SSH Client Configuration
Example
Network requirements
As shown in Figure 203,
■
Switch A serves as an SSH client and uses the username of client001 and IP
address of 10.1.1.2/24.
■
Switch B serves as an SSH server, with its IP address 10.1.1.3/24.
■
RSA authentication method is adopted to enhance the security.
■
The SSH client authenticates the SSH server to ensure the validity of the SSH
server.

Configuration procedure
1 Configure Switch B (SSH server)
# Create a VLAN interface on the switch and assign it an IP address, which the SSH
client will use as the destination for SSH connection.
