Before performing the following tasks, you must use the client software to generate an RSA key pair on
the client, save the public key in a file named key.pub, and then upload the file to the SSH server
through FTP or TFTP. For details, refer to Configure the SSH client below.
# Import the client’s public key from file key.pub and name it Switch001.
[Switch] public-key peer Switch001 import sshkey key.pub
# Specify the authentication type for user client002 as publickey, and assign the public key Switch001
to the user.
[Switch] ssh user client002 service-type stelnet authentication-type publickey assign
publickey Switch001
2) Configure the SSH client
# Generate an RSA key pair.
Run PuTTYGen.exe, select SSH-2 RSA and click Generate.

While generating the key pair, you must move the mouse continuously and keep the mouse off the
green process bar shown in Figure 1-5 . Otherwise, the process bar stops moving and the key pair
generating process will be stopped.
