encrypted communication between two hosts over an unsecured network.

Privilege 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

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.
Apply 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.
