Hello, what type of authentication do you use : local or aaa ? Maybe it is an AAA authentication problem, because the SSH configuration seems OK for me.

P.S : try to connect from another terminal or from a router.

Ur reply was very usefull. I tried from a router to that router. It is working.

then the problem identified in firewall settings.

Hi,

for ssh you must use a username/password so  as previous poster said you must have a user on local database or on a tacacs+/radius server

and use login local command if username on local router.

Thanks All,

The problem was with firewall settings. The ssh protocol was blocked in my firewall.
