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
telnet file transfers. The G250/G350 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 G250/G350, enter
show ip ssh
