Command Line Interface


This chapter describes how to use the SCE platform Command-Line Interface (CLI), its hierarchical structure, authorization levels and its help features. The Command-Line Interface is one of the SCE platform management interfaces.

The CLI is accessed through a Telnet session or directly via the console port on the front panel of the SCE platform. When you enter a Telnet session, you enter as the simplest level of user, in the User Exec mode.

The SCE platform supports up to six concurrent CLI sessions; five sessions initiated by Telnet connection, and one session on the console port.

Information About Authorization and Command Levels (Hierarchy)

When using the CLI there are two important concepts that you must understand to navigate:

Authorization Level — Indicates the level of commands you can execute. A user with a simple authorization level can only view some information in the system, while a higher level administrator can actually make changes to configuration.

This manual documents commands at all authorization levels.  

Command Hierarchy Level — Provides you with a context for initiating commands. Commands are broken down into categories and you can only execute each command within the context of its category. For example, to configure parameters related to the Line Card, you need to be within the LineCard Interface Configuration Mode. CLI Command Hierarchy 

The following sections describe the available Authorization and Command Hierarchy Levels and how to maneuver within them.

The on-screen prompt indicates both your authorization level and your command hierarchy level, as well as the assigned host name.  


Note Throughout the manual, SCE is used as the sample host name.


CLI Command Hierarchy

The set of all CLI commands is grouped in hierarchical order, according to the type of the commands. The first two levels in the hierarchy are the User Exec and Privileged Exec modes. These are non-configuration modes in which the set of available commands enables the monitoring of the SCE platform, file system operations, and other operations that cannot alter the configuration of the SCE platform.

The next levels in the hierarchy are the Global and Interface configuration modes, which hold a set of commands that control the global configuration of the SCE platform and its interfaces. Any of the parameters set by the commands in these modes should be saved in the startup configuration, such that in the case of a reboot, the SCE platform restores the saved configuration.

The following table shows the available CLI modes.

Table 2-2 CLI Modes

Mode

Description

Level

Prompt indication

User Exec

Initial mode. Also allows monitoring of the system (show commands).

User/Viewer

SCE >

Privileged Exec

General administration; file system manipulations and control of basic parameters that do not change the configuration of the SCE platform.

Admin/ Root

SCE #

Global Configuration

Configuration of general system parameters, such as DNS, host name, and time zone.

Admin/ Root

SCE (config)#

Management Interface Configuration

Configuration of management interface parameters, such as the Ethernet interface properties and selection of the active port.

Admin/ Root

SCE(config if)#

Interface Configuration

Configuration of specific system interface parameters, such as the Line Card, and the Ethernet interfaces.

Admin/ Root

SCE (config if)#

Line Configuration

Configuration of Telnet lines, such as an access-list.

Admin/ Root

SCE (config-line)#


When you login to the system, you have the User authorization level and enter User Exec mode. Changing the authorization level to Viewer does not change the mode. Changing the authorization level to Admin automatically moves you to Privileged Exec mode. To move to any of the configuration modes, you must enter commands specific to that mode.

A telnet session begins with a request for password, and will not continue until the proper user password is supplied. This enhances the security of the system by not revealing its identity to unauthorized people.

The list of available commands in each mode can be viewed using the question mark `?' at the end of the prompt.

The figure below, illustrates the hierarchical structure of the CLI modes, and the CLI commands used to enter and exit a mode.

Figure 2-1 CLI Command Modes

The following commands are used to enter the different configure interface modes and the Line Configuration Mode:

E1 interfaceLineCard 0

E2 interfaceMng 0/1or 0/2 (management port, all platforms)

E3 interfaceGigabitEthernet 0/1or 0/2 (line ports, SCE 1000 platform)

E3 interfaceGigabitEthernet 0/1, 0/2, 0/3, or 0/4 (line ports, SCE 2000 4xGBE platform)

E3 interfaceFastEthernet 0/1, 0/2, 0/3, or 0/4 (line ports, SCE 2000 4/8xFE platform)

E4 line vty 0


Note Although the system supports up to five concurrent Telnet connections, you cannot configure them separately. This means that any number you enter in the line vtycommand ( 0, 1, 2, 3or 4) will act as a 0and configure all five connections together.



Note In order for the auto-completion feature to work, when you move from one interface configuration mode to another, you must first exit the current interface configuration mode (as illustrated in the above figure).


