However, at times, you might need to allowothers access to the router and you can limit that access to a subset of commands. In Dell Networking OS, you can configure aprivilege level for users who need limited access to the system.Every command in Dell Networking OS is assigned a privilege level of 0, 1, or 15. You can configure up to 16 privilege levels in DellNetworking OS. Dell Networking OS is pre-configured with three privilege levels and you can configure 13 more. The three pre-configured levels are:• Privilege level 1 — is the default level for EXEC mode. At this level, you can interact with the router, for example, view someshow 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 specificprivilege 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 commandin 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 byconfiguring 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 youhave access to that privilege level. For example, to reach the protocol spanning-tree command, log in to the router, enterthe enable command for privilege level 15 (this privilege level is the default level for the command) and then enterCONFIGURATION mode.You can configure passwords to control access to the box and assign different privilege levels to users. Dell Networking OS supportsthe use of passwords when you log in to the system and when you enter the enable command. If you move between privilegelevels, you are prompted for a password if you move to a higher privilege level.Security 633
