to set up a stack in a ring topology.

2. Remove cables of 10GE ports and delete the stack configuration of these ports.

Figure 1

If the stack has been set up in a ring topology, remove 10GE ports from the logical stack port, remove their cables, add 40GE ports in the logical stack port, and then connect the 40GE ports using cables.
