www.dell.com | support.dell.com Displaying All Output To display the output all at once (not one screen at a time), use the no-more command after the pipe. This is similar to the terminal length screen-length command except that the no-more option affects the output of just the specified command. For example: FTOS#show running-config | no-more Filtering Command Output Multiple Times You can filter a single command output multiple times. To do this, place the save option as the last filter. For example: FTOS# command | grep regular-expression | except regular-expression | grep other-regular-expression | find regular-expression | no-more | save Command Modes To navigate to various CLI modes, use specific commands to launch each mode. Navigation to these modes is described in the following sections. EXEC Mode When you initially log in to the switch, by default you are logged into EXEC mode. This mode allows you to view settings and to enter EXEC Privilege mode to configure the device. While you are in EXEC mode, the > prompt is displayed following the "hostname" prompt (which is "FTOS" by default). You can change this using the hostname command. For more information, refer to the hostname command. Each mode prompt is preceded by the hostname. EXEC Privilege Mode The enable command accesses EXEC Privilege mode. If an administrator has configured an Enable password, you are prompted to enter the password here. EXEC Privilege mode allows you to access all commands accessible in EXEC mode, plus other commands, such as to clear ARP entries and IP addresses. In addition, you can access CONFIGURATION mode to configure interfaces, routes, and protocols on the switch. While you are logged in to EXEC Privilege mode, the # prompt displays. CONFIGURATION Mode In EXEC Privilege mode, use the configure command to enter CONFIGURATION mode and configure routing protocols and access interfaces. To enter CONFIGURATION mode: 1. Verify that you are logged in to EXEC Privilege mode. 2. Enter the configure command. The prompt changes to include (conf). 18 | CLI Basics

CLI Basics

www.dell.com | support.dell.com

Displaying All Output

To display the output all at once (not one screen at a time), use the

no-more

command after the pipe.

This is similar to the

terminal

length

screen-length

command except that the

no-more

option affects

the output of just the specified command. For example:

FTOS#

show running-config | no-more

Filtering Command Output Multiple Times

You can filter a single command output multiple times. To do this, place the

save

option as the last

filter. For example:

FTOS#

command

grep

regular-expression

except

regular-expression

grep

other-regular-expression

find

regular-expression

no-more | save

Command Modes

To navigate to various CLI modes, use specific commands to launch each mode. Navigation to these

modes is described in the following sections.

EXEC Mode

When you initially log in to the switch, by default you are logged into EXEC mode. This mode allows

you to view settings and to enter EXEC Privilege mode to configure the device. While you are in

EXEC mode, the

prompt is displayed following the “hostname” prompt (which is “FTOS” by

default). You can change this using the

hostname

command. For more information, refer to the

hostname

command. Each mode prompt is preceded by the hostname.

EXEC Privilege Mode

The

enable

command accesses EXEC Privilege mode. If an administrator has configured an

Enable

password, you are prompted to enter the password here.

EXEC Privilege mode allows you to access all commands accessible in EXEC mode, plus other

commands, such as to clear ARP entries and IP addresses. In addition, you can access

CONFIGURATION mode to configure interfaces, routes, and protocols on the switch. While you are

logged in to EXEC Privilege mode, the

prompt displays.

CONFIGURATION Mode

In EXEC Privilege mode, use the

configure

command to enter CONFIGURATION mode and

configure routing protocols and access interfaces.

To enter CONFIGURATION mode:

Verify that you are logged in to EXEC Privilege mode.

Enter the

configure

command. The prompt changes to include (conf).
