SSH protocol support

Secure Shell (SSH) protocol is a security protocol that enables you to establish 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 the
remote shell, SSH provides secure file transfer between the local and remote devices. SSH is
used for SCP file transfers. The Branch Gateway supports two concurrent SSH users.
Establishing an SSH session can be done by RSA authentication, or password authentication.
To determine which of these ways is used on your Branch Gateway, enter show ip ssh.
Note:
SSH supports IPv4 and IPv6.
