2CLI Basics

This chapter describes the command structure and command modes. FTOS commands are in a text-based interface that allows you to launch commands, change the command modes, and configure interfaces and protocols.

This chapter covers the following topics:

• Accessing the Command Line• Multiple Configuration Users• Navigating the Command Line Interface• Obtaining Help• Using the Keyword No• Filtering show Commands• Command Modes

Accessing the Command LineWhen the system boots successfully, you are positioned on the command line in the EXEC mode and not prompted to log in. You can access the commands through a serial console port or a Telnet session. When you Telnet into the switch, you are prompted to enter a login name and password.

Figure 2-1 is an example of a successful Telnet login session.

Figure 2-1. Login Example

Once you log into the switch, the prompt provides you with current command-level information (refer to Table 2-1).

telnet 172.31.1.53Trying 172.31.1.53...Connected to 172.31.1.53.Escape character is '^]'.Login: usernamePassword: FTOS>

om Multiple Configuration Users

When a user enters the CONFIGURATION mode and another user(s) is already in that configuration mode, FTOS generates an alert warning message similar to the following:

Figure 2-2. Configuration Mode User Alert

When another user enters the CONFIGURATION mode, FTOS sends a message similar to the following, where the user in this case is “admin” on vty2:

% Warning: User "admin" on line vty2 "172.16.1.210" is in configuration

Navigating the Command Line InterfaceThe Command Line Interface (CLI) prompt displayed by FTOS is comprised of:

• “hostname”— the initial part of the prompt, “FTOS” by default. You can change it with the hostname command, as described in hostname.

• The second part of the prompt, reflecting the current CLI mode, as shown in Table 2-1.

The CLI prompt changes as you move up and down the levels of the command structure. Table 2-1 lists the prompts and their corresponding command levels, called modes. Starting with the CONFIGURATION mode, the command prompt adds modifiers to further identify the mode. The command modes are explained in Command Modes.

FTOS#conf

% Warning: The following users are currently configuring the system:

User "" on line console0 User "admin" on line vty0 ( 123.12.1.123 ) User "admin" on line vty1 ( 123.12.1.123 ) User "Irene" on line vty3 ( 123.12.1.321 )

Obtaining HelpAs soon as you are in a command mode there are several ways to access help.

• To obtain a list of keywords at any command mode, do the following: — Enter a ? at the prompt or after a keyword. There must always be a space before the ?.

• To obtain a list of keywords with a brief functional description, do the following:— Enter help at the prompt.

• To obtain a list of available options, do the following:

FTOS(conf-if)#FTOS(conf-if-gi-0/0)#FTOS(conf-if-te-0/0)#FTOS(conf-if-lo-0)#FTOS(conf-if-nu-0)#FTOS(conf-if-po-0)#FTOS(conf-if-vl-0)#FTOS(conf-if-so-0/0)#FTOS(conf-if-ma-0/0)#FTOS(conf-if-range)#

om — Type a keyword followed by a space and a ?

• Type a partial keyword followed by a ? — A display of keywords beginning with the partial keyword is listed.

Figure 2-3 illustrates the results of entering ip ? at the prompt.

Figure 2-3. Partial Keyword Example

When entering commands, you can take advantage of the following timesaving features:

• The commands are not case sensitive.• You can enter partial (truncated) command keywords. For example, you can enter int gig int

interface for the interface gigabitethernet interface command.• Use the TAB key to complete keywords in commands. • Use the up arrow key to display the last enabled command.• Use either the Backspace key or the Delete key to erase the previous character.

Use the left and right arrow keys to navigate left or right in the FTOS command line. Table 2-2 defines the key combinations valid at the FTOS command line.

Using the Keyword NoTo 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 will disable that command or delete it from the running configuration. In this document, the no form of the command is discussed in the Command Syntax portion of the command description.

Filtering show CommandsYou can filter the display output of a show command to find specific information, to display certain information only, or to begin the command output at the first instance of a regular expression or phrase.

When you execute a show command, followed by a pipe ( | ) and one of the parameters listed below and a regular expression, the resulting output either excludes or includes those parameters, as defined by the parameter:

• display — display additional configuration information

Table 2-2. Short-cut Keys and their Actions

Key Combination Action

CNTL-A Moves the cursor to the beginning of the command line.

CNTL-B Moves the cursor back one character.

CNTL-D Deletes character at cursor.

CNTL-E Moves the cursor to the end of the line.

CNTL-F Moves the cursor forward one character.

CNTL-I Completes a keyword.

CNTL-K Deletes all characters from the cursor to the end of the command line.

CNTL-L Re-enters the previous command.

CNTL-N Return to more recent commands in the history buffer after recalling commands with Ctrl-P or the up arrow key

CNTL-P Recalls commands, beginning with the last command

CNTL-R Re-enters the previous command.

CNTL-U Deletes the line.

CNTL-W Deletes the previous word.

CNTL-X Deletes the line.

CNTL-Z Ends continuous scrolling of command outputs.

Esc B Moves the cursor back one word.

Esc F Moves the cursor forward one word.

Esc D Deletes all characters from the cursor to the end of the word.

om • except— display only text that does not match the pattern (or regular expression)

• find — search for the first occurrence of a pattern • grep — display text that matches a pattern• no-more — do not paginate the display output • save - copy output to a file for future use

The grep command option has an ignore-case sub-option that makes the search case-insensitive. For example, the commands:

• show run | grep Ethernet would return a search result with instances containing a capitalized “Ethernet,” such as interface GigabitEthernet 0/0.

