Importing
User Public Keys
Use the Security > SSH (Configure User Key - Copy) page to upload a user’s public
key to the switch. This public key must be stored on the switch for the user to be
able to log in using the public key authentication mechanism. If the user’s public
key does not exist on the switch, SSH will revert to the interactive password
authentication mechanism to complete authentication.
Parameters
These parameters are displayed:
◆ User Name – This drop-down box selects the user who’s public key you wish to
manage. Note that you must first create users on the User Accounts page (see
“Configuring User Accounts” on page 265).
◆ 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.
