NTPv4 AES128CMAC authentication test procedure

Hi,
Can you please share steps to validate NTPv4 AES128CMAC authentication?

I have ported the code base for NTPv4 and able to validate for Md5 and Sha1 symmetric key authentication.
But in same way not able validate for AES128CMAC symmetric key.
Can you please share the steps to validate it ?
if possible let me know both side (server and client) setting for this AES128CMAC key with example.

Thanks & regards
Shamsher

Seems like an odd question; you're skilled enough as a programmer to port fairly complex code, but only part of it?

And you provide nothing in the way of details; version/distro of Linux, what programming language, what error(s)/message(s) you get, or show us ANYTHING that you've done or tried on your own. Putting "how to validate AES128CMAC symmetric key" into a search-engine pulls up lots...we aren't going to look up samples for you, or write your code for you.
