You can change the host name withthe hostname command.• CLI mode is the second part of the prompt and reflects the current CLI mode. For a list of the DellNetworking OS command modes, refer to the command mode list in the Accessing the CommandLine section.The CLI prompt changes as you move up and down the levels of the command structure. Starting withCONFIGURATION mode, the command prompt adds modifiers to further identify the mode. For moreinformation about command modes, refer to the Command Modes section.Using the Keyword no CommandTo disable, delete or return to default values, use the no form of the commands.For most commands, if you type the keyword no in front of the command, you disable that command ordelete it from the running configuration. In this guide, the no form of the command is described in theSyntax portion of the command description.Filtering show CommandsTo find specific information, display certain information only or begin the command output at the firstinstance of a regular expression or phrase, you can filter the display output of a show command.When you execute a show command, and then enter a pipe ( | ), one of the following parameters, and aregular expression, the resulting output either excludes or includes those parameters.NOTE: Dell Networking OS accepts a space before or after the pipe, no space before or after thepipe, or any combination.