Example:

This example illustrates moving into and out of configuration modes as follows:

Enter global configuration mode

Configure the SCE platform time zone

Enter Mng Interface configuration mode for Mng port 1

Configure the speed of the management interface

Exit the Mng Interface configuration mode to the global configuration mode

Enter the LineCard Interface configuration

Define the link mode

Exit LineCard Interface configuration mode to the global configuration mode

Exit global configuration mode

SCE#configure 
SCE(config)#clock timezone PST -10 
SCE(config)#interface Mng 0/1 
SCE(config if)#speed 100 
SCE(config if)#exit 
SCE(config)#interface LineCard 0 
SCE(config if)#link-mode all-links forwarding 
SCE(config if)#exit

Information About CLI Help Features

CLI provides context sensitive help. Two types of context sensitive help are supported:

Partial Help 

Argument Help 

The [no] Prefix 

Partial Help

To obtain a list of commands that begin with a particular character string, enter the abbreviated command entry immediately followed by a question mark (?). This form of help is called partial help, because it lists only the keywords or arguments that begin with the abbreviation you entered.

Example:

The following example illustrates how typing c?displays all available arguments that start with the letter c.

SCE(config)#snmp-server c? 
Community		contact 
SCE(config)#snmp-server c

Argument Help

To obtain a list of command's associated keywords or parameters, type a question mark (?) in place of a keyword or parameter on the command line.


Note If <Enter> is acceptable input, the symbol <cr> represents the Enter key.


Example:

The following example illustrates how to get a list of all arguments or keywords expected after the command snmp-server.

SCE(config)#snmp-server ? 
Community	Define community string 
Contact		Set system contact 
Enable		Enable the SNMP agent 
Host   	 	Set traps destination 
Location		Set system location 
SCE(config)# snmp-server 

When asking for help on particular parameter, the system informs you of the type of data that is an accepted legal value. The types of parameters supported are:

STRING

When a String is expected, you can enter any set of characters or digits. If the string has a space as one of its characters, use double-quote (") marks to enclose the string.

DECIMAL

Any decimal number. Positive number is assumed, for negative numbers use the "-" symbol.

HEX

A hexadecimal number; must start with either 0x or 0X.


Example:

The following example illustrates the use of ?to get help on commands syntax. In this example, you can enter either the word running-config, or any name of a file, after the word copy.

SCE#copy ? 
	running-config		Copy running configuration file 
	STRING			Source file name 
SCE#copy

The [no] Prefix

Many CLI commands offer the option of adding the word nobefore the command to disable the feature controlled by the command or revert it to its default configuration. This notation is shown in the CLI Command Reference (on page 1 ) as [no]to denote it is optional.

For example, no service telnetddisables the telnet server. Enabling the telnet server is done by typing service telnetd.

Information About Navigational and Shortcut Features

Command History 

Keyboard Shortcuts 

Tab Completion 

FTP User Name and Password 

Command History

CLI maintains a history buffer of the most recent commands you used in the current CLI session for quick retrieval. Using the keyboard, you can navigate through your last commands, one by one, or all commands that start with a given prefix. By default, the system saves the last 30 commands you typed. You can change the number of commands remembered using the history sizecommand.

To use the history functions, use the keys shown in the following table.

Table 2-3 Keyboard Shortcuts for History Functions

Arrow

CTRL-Y

Completes the word when there is only one possible completion.

<Tab>

Completes the word when there is only one possible completion. (Same functionality as <Tab>.)

CTRL-I


Tab Completion

The CLI interface features tab completion. When you type in the first letters of a command and type <Tab>, the system automatically fills in the rest of the command or keyword. This feature works only when there is one command that could be possible using the starting letters.

Example:

The letters snm followed by <Tab> will be completed to the command snmp-server.

SCE(config)#snm<Tab> 
SCE(config)#snmp-server

If you type <Enter> instead of <Tab>, and there is no ambiguity, the system actually carries out the command which would be filled in by the rest of the word.

Example:

The following example displays how the system completes a partial (unique) command for the enable command. Because enable does not require any parameters, the system simply carries out the enable command when the user presses Enter.

SCE>en<Enter> 
Password:    
SCE#

FTP User Name and Password

CLI enables saving ftp user name and password to be used in FTP operations—download and upload, per session.

These settings are effective during the current CLI session.

The following example illustrates how to set FTP password and user name and the use in these settings for getting a file named config.tmp from a remote station using FTP protocol.

SCE#ip ftp password vk
SCE#ip ftp username vk
SCE#copy ftp://@10.1.1.253/h:/config.tmp myconf.txt
connecting 10.1.1.253 (user name vk password vk) to retrieve config.tmp  
SCE#

Information About Managing Command Output

Some commands, such as many show commands, may have many lines of output. There are several ways of managing the command output:

Scrolling options — When the command output is too large to be displayed all at once, you can control whether the display scrolls line by line or refreshes the entire screen.

Filtering options — You can filter the output so that output lines are displayed only if they include or exclude a specified expression.

Redirecting to a file — You can send the output to a specified file.

Note that by default, the show commands act the same as the more commands; that is, the output is displayed interactively a single screen at a time. Use the no more (on page ) command to disable this feature so that show commands display the complete output all at one time.

Scrolling the Screen Display 

Filtering Command Output 

Redirecting Command Output to a File 

Scrolling the Screen Display

The output of some showand dircommands is quite lengthy and cannot all be displayed on the screen at one time. Commands with many lines of output are displayed in chunks of 24 lines. You can choose to scroll the display line by line or refresh the entire screen. At the prompt after any line, you can type one of the following keys for the desired action:

<Enter>

Show one more line

<Space>

Show 24 more lines (a new chunk)

<g>

Stop prompting for more

<?>

Display a help string showing possible options

Any other key- Quit showing the file

Filtering Command Output

You can filter the output of certain commands, such as show, more, and dir, so that output lines are displayed only if they include or exclude a specified expression. The filtering options are as follows:

include — Shows all lines that include the specified text.

exclude — Does not show any lines that include the specified text.

begin — Finds the first line that includes the specified text, and shows all lines starting from that line. All previous lines are excluded.

The syntax of filtered commands is as follows:

<command>| include <expression>

<command>| exclude <expression>

<command>| begin <expression>

Following is an example of how to filter the show versioncommand to display only the last part of the output, beginning with the version information.

SCE# show version begin revision

Redirecting Command Output to a File

You can redirect the output of commands, such as show, more, and dir, to a file. When writing the output of these commands to a file, you can specify either of the following options:

redirect — The new output of the command will overwrite the existing contents of the file.

append — The new output of the command will be appended to the existing contents of the file.

The syntax of redirection commands is as follows:

<command>| redirect <file-name>

<command>| append <file-name>

Following is an example of how to do the following:

Filter the more command to display from a csv subscriber file only the gold package subscribers.

Redirect that output to a file named current_gold_subscribers. The output should not overwrite existing entries in the file, but should be appended to the end of the file.

SCE# more subscribers_10.10.2004 include gold append current_gold_subscribers

CLI Authorization Levels

The SCE platform has four authorization levels, which represent the user access permissions. When you initially connect to the SCE platform, you automatically have the most basic authorization level, that is User, which allows minimum functionality.

To monitor the system, you must have Viewer authorization, while to perform administrative functions on the SCE platform, you must have Admin or Root authorization. A higher level of authorization is accessed by logging in with appropriate password, as described in the procedures below.

In each authorization level, all the commands of the lower authorization layers are available in addition to commands that are authorized only to the current level.

The following CLI commands are related to authorization levels:

enable

disable

Each authorization level has a value (number) corresponding to it. When using the CLI commands, use the values, not the name of the level, as shown in the following table.

Table 2-5 Authorization Levels

Level

Description

Value

Prompt

User

Password required. This level enables basic operational functionality.

DETAILED STEPS


Step 1 From the SCE>prompt, type enable 5 and press Enter..

The system prompts for a password by showing the prompt Password:

Step 2 Type in the password for the Viewer level and press Enter


Note Note that the password is an access-level authorization setting, not an individual user password. The system prompt SCE>does not change when you move from User to Viewer level.



How to log in with Root level authorization


Step 1 Initiate a telnet connection.

Step 2 A Password: prompt appears. Type in the user level password and press Enter.

The SCE>prompt appears.

You now have user level authorization.

Step 3 From the SCE>prompt, type enable 15and press Enter.

The system prompts for a password by showing the prompt Password:

Step 4 Type in the password for the Root level and press Enter.

.Note that the password is an access-level authorization setting, not an individual user password.

The system prompt changes to SCE#>to show you are now in Root level.


This example illustrates how to change the authorization level from User to Root, and then revert back to Admin. No password is required for moving to a lower authorization level.

Management interface configuration mode

Interface configuration mode

Line configuration mode

When you are in one of these configuration modes, it is possible to execute an EXEC mode command (such as a showcommand) or a privileged EXEC (such as show running-config) without exiting to the relevant command mode. Use the 'do' command for this purpose.

How to execute an exec mode command from a configuration command mode


Step 1 At the SCE(config)# (or SCE(config if)# ) prompt, type do <command>.

The specified command executes without exiting to the appropriate exec command mode.


The following example shows how to display the running configuration while in interface configuration mode.

SCE(config if#) do show running-config

How to create a CLI script

The CLI scripts feature allows you to record several CLI commands together as a script and play it back. This is useful for saving repeatable sequence of commands , such as software upgrade. For example, if you are configuring a group of SCE platforms and you want to run the same configuration commands on each platform, you could create a script on one platform and run it on all the other SCE platforms. The available script commands are:

script capture

script stop

script print

script run


Step 1 At the SCE# prompt, type script capture sample1.scrwhere sample1.scris the name of the script.

Step 2 Perform the actions you want to be included in the script.

Step 3 Type script stop.

The system saves the script.


The following is an example of recording a script for upgrading software.

SCE#script capture upgrade.scr 
SCE#configureSCE(config)#boot system new.pkg
Verifying package file... 
Package file verified OK. 
SCE(config)#exit
SCE#copy running-config startup-config
