switch for the user to be able to log in using the public key authentication mechanism. If the users public key does not exist on
the switch, SSH will revert to the interactive password authentication mechanism to complete authentication.

users on the User Accounts page.
User Key Type The type of public key to upload.
RSA: The switch accepts a RSA version 1 encrypted public key.
DSA: The switch accepts a DSA version 2 encrypted public key. The SSH server uses RSA or DSA for key
exchange when the client first establishes a connection with the switch, and then negotiates with the client to select
either DES (56-bit) or 3DES (168-bit) for data encryption. The switch uses only RSA Version 1 for SSHv1.5 clients
and DSA Version 2 for SSHv2 clients.
TFTP Server IP Address The IP address of the TFTP server that contains the public key file you wish to import.
Source File Name The public key file to upload.
