SSH Protocol Support

Introduction to SSH

SSH (Secure Shell) protocol is a security protocol that enables establishing a remote session over a secured tunnel, also called a remote shell. SSH accomplishes this by creating a transparent encrypted channel between the local and remote devices. In addition to remote shell, SSH also provides secure file transfer between the local and remote devices.

SSH uses password authentication.

A maximum of two SSH sessions can be active per router module in the stack, with
