SSH login command not working in Packet Tracer

[TheFox]

I am doing an exercise where I configure SSH. I believe all of the commands have been entered correctly. However, when I try to actually SSH into a device, I get a invalid input command that you can see here:  

I have attached the packet tracer file I am working on. All passwords are set to " illinois ". I should be able to log in with SSH from any device correct? I have tried from switches, routers, and PC. Will packet tracer actually allow the command? Can someone please check out the packet tracer file and tell me what gives?

Please Use ? to help out.   in this case, u need -l which needs user with SSH -l  

then, u can see what u need next with ?

SSH -l ? and so forth ... some options are mandatory while others optional

ssh -l Martin 10.1.1.1.1

Thanks MartinLo, that did the trick! For some reason using -l was not listed in my study guide.

you can always use ? when u see "invalid input detected " before or in place of ^ "carrot" sign.
