Cisco IOS upgrade to 15.0 bugs

If you recently upgraded Cisco Catalyst to IOS ver. 15.0(1)SE or 15.0(2)SE2 upon boot-up you can see follow warning message:

%DC-4-FILE_OPEN_WARNING: Not able to open flash:/dc_profile_dir/dc_default_profiles.txt

According to Cisco support it is “cosmetic bug” and it can be fixed with steps:

#mkdir flash:/dc_profile_dir
#cd flash:/c3560e-universalk9-mz.150-2.SE2
#copy flash:/c3560e-universalk9-mz.150-2.SE2/dc_default_profiles.txt flash:/dc_profile_dir/dc_default_profiles.txt
#cd
#cd flash:/dc_profile_dir
#dir

Another common warning you can see

Warning: The CLI will be deprecated soon
'enable secret 5 $1$XZXZHGAFZMIQmHGAFf0'

Newer passwords are using SHA256 hashing instead of MD5, it means you have to regenerate password again. The MD5 hashing will be deprecated soon.
