I was trying to ssh to a switch from an open putty session on my current switch but I just typed "ssh x.x.x.x" and all I got was a password prompt. When I entered my password it was not accepted. I tried several times.
My TACACS account was locked out.
I should have been typing "ssh -l my_username x.x.x.x" pressing enter and then entering my TACACS password.
My question is how did TACACS know to lock out my account if I was not putting my username in the ssh command?
And if TACACS did know my username then why would it not accept my password?
