I takes between 5 to 10 seconds until the SSH Login window appear, if I connect by SSH to the switch. I have the version 21.1.3.7 on the switches X440G2-48p-10G4 running. Do you have any idea, whats the reason for this?
Thanks for your replies. I checked DNS. But it's much faster by telnet, so in this case this seems to be a SSH problem, and not a DNS. And yes, I saved the key.
