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 456 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.

Associating Public Key with SSH User
Please perform the following configurations in System View.

Configuring SSH Client There are several types of SSH client software, such as PuTTY and FreeBSD. You
should first configure the client’s connection with the server. The basic
configuration tasks on the client include:
■
Specifying server IP address.
■
Selecting SSH protocol. The client supports the remote connection protocols
link Telnet, Rlogin and SSH. To set up SSH connection, you must select SSH
protocol.
■
Choosing SSH version. The Switch currently supports SSH Server 1.5, so you
have to choose 1.5 or an earlier version.
