Don't type here any '?' or 'tab' things for autocompletion here, its better copy that command from the notepad(!). And yes just copy of the code from the publuc key, because terminal my think that ? or any other symbols are the part of the public key and will show you an error. 

rsa peer-public-key KEY_NAME encoding-type pem

 public-key-code begin

  ----- BEGIN SSH2 PUBLIC KEY -----


 ----- END SSH2 PUBLIC KEY -----

 public-key-code end

peer-public-key end



 local-user ANY_NAME service-type ssh


user-interface vty 0 4

 user privilege level 15 (important to get priveleges for that username)


stelnet server enable

ssh user ANY_NAME authentication-type rsa

ssh user ANY_NAME assign rsa-key KEY_NAME

ssh user ANY_NAME service-type stelnet

4.0 Using keys

for putty:

ssh>auth>path to a private key

connection>data>auto-login username 'ANY_NAME' (important)

for securecrt:

tools->manage agent keys->add a private key

in session ->connection>ssh2>enable only 'public key' or put it at the top

Username:  'ANY_NAME' (important)
