SSH on Nexus 7000 doesn't work

[lorenzbauer]

I tried to connect to my Nexus 7k using ssh (which works), but I only want the connection to work with an explicit key.

This is my config:

ssh key rsa 4096

feature ssh

username admin sshkey SSH_KEY

But now I can still ssh to my Nexus from every device, why does this work.

• You can configure your device for either SSH authentication using an X.509 certificate or SSH authentication using a public key certificate but not both. If either of them is configured and the authentication fails, you are prompted for a password.

follow below guide :

check the logs if all are configured correctly on the switch.
