Parameters
username: Specifies an SSH username, a case-sensitive string of 1 to 80 characters. If the username
contains ISP domain name, the form is pureusername@domain.
service-type: Specifies a service type for an SSH user:
• all: Specifies Stelnet, SFTP, and SCP.
• scp: Specifies the service type as SCP.
• sftp: Specifies the service type as SFTP.
• stelnet: Specifies the service type of Stelnet.
authentication-type: Specifies an authentication method for an SSH user:
• password: Specifies password authentication. This authentication method features easy and fast
encryption, but it is vulnerable. It can work with AAA to implement user authentication,
authorization, and accounting.
• any: Specifies either password authentication or publickey authentication.
• password-publickey: Specifies both password authentication and publickey authentication
(featuring higher security) if the client runs SSH2, and specifies either type of authentication if the
client runs SSH1.
• publickey: Specifies publickey authentication. This authentication method has complicated and
slow encryption, but it provides strong authentication that can defend against brute-force attacks.
This authentication method is easy to use. If this method is configured, the authentication process
completes automatically without the need of entering any password.
assign publickey keyname: Assigns an existing host public key to an SSH user. The keyname argument
is a string of 1 to 64 characters.
Usage guidelines
To configure an SSH user that uses publickey authentication, you must create a local user that has the
same username as the SSH user to assign the working directory and user role.
To configure an SSH user that uses password authentication, you must configure a local user account by
using the local-user command for local authentication, or configure an SSH user account on an
authentication server, for example, a RADIUS server, for remote authentication. For password-only SSH
users, you do not need to execute this command to configure them unless you want to use the display ssh
