Enter public key name(must have .pub suffix):id_rsa.pub

Enter login name:auser

Password:

Public key is imported successfully.

4. Test the setup by logging in to the switch from a remote device, or by running a command remotely

using SSH.

Configuring outgoing SSH authentication

After the allowed-user is configured, the remaining setup steps must be completed by the allowed-user.

Use the following procedure to configure outgoing SSH authentication:

1. Log in to the switch as the default admin.
2. Change the allowed-user’s permissions to admin, if applicable.

switch:admin> userconfig --change username -r admin

where the username variable is the name of the user who can perform SSH public key
authentication, and who can import, export, and delete keys.

3. Set up the allowed-user by typing the following command:

switch:admin> sshutil allowuser username

where the username variable is the name of the user who can perform SSH public key
authentication, and who can import, export, and delete keys.

4. Generate a key pair for switch-to-host (outgoing) authentication by logging in to the switch as the

allowed user and entering the sshUtil genkey command.

You may enter a passphrase for additional security.

Example of generating a key pair on the switch

switch:alloweduser> sshutil genkey

Enter passphrase (empty for no passphrase):

Enter same passphrase again:

Key pair generated successfully.

5. Export the public key to the host by logging in to the switch as the allowed-user and entering the

sshUtil exportpubkey command to export the key.

Example of exporting a public key from the switch

switch:alloweduser> sshutil exportpubkey

Enter IP address:192.168.38.244

Enter remote directory:~auser/.ssh

Enter login name:auser

Password:

public key out_going.pub is exported successfully.

6. Append the public key to a remote host by logging in to the remote host, locating the directory where

authorized keys are stored, and appending the public key to the file.

You may need to refer to the host’s documentation to locate where the authorized keys are stored.

7. Test the setup by using a command that uses SCP and authentication, such as firmwareDownload

or configUpload .

Deleting public keys on the switch
