Secure Shell or SSH is a network protocol that enables data to be exchanged on a
secure channel between an SSH client (in this case, the device) and an SSH
server.
SSH client helps the user manage a network composed of one or more switches
in which various system files are stored on a central SSH server. When
configuration files are transferred over a network, Secure Copy (SCP), which is an
application that utilizes the SSH protocol, ensures that sensitive data, such as
username/password cannot be intercepted.
Secure Copy (SCP) is used to securely transfer firmware, boot image,
configuration files, language files, and log files from a central SCP server to a
device.
With respect to SSH, the SCP running on the device is an SSH client application
and the SCP server is a SSH server application.
