Use only QSFP transceivers and QSFP cables (separately purchased) to connect stacking ports as follows:
1Insert a QSFP cable in the bottom stacking port on the rightmost switch.
2Connect the upper stacking port on the next switch to the left.
3Continue connecting each switch to the next in this way until you reach the leftmost switch in the stack.
4On the leftmost switch, connect the bottom stacking port to the upper stacking port on the rightmost switch to create a loop.
NOTE: The resulting ring topology allows the entire stack to function as a single switch with resilient
If you do not connect the leftmost switch to the rightmost switch (Step 4), the stack operates in a

After you attach the QSFP+ cables in a stack of MXL 10/40GbE Switches, to configure and bring up the stack, follow these steps:
1Connect the terminal to the console port on an MXL 10/40GbE Switch. Enter the following commands to access the CLI and configure the two 40GbE ports on the base module for stacking mode:
