Hi Kaleb, thank you once again for you support.
we have taken the tcpdump and have analysed and are in process of understanding the same more.
For your reference kindly find the same as from the link :
https://drive.google.com/drive/folders/1bKqlT7wO0gf9mVHyfsrAeZQudtVWnR_B?usp=sharing

it has "tar.gz" directory which will have tcpdump of both the nodes nfsnode1 and ndsnode2.
