Dell PowerSwitch S4820T Configuration Guide for the S4820T System 9.100.0 - Page 731

• Privilege level 1 - is the default level for EXEC mode. At this level, you can interact with the router, for example, view some show commands and Telnet and ping to test connectivity, but you cannot configure the router. This level is often called the "user" level. One of the commands available in Privilege level 1 is the enable command, which you can use to enter a specific privilege level. • Privilege level 0 - contains only the end, enable, and disable commands. • Privilege level 15 - the default level for the enable command, is the highest level. In this level you can access any command in Dell Networking OS. Privilege levels 2 through 14 are not configured and you can customize them for different users and access. After you configure other privilege levels, enter those levels by adding the level parameter after the enable command or by configuring a user name or password that corresponds to the privilege level. For more information about configuring user names, refer to Configuring a Username and Password. By default, commands in Dell Networking OS are assigned to different privilege levels. You can access those commands only if you have access to that privilege level. For example, to reach the protocol spanning-tree command, log in to the router, enter the enable command for privilege level 15 (this privilege level is the default level for the command) and then enter CONFIGURATION mode. You can configure passwords to control access to the box and assign different privilege levels to users. Dell Networking OS supports the use of passwords when you log in to the system and when you enter the enable command. If you move between privilege levels, you are prompted for a password if you move to a higher privilege level.
