Before doing the following steps, you must first generate a DSA key pair on the client and save the key

pair in a file named Switch001, and then upload the file to the SSH server through FTP or TFTP. For

details, refer to the following “Configure Switch A”.

# Import the client’s public key file Switch001 and name the public key as Switch001.

[device] public-key peer Switch001 import sshkey Switch001

# Assign public key Switch001 to user client001

[device] ssh user client001 assign rsa-key Switch001

# Export the generated DSA host public key pair to a file named Switch002.

[device] public-key local export dsa ssh2 Switch002

When first-time authentication is not supported, you must first generate a DSA key pair on the server

and save the key pair in a file named Switch002, and then upload the file to the SSH client through FTP

or TFTP.

Configure Switch A

# Create a VLAN interface on the device and assign an IP address, which serves as the SSH client’s

address in an SSH connection.
