Recently noticed something in the config file of a stack of 3750s that isn't in any of our other stacks. At the top of the config file is a long series of mls qos commands. We do not use qos. Wondering how they got in there and how to get them out if not needed. We do use Cisco CNA to manage the 3750s. There is also a certificate section in the config file that I never saw before. Was that added by CNA?
If you have enabled smart ports using the CNA then yes, these commands are added by CNA.
The only way which i know to remove these are via using telnet in the config mode and add no in front of each command.
By the way leaving these commands will not do any harm except the config becoms very large.
