Dell PowerSwitch S4820T Configuration Guide for the S4820T System 9.100.0 - Page 748

The following ciphers are available. • 3des-cbc • aes128-cbc • aes192-cbc • aes256-cbc • aes128-ctr • aes192-ctr • aes256-ctr The default cipher list is in the given order: aes256-ctr, aes256-cbc, aes192-ctr, aes192-cbc, aes128-ctr, aes128-cbc, 3des-cbc. Example of Configuring a Cipher List The following example shows you how to configure a cipher list. Dell(conf)#ip ssh cipher aes128-ctr aes128-cbc 3des-cbc 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.