• show run | grep ethernet would not return the search result, above, because it only searches for instances containing a non-capitalized “ethernet.”

Executing the command show run | grep Ethernet ignore-case would return instances containing both “Ethernet” and “ethernet.”

Displaying All OutputTo display the output all at once (not one screen at a time), use the no-more 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 TimesYou can filter a single command output multiple times. 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 ModesTo navigate to various CLI modes, you need to use specific commands to launch each mode. Navigation to these modes is discussed in the following sections.

Command Modes CONFIGURATION

CommandHistory

UsageInformation

To display these changes in the show bootvar command output, you must save the running configuration to the startup configuration (copy running-config startup-config or write).

Dell Networking strongly recommends using local files for configuration (RPM0 or RPM1 flash or slot0).

remote-first Enter the keywords remote-first to attempt to load the boot configuration files from a remote location.

rpm0 Enter the keywords rpm0 first to specify the local boot configuration file for RPM 0.rpm1 Enter the keywords rpm1 first to specify the local boot configuration file for RPM 1.file-url Enter the location information:

• For a file on the internal Flash, enter flash:// followed by the filename.• For a file on the external Flash, enter slot0:// followed by the filename.

Version 7.5.1.0 Introduced on C-Series

E-Series original Command


When you specify a file as the boot config file, it is listed in the boot variables (bootvar) as LOCAL CONFIG FILE. If you do not specify a boot config file, then the startup-configuration is used, although the bootvar shows LOCAL CONFIG FILE = variable does not exist. When you specify a boot config file, the switch reloads with that config file, rather than the startup-config. Note that if you specify a local config file which is not present in the specified location, then the startup-configuration is loaded.

The write memory command always saves the running-configuration to the file labeled startup-configuration. When using a LOCAL CONFIG FILE other than the startup-config, use the copy command to save any running-configuration changes to that local file.

om Parameters


CommandHistory

UsageInformation

FTOS supports a maximum of 100 files, at the root directory level, on both the internal and external Flash.

The usbflash and rpm0usbflash commands are supported on E-Series ExaScale platform only. Refer to the FTOS Release Notes for a list of approved USB vendors.

When copying a file to a remote location (for example, using Secure Copy (SCP)), enter only the keywords and FTOS prompts you for the rest of the information.

For example, when using SCP, you can enter copy running-config scp: The running-config is the source, and the target is specified in the ensuing prompts. FTOS prompts you to enter any required information, as needed for the named destination—remote destination, destination filename, user ID and password, etc.

When you use the copy running-config startup-config command to copy the running configuration (the startup configuration file amended by any configuration changes made since the system was started) to the startup configuration file, FTOS creates a backup file on the internal flash of the startup configuration.

FTOS supports copying the running-configuration to a TFTP server or to an FTP server:

file-url Enter the following location keywords and information:• To copy a file from the internal FLASH, enter flash:// followed by the filename.• To copy a file on an FTP server, enter ftp://user:password@hostip/filepath• To copy a file from the internal FLASH on RPM0, enter rpm0flash://filepath• To copy a file from the external FLASH on RPM0, enter rpm0slot0://filepath• To copy a file from the internal FLASH on RPM1, enter rpm1flash://filepath• To copy a file from the external FLASH on RPM1, enter rpm1slot0://filepath• To copy the running configuration, enter the keyword running-config.• To copy the startup configuration, enter the keyword startup-config.• To copy using Secure Copy (SCP), enter the keyword scp: (If scp: is entered in the

source position, then enter the target URL; If scp: is entered in the target position, first enter the source URL; see below for examples.)

cp Enable coredump for the CP.linecard Enable coredump for a linecard.rps Enable coredump for RP 1 and 2.

stack-unit Enable coredump for the stack-unit.Range: S55 0-11All other S-Series 0-7


CommandHistory

UsageInformation

The Kernel core dump can be large and may take up to 5 to 30 minutes to upload. FTOS does not overwrite application coredumps so you should delete them as necessary to conserve space on the flash; if the flash is out of memory, the coredump is aborted. On the S-Series, if the FTP server is not reachable, the application coredump is aborted. FTOS completes the coredump process and waits until the upload is complete before rebooting the system.

Parameters

Defaults Crash kernel files are uploaded to flash by default.


CommandHistory

UsageInformation

Since flash space may be limited, using this command ensures your entire crash kernel files are uploaded successfully and completely.

Syntax restore factory-defaults stack-unit {0-11 | all} {clear-all | nvram}

Parameters




FTOS#pwd flash: FTOS#

cd Change directory.

url Enter the following keywords and a filename:• For a file on the internal Flash, enter flash:// followed by the filename.• For a file on the external Flash, enter slot0:// followed by the filename.





factory-defaults Return the system to its factory default mode.

0-11 Enter this keyword to restore only the mentioned stack-unit.

all Enter this keyword to restore all units in the stack.



CommandHistory

UsageInformation

Restoring factory defaults deletes the existing startup configuration and all persistent settings (stacking, fanout, etc.).

Dell Networking recommends backing up the startup configuration before using this command.

When restoring all units in a stack, all the units in the stack are placed into stand-alone mode.

When restoring a single unit in a stack, that unit is placed in stand-alone mode. No other units in the stack are affected.

When restoring units in stand-alone mode, the units remain in stand-alone mode after the restoration.

After the restore is complete, the units power cycle immediately.

clear-all Enter this keyword to reset the NvRAM and the system startup configuration.

nvram Enter this keyword to reset the NvRAM only.
