Secure Shell (SSH) protocol is a network protocol that enables secure data communication between two computers over an insecure network. SSH accomplishes this by creating a transparent, encrypted channel between the local and remote devices. With the remote shell, SSH provides secure file transfer between the local and remote devices. SSH is used for Secure Copy (SCP) file transfers. Branch Gateway supports three concurrent SSH users.

An SSH session can be established by password authentication. To determine the means by which an SSH session has been established on your Branch Gateway, enter show ip ssh.

Use the ssh-server-configuration CLI command to configure SSH ciphers, MACs, and key exchange algorithms. For more details on SSH-server configuration, see Avaya Branch Gateway G430 CLI Reference guide.
