Extreme Stacking Backup Node Reboot

Extreme Stacking Backup Node Reboot

Colleagues, good afternoon . Prompt
please, there is such problem - if one of switches in a stack (master) is overloaded that the second node backup is overloaded after it through
10-15 seconds. And this in my opinion is some nonsense. Have you encountered such behavior of the stack and can it be defeated?



On the X670G2-48x and G670G2-72x stack, the license level on both switches is the same, both have master capability enabled.

Why leads you to think that stacking of these two switches is the source of your problem? What do you mean by the stack members being overloaded?
