In public key authentication, you can use either RSA or DSA public key. Here takes the DSA public key
as an example.
z Configure Switch B
# Create a VLAN interface on the switch and assign an IP address, which the SSH client will use as the
destination for SSH connection.
system-view
[SwitchB] interface vlan-interface 1
[SwitchB-Vlan-interface1] ip address 10.165.87.136 255.255.255.0
[SwitchB-Vlan-interface1] quit
Generating the RSA and DSA key pairs on the server is prerequisite to SSH login.
# Generate RSA and DSA key pairs.
[SwitchB] public-key local create rsa
[SwitchB] public-key local create dsa
# Set the authentication mode for the user interfaces to AAA.
[SwitchB] user-interface vty 0 4
[SwitchB-ui-vty0-4] authentication-mode scheme
# Enable the user interfaces to support SSH.
[SwitchB-ui-vty0-4] protocol inbound ssh
# Set the user command privilege level to 3.
[SwitchB-ui-vty0-4] user privilege level 3
[SwitchB-ui-vty0-4] quit
# Specify the authentication type of user client001 as publickey.
[SwitchB] ssh user client001 authentication-type publickey
Before doing the following steps, you must first generate a DSA public 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 “Configure Switch A”.
# Import the client public key pair named Switch001 from the file Switch001.
[SwitchB] public-key peer Switch001 import sshkey Switch001
