"security ssh" configuration

Hi,

a customer wrote to me that the NetApp supports some weak ssh MAC and Encryption algorithms or Cyphers.

So i tested with "security ssh remove" to remove all with CBC, SHA1 und MD5.

I tested the access after that commnds and got no problems.

But now, one week later i cant login via SSH to the NetApp, i got only "Remote side unexpectedly closed network connection".

So i inserted all what i remved again, but i still can't login.

When it takes up to a week to get active after removing, how log does it take to get active after inserting again?

Is here a commend to restart the SSH?

I'm using ONTAP 9.8P1.

Kind regards

Stefan
