Configure Switch B
# Create a VLAN interface on the device and assign an IP address for it to serve as the destination of
the client.
[device] interface vlan-interface 1
[device-Vlan-interface1] ip address 10.165.87.136 255.255.255.0
[device-Vlan-interface1] quit
# Generate RSA and DSA key pairs.
[device] public-key local create rsa
[device] public-key local create dsa
# Set AAA authentication on user interfaces.
[device] user-interface vty 0 4
[device-ui-vty0-4] authentication-mode scheme
# Configure the user interfaces to support SSH.
[device-ui-vty0-4] protocol inbound ssh
# Set the user command privilege level to 3.
[device-ui-vty0-4] user privilege level 3
[device-ui-vty0-4] quit
# Specify the authentication type for user client001 as publickey.
[device] ssh user client001 authentication-type publickey
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
