There are a couple of issues here.

I am under closed WP under 2171(2 years) and 2283(1.5 Years).
If CIC is asking you to explain why you changed NOCs, then it probably appears to them that your job did not match the NOC code on your work permit. Therefore you would have performed "unauthorized" work which would put the application in doubt. Do you have a satisfactory explanation that you could give them?

I kept letter saying that I am currently working with employer but did not provide any employment letter stating roles and responsibilities instead I wrote covering letter with roles and resp.
Now CIC asking about all employment letters with employ roles and responsibilities given by Employer. Recently I got all letters from employer. Which letters do i need to submit either 2283 or 2171 letters?
I applied for 2281 but CIC asking all employment letters. so I provide all employment letter, will it problem or any issues. Please suggest me??
You need to submit reference letters (written by your employer this time, and meeting the requirements in the Document Checklist) for each job that you claimed as part of your work experience (Schedule 8 form). If you claimed both the NOC 2171 and the NOC 2283 jobs as part of your work experience, then submit both letters. If you only claimed NOC 2283, then submit only the NOC 2283 one.
I'm not sure what you mean by "applied for 2281", do you mean you applied for a job? In any case, if you didn't claim a job on your Schedule 8 form then you do not need to provide a reference letter for it.
