2CLI Basics

This chapter describes the command structure and command modes. FTOS commands are in a text-based interface that allows you to use 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.

om Multiple Configuration Users

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

Figure 2-2. Configuration Mode User Alert

When another user enters the CONFIGURATION mode, FTOS adds 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.

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

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.

Note: FTOS accepts a space before or after the pipe, no space before or after the pipe, or any combination. For example:FTOS#command | grep gigabit |except regular-expression | find regular-expression

Note: Some of the following modes are not available on C-Series or S-Series.

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

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.

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:

om copy running-config ftp:

Command Example: copy running-config scp:

In this example — copy scp: flash: — specifying SCP in the first position indicates that the target is to be specified in the ensuing prompts. Entering flash: in the second position means that the target is the internal Flash. In this example the source is on a secure server running SSH, so the user is prompted for the UDP port of the SSH server on the remote host.

Version 8.4.1.0 Added IPv6 addressing support for FTP, TFTP, and SCP.


Version 6.1.1.0 Introduced


UsageInformation

In this streamline copy command, the source image is copied to the primary RPM and then, if specified, to the standby RPM. After the copy is complete, the new image file path on each RPM is automatically configured as the primary image path for the next boot. The current system image (the one from which the RPM booted) is automatically configured as the secondary image path.

FTOS supports IPv4 and IPv6 addressing for FTP, TFTP, and SCP.

copy running-config startup-config c e Copy running configuration to the startup configuration.

Syntax copy running-config startup-config {duplicate}


CommandHistory

UsageInformation

This command is useful for quickly making a changed configuration on one chassis available on external flash in order to move it to another chassis.

When you use the copy running-config startup-config duplicate command to copy the running configuration to the startup configuration, FTOS creates a backup file on the internal flash of the startup configuration.

deletec e s Delete a file from the flash. Once deleted, files cannot be restored.

Syntax delete flash-url [no-confirm]

Parameters


CommandHistory

Note: The keywords boot-image, synchronize-rpm, and external can be used on the Primary RPM only.



flash-url Enter the following location and keywords:• For a file or directory on the internal Flash, enter flash:// followed by the filename or

directory name.• For a file or directory on the external Flash, enter slot0:// followed by the filename or

directory name.

no-confirm (OPTIONAL) Enter the keyword no-confirm to specify that FTOS does not require user input for each file prior to deletion.

CommandHistory

UsageInformation

When you format flash:

1 The startup-config is erased.2 All cacheboot data files are erased and you must reconfigure cacheboot to regain it.3 All generated SSH keys are erased and you must recreate them.4 All archived configuration files are erased.5 All trace logs, crash logs, core dumps, and call-home logs are erased.6 In-service Process patches are erased.

After reformatting is complete, three empty directories are automatically created on flash: CRASH_LOG_DIR, TRACE_LOG_DIR and NVTRACE_LOG_DIR.

Note: Version option is available on LC-ED-RPM only. LC-EE3-RPM, LC-EF-RPM, and LC-EF3-RPM supports DOS 2.0 only.

logging coredumpc e Enable coredump.

Syntax logging coredump {cp | linecard {number | all} | rps}

Parameters

Defaults The kernal coredump is enabled by default for RP 1 and 2 on E-Series. The kernel coredump for CP and application coredump are disabled on all systems by default.


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 core dumps 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 wait until the upload is complete before rebooting the system.

RelatedCommands

logging coredump serverc e s Designate a server to upload core dumps.
