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 GigabitEthernet 0/0
