Configuring Public Keys for Clients
A user public/private key pair is used to provide secure communications between an
SSH client and the switch. After generating this key pair, you must provide the user
public key to SSH clients and import the client’s public key to the switch.
Field Attributes
• Public-Key of admin/user – The public key for the adminstrator or user.
- RSA: The first field indicates the size of the public key (e.g., 1024), the second
field is the encoded public exponent (e.g., 65537), and the last string is the
encoded modulus.
- DSA: The first field indicates that the encryption method used by SSH is based
on the Digital Signature Standard (DSS). The last string is the encoded modulus.
• User Name – The user type used for the public key pair.
• Public-Key Type – The key type used to generate the user public key pair (i.e.,
public and private keys). (Range: RSA, DSA, Both: Default: RSA)
• 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.
• TFTP Server IP Address – The TFTP server IP address location for the public key
pair.
• Source File Name – The file name used for the public key pair.
• Copy Public Key – Save a copy of the public key pair.
• Delete – This button deletes the user public key process.
