Before performing the following tasks, you must generate a DSA public key pair
(using the client software) on the client, save the key pair in a file named key.pub,
and then upload the file to the SSH server through FTP or TFTP. For details, refer to
"Configuring the Device as an SSH Client" on page 1115.
# Import the remote public key pair from the file "key.pub".
[SwitchB] public-key peer Switch001 import sshkey key.pub
# Specify the authentication type for user "client002" as publickey, and assign the
public key "Switch001" for the user.
2 Configure the SSH client

After generating a key pair on a client, you need to transmit the saved public key
file to the server through FTP or TFTP and have the configuration on the server
done before continuing configuration of the client.
# Establish an SSH connection to the server (10.165.87.136).
<SwitchA> ssh2 10.165.87.136
Username: client002
