Secure Shell protocol
To ensure security, Fabric OS supports secure shell (SSH) encrypted sessions. SSH encrypts all
messages, including the client transmission of the password during login. The SSH package
contains a daemon (sshd), which runs on the switch. The daemon supports a wide variety of
encryption algorithms, such as Blowfish-Cipher block chaining (CBC) and Advanced Encryption
Standard (AES).
NOTE
To maintain a secure network, you should avoid using Telnet or any other unprotected application
when you are working on the switch.
Commands that require a secure login channel must originate from an SSH session. If you start an
SSH session, and then use the login command to start a nested SSH session, commands that
require a secure channel will be rejected.
Fabric OS supports OpenSSH protocol v2.0 (ssh2). For more information on SSH, refer to the SSH
IETF website:

SSH public key authentication
OpenSSH public key authentication provides password-less logins, known as SSH authentication,
that uses public and private key pairs for incoming and outgoing authentication. This feature allows
only one
allowed-user
to be configured to utilize outgoing OpenSSH public key authentication.Any
admin user can perform incoming Open SSH public key authentication. Using OpenSSH RSA and
