Navigating the CLI
Dell Networking OS displays a CLI prompt comprised of the host name and CLI mode.
• Host name is the initial part of the prompt and is “Dell” by default. You can change the host name with
the hostname command.
• CLI mode is the second part of the prompt and reflects the current CLI mode. For a list of the Dell
Networking OS command modes, refer to the command mode list in the Accessing the Command
Line section.
The CLI prompt changes as you move up and down the levels of the command structure. Starting with
CONFIGURATION mode, the command prompt adds modifiers to further identify the mode. For more
information about command modes, refer to the Command Modes section.
Using the Keyword no Command
To 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 or
delete it from the running configuration. In this guide, the no form of the command is described in the
Syntax portion of the command description.
Filtering show Commands
To find specific information, display certain information only or begin the command output at the first
instance 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 a
regular 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 the
pipe, or any combination. For example: Dell#command | grep gigabit |except regular-
expression | find regular-expression
display displays additional configuration information
except displays only the text that does not match the pattern (or regular expression)
find searches for the first occurrence of a pattern
grep displays text that matches a pattern.
The grep command option has an ignore-case suboption that makes the search
case-insensitive. For example, the commands:
show run |
grep
Ethernet
returns a search result with instances containing a capitalized
“Ethernet,” such as interface TenGigabitEthernet
1/1
