Hey,
Please tell me the following is not normal:
1) Pubkey auth is enabled and password auth disabled.
2) I am not using any private key at all! (no ssh -i "private_key" here)
3) I can login with the password only.

I did not find a way w/o expect for the S-Series EOS (used on the 7100 as well), see https://community.extremenetworks.com/extreme/topics/connectionproblems-with-plink-putty-for-command... 

Oups, id_rsa is the default private key file used by ssh. Mea culpa.
However this still does not solve my problem:
root@nms:~/.ssh$ ssh rw@1.2.3.4 show conf
Write failed: Broken pipe
How to run commands "unattended"? (Without using expect!)

I've fixed the formatting in your post, I know it's quirky. It works well if you click the button before pasting in your text. Rather than unselecting the button when done, just click elsewhere to move your cursor out of the area.
