Is there a way of setting up a Cisco swtich (Cisco Catalyst 3850 12 Port GE SFP IP Base - its not arrived so I don't know the IOS) to allow SSH without specifying a USERNAME
The customer currently has many switches all setup allowing TELNET using
no aaa new-model
...
line vty 0 4
exec-timeout 15 0
password ThisIsNotAPassword
login
and I want to covert them to SSH. So I'll need to change their current method of logon.
I've always used aaa new-model and so on and so whilst I don't believe its possible to use SSH without a user I want to know that this is true before I tell my customer.
I've seen some articles about using certificates but nothing specifically about this.
