and client can reach each other.

Configure the authentication mode and other settings.
Run the SSH client program.
SSH client
Obtain the IP address of the VLAN interface on the server.
By default, the device is enabled with the SSH server and client functions.
• On a device that serves as the SSH client, you can log in to an SSH server to perform operations on
the server.
• On a device that serves as the SSH server, you can configure the authentication mode and user level
for SSH users. By default, password authentication is adopted for SSH login, but no login password
is configured, so you cannot log in to the device through SSH by default. Before you can log in to
the device through SSH, you need to log in to the device through the console port and configure the
authentication mode, user level, and common settings.
This section includes these topics:
