# Create an SSH user client002 with the authentication method publickey, and assign the public
key switchkey to the user.
[SwitchB] ssh user client002 service-type stelnet authentication-type publickey
assign publickey switchkey
# Create a local device management user client002 with the service type ssh and the user role
network-admin.
[SwitchB] local-user client002 class manage
[SwitchB-luser-manage-client002] service-type ssh

3. Establish an SSH connection to the Stelnet server 192.168.1.40.
ssh2 192.168.1.40
Username: client002
The server is not authenticated. Continue? [Y/N]:y
Do you want to save the server public key? [Y/N]:n
You can log in to Router B successfully for the first time without configuring its host public key,
because the client supports the first authentication by default.

SFTP configuration examples
Unless otherwise noted, devices in the configuration examples are in non-FIPS mode.
If you configure an SFTP server in FIPS mode, follow these guidelines:
• The modulus length of the key pair must be 2048 bits.
• Do not generate a DSA key pair on the SFTP server. Only RSA key pairs are supported.

Network requirements
As shown in
902H
Figure 59 , you can log in to the switch through the SFTP client that runs on the host and are
assigned the user role network-admin to execute file management and transfer operations. The switch
acts as the SFTP server and uses password authentication. The username and password of the client are
saved on the switch.
