The default cipher list is 3des-cbc,aes128-cbc,aes192-cbc,aes256-cbc,aes128-ctr,aes192-ctr,aes256-ctr
Example of Configuring a Cipher List
The following example shows you how to configure a cipher list.
Dell(conf)#ip ssh server cipher 3des-cbc aes128-cbc aes128-ctr
Secure Shell Authentication
Secure Shell (SSH) is enabled by default using the SSH Password Authentication method.
Enabling SSH Authentication by Password
Authenticate an SSH client by prompting for a password when attempting to connect to the Dell
Networking system. This setup is the simplest method of authentication and uses SSH version 1.
To enable SSH password authentication, use the following command.
• Enable SSH password authentication.
CONFIGURATION mode
ip ssh password-authentication enable
Example of Enabling SSH Password Authentication
To view your SSH configuration, use the
show ip ssh
command from EXEC Privilege mode.
Dell(conf)#ip ssh server enable
Dell(conf)#ip ssh password-authentication enable
Dell# show ip ssh

Password Authentication : enabled.
Hostbased Authentication : disabled.
RSA Authentication : disabled.
Vty Encryption HMAC Remote IP
Using RSA Authentication of SSH
The following procedure authenticates an SSH client based on an RSA key using RSA authentication. This
method uses SSH version 2.
1.
On the SSH client (Unix machine), generate an RSA key, as shown in the following example.
2.
Copy the public key
id_rsa.pub
to the Dell Networking system.
