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
