Cisco catalyst 2960g interfaces going up and down

i have a cisco catalyst 2960g and for some reason out of the blue, some interfaces go down and then up. It started doing it after a power cycle.

does anyone have an idea of what is causing this?

Cisco catalyst 2960g interfaces going up and down

David,

Just to let you know, I´m facing the same problem.

But I can´t say it that happened after the power cycle, because my stack is brand new.

Weird is the fact that I have replaced the switches of the whole building and only the 10th floor is having this issue.

Note: They are all Cisco Catalyst 2960 with the IOS version 15.0(1)SE2 - image C2960S-UNIVERSALK9-M

Regards Kleber
