Create an SSH user, and 
specify an authentication type 
for it 

ssh user username 
authentication-type { all | 
password | password-publickey 
| publickey }

are used and different 
authentication types are 
specified, the authentication 
type specified with the ssh 
user authentication-type 
command takes precedence. 

 

z 

For password authentication type, the username argument must be consistent with the valid user 

name defined in AAA; for publickey authentication, the username argument is the SSH local user 

name, so that there is no need to configure a local user in AAA. 

z 

If the default authentication type for SSH users is password and local AAA authentication is 

adopted, you need not use the ssh user command to create an SSH user. Instead, you can use 

the local-user command to create a user name and its password and then set the service type of 

the user to SSH. 

z 

If the default authentication type for SSH users is password and remote authentication (RADIUS 

authentication, for example) is adopted, you need not use the ssh user command to create an 

SSH user, because it is created on the remote server. And the user can use its username and 

password configured on the remote server to access the network. 

z 

Under the publickey authentication mode, the level of commands available to a logged-in SSH 

user can be configured using the user privilege level command on the server, and all the users 

with this authentication mode will enjoy this level. 

z 

Under the password  or  password-publickey  authentication mode, the level of commands 

available to a logged-in SSH user is determined by the AAA scheme. Meanwhile, for different 

users, the available levels of commands are also different.  

z 

Under the all  authentication mode, the level of commands available to a logged-in SSH user is 

determined by the actual authentication method used for the user.  

 

At present, the switch supports two service types for SSH: stelnet (secure Telnet) and SFTP.  

z 

The secure Telnet service is a basic application of SSH protocol. It uses the secure channel of 

SSH to provide remote login. 

z 

The SFTP service is an extended application of SSH protocol. It uses the secure channel of SSH 

to perform remote FTP operations. 

Follow these steps to specify the service type for an SSH user:
