Configuration procedure
Configure Switch B
# Create a VLAN interface on the switch and assign an IP address for it to serve as the destination of
the client.
<SwitchB> 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 key pair on the server is prerequisite to SSH login.
# Generate RSA key pair.
[SwitchB] public-key local create rsa
# Set AAA authentication on user interfaces.
[SwitchB] user-interface vty 0 4
[SwitchB-ui-vty0-4] authentication-mode scheme
# Configure 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 for user client001 as publickey.
[SwitchB] ssh user client001 authentication-type publickey
Before doing the following steps, you must first generate a RSA 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".
