This is my configuration on extreme switches

Hi Siva, I guess during configuration you may have configured the same MAC address for both the stacks which is causing this issue. please use the below command so that the MAC address will get configured automatically. "configure stacking mac-address" Please note that you need to reboot the stack once the command is executed. I hope you will not see the reported issue once you do the above.

Hi Siva, Can you share the "show switch" output from both the switches please? The last one you posted was "show conf" i am looking for the "show switch" output from both the switches and see what MAC address they have....

I have to change the cable's and change ports on both Cisco switch and extreme switch but still experiencing the same issue.

At this stage, I think extreme switch are not the good one. šŸ˜ž
