I had to configure a 5660 on a test bench and then installed. I notice that when trying to SSH in I get a login prompt and after entering my local username and password I get a frozen connection. I do not have any ACL's set up yet.
Do I need to generate RSA Keys on a 5660 to allow SSH?
Make sure you set up a line ssh.
line ssh 0 4
login local-userlist
no shutdown
If you want to limit who can ssh to your 5660, you can set up an access list.
