Entering Public Key Edit View and Editing Public Key
You can enter the public key edit view and edit the client public key.
This operation is only available for the SSH users using RSA authentication. At the
Switch, you configure the RSA public key of the client, while at the client, you
specify the RSA private key which corresponds to the RSA public key.
This operation will fail if you configure password authentication for the SSH user.
Perform the following configurations in System View.
Table 333 Configuring Public Key
When entering the public key edit view with the
rsa peer-public-key
command, you can begin editing the public key with the
public-key-code begin
command. You can key in a blank space between characters, since the system can
remove the blank space automatically. But the public key should be composed of
hexadecimal characters. Terminate public key editing and save the result with the
public-key-code end
command. Validity check comes before saving: the public
key editing fails if the key contains invalid characters.
Perform the following configurations in the Public Key View.
