42.5 SSH Overview
Unlike Telnet or FTP, which transmit data in clear text, SSH (Secure Shell) is a secure communication
protocol that combines authentication and data encryption to provide secure encrypted
communication between two hosts over an unsecured network.

42.6 How SSH works
The following table summarizes how a secure connection is established between two remote hosts.
Chapter 42 Access Control
DESCRIPTION
Type the privilege level for this user. At the time of writing, users may have a privilege level
of 0, 3, 13, or 14 representing different configuration rights as shown below.
•
0 - Display basic system information.
•
3 - Display configuration or status.
•
13 - Configure features except for login accounts, SNMP user accounts, the
authentication method sequence and authorization settings, multiple logins,
administrator and enable passwords, and configuration information display.
•
14 - Configure login accounts, SNMP user accounts, the authentication method
sequence and authorization settings, multiple logins, and administrator and enable
passwords, and display configuration information.
Users can run command lines if the session's privilege level is greater than or equal to the
command's privilege level. The session privilege initially comes from the privilege of the
login account. For example, if the user has a privilege of 5, he/she can run commands that
requires privilege level of 5 or less but not more.
Click Apply to save your changes to the Switch's run-time memory. The Switch loses these
changes if it is turned off or loses power, so use the Save link on the top navigation panel to
save your changes to the non-volatile memory when you are done configuring.
Click Cancel to begin configuring this screen afresh.
