not that I'm able to help you with the CoS configuration... but I noticed that you uploaded your entire Cisco switch configuration including cisco 7 passwords. These encryptions are easily reversible so now you password for login and tacacs key can be read by anyone.
I would recommend you to remove your attachment and upload a new one only containing the relevant parts of the configuration.
