Configuration procedure

1 Generate a local RSA key pair.

<S4200G>system-view

[4200G] rsa local-key-pair create

If the local RSA key pair has been generated in previous operations, skip this step.

2 Set authentication type.

Settings for the two authentication types are described respectively in the following:

■ Password authentication

■ Set AAA authentication on the user interfaces.

[4200G] user-interface vty 0 4

[4200G-ui-vty0-4] authentication-mode scheme

Set the user interfaces to support SSH.

[4200G-ui-vty0-4] protocol inbound ssh

Configure the login protocol for the clinet001 user as SSH and authentication type as

password.

[4200G] local-user client001

[4200G-luser-client001] password simple abc

[4200G-luser-client001] service-type ssh

[4200G-luser-client001] quit

[4200G] ssh user client001 authentication-type password

Select the default SSH authentication timeout time and authentication retry times.

After these settings, run the SSH2.0-supported client software on other hosts

connected to the switch. Log in to the switch using user name client001 and

password abc.

■ RSA public key authentication
