I can SSH into my switch, but can't login.

So answer me this. I have a brocade FastIron WS 648G, and I have enabled SSH on the switch. When I SSH into the switch using putty. Everything works, until I try to log in. It gives me the access denied error. I'm guessing I have to give the switch user access to SSH? New to Brocade, so bear with me!

Here are the commands I used so far:

enable

config t

crypto key generate

ip ssh authentication-retries 5

ip ssh key-size 512

ip ssh password-authentication yes

ip ssh timeout ssh timeout 30
