Configuration procedure

1 Generate a local RSA key pair.

<SW7750> system-view

[SW7750] rsa local-key-pair create

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

here.

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.

[SW7750] user-interface vty 0 4

[SW7750-ui-vty0-4] authentication-mode scheme

# Set the user interfaces to support SSH.

[SW7750-ui-vty0-4] protocol inbound ssh

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

as password.

[SW7750] local-user client001

[SW7750-luser-client001] password simple abc

[SW7750-luser-client001] service-type ssh

[SW7750-luser-client001] quit

[SW7750] 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 username client001 and

password abc.

■ RSA public key authentication

# Set AAA authentication on the user interfaces.

[SW7750] user-interface vty 0 4

[SW7750-ui-vty0-4] authentication-mode scheme

# Set the user interfaces to support SSH.
