cisco ios software command line interface

The chapter describes basic Cisco IOS software command-line interfaces that you may need to know before you load/upgrade the MWAM application image (see. The Cisco IOS command-line interface (CLI) is the primary user interface used The list of commands will vary depending on the software feature set and. This chapter provides information for understanding and using the Network Analysis Module (NAM) software by using the command-line interface (CLI). SPLASHTOP BROWSER PAGE LOAD ERROR

Return key. When the cursor first reaches the end of the line, the line is shifted ten spaces to the left and redisplayed. Each time the cursor reaches the end of the line, the line is again shifted ten spaces to the left. The software assumes that you have a terminal screen that is 80 columns wide. If you have a different width, use the terminal width privileged EXEC command to set the width of your terminal.

Use line wrapping with the command history feature to recall and modify previous complex command entries. You can search and filter the output for show and more commands. This is useful when you need to sort through large amounts of output or if you want to exclude output that you do not need to see.

Using these commands is optional. Expressions are case sensitive. For example, if you enter exclude output , the lines that contain output are not displayed, but the lines that contain output appear. You manage the switch stack and the stack member interfaces through the active switch. You cannot manage stack members on an individual switch basis. You can connect to the active switch through the console port or the Ethernet management port of one or more stack members.

Be careful with using multiple CLI sessions on the active switch. Commands that you enter in one session are not displayed in the other sessions. Therefore, it is possible to lose track of the session from which you entered commands. If you want to configure a specific stack member port, you must include the stack member number in the CLI command interface notation.

To debug the standby switch, use the session standby ios privileged EXEC command from the active switch to access the IOS console of the standby switch. To debug a specific stack member, use the session switch stack-member-number privileged EXEC command from the active switch to access the diagnostic shell of the stack member. For more information about these commands, see the switch command reference. Before you can access the CLI, you must connect a terminal or a PC to the switch console or connect a PC to the Ethernet management port and then power on the switch , as described in the hardware installation guide that shipped with your switch.

If your switch is already configured, you can access the CLI through a local console connection or through a remote Telnet session, but your switch must first be configured for this type of access. You can use one of these methods to establish a connection with the switch :. Connect the switch console port to a management station or dial-up modem, or connect the Ethernet management port to a PC.

For information about connecting to the console or Ethernet management port, see the switch hardware installation guide. The switch must have network connectivity with the Telnet or SSH client, and the switch must have an enable secret password configured. After you connect through the console port, through the Ethernet management port, through a Telnet session or through an SSH session, the user EXEC prompt appears on the management station.

Use this mode to Change terminal settings. Perform basic tests. Display system information. Switch Enter disable to exit. Use this mode to configure parameters that apply to the entire switch. VLAN configuration While in global configuration mode, enter the vlan vlan-id command. Switch config-vlan To exit to global configuration mode, enter the exit command.

Interface configuration While in global configuration mode, enter the interface command with a specific interface. Switch config-if To exit to global configuration mode, enter exit. Use this mode to configure parameters for the Ethernet ports. Line configuration While in global configuration mode, specify a line with the line vty or line console command. Switch config-line To exit to global configuration mode, enter exit. Use this mode to configure parameters for the terminal line.

Using the Help System You can enter a question mark? Understanding Abbreviated Commands You need to enter only enough characters for the switch to recognize the command as unique. This example shows how to enter the show configuration privileged EXEC command in an abbreviated form: Switch show conf. No and Default Forms of Commands Almost every configuration command also has a no form.

The possible keywords that you can enter with the command appear. You did not enter all of the keywords or values required by this command. You entered the command incorrectly. Configuration Logging You can log and view changes to the switch configuration. Configuring the Command History The software provides a history or record of commands that you have entered.

Changing the Command History Buffer Size By default, the switch records ten command lines in its history buffer. Recalling Commands To recall commands from the history buffer, perform one of the actions listed in this table. Disabling the Command History Feature The command history feature is automatically enabled. Enabling and Disabling Editing Features Although enhanced editing mode is automatically enabled, you can disable it and reenable it.

Editing Commands Through Keystrokes The keystrokes help you to edit the command lines. These keystrokes are optional. Ctrl-F or use the right arrow key Moves the cursor forward one character. Ctrl-A Moves the cursor to the beginning of the command line. Ctrl-E Moves the cursor to the end of the command line. Esc B Moves the cursor back one word. Esc F Moves the cursor forward one word. Ctrl-T Transposes the character to the left of the cursor with the character located at the cursor.

Delete or Backspace key Erases the character to the left of the cursor. Ctrl-D Deletes the character at the cursor. Ctrl-K Deletes all characters from the cursor to the end of the command line. Ctrl-U or Ctrl-X Deletes all characters from the cursor to the beginning of the command line.

Ctrl-W Deletes the word to the left of the cursor. Esc D Deletes from the cursor to the end of the word. Esc C Capitalizes at the cursor. Esc L Changes the word at the cursor to lowercase. Esc U Capitalizes letters from the cursor to the end of the word. Ctrl-V or Esc Q Designates a particular keystroke as an executable command, perhaps as a shortcut. Return key Scrolls down a line or screen on displays that are longer than the terminal screen can display.

Note The More prompt is used for any output that has more lines than can be displayed on the terminal screen, including show command output. Space bar Scrolls down one screen. Ctrl-L or Ctrl-R Redisplays the current command line if the switch suddenly sends a message to your screen. Editing Command Lines That Wrap You can use a wraparound feature for commands that extend beyond a single line on the screen.

Searching and Filtering Output of show and more Commands You can search and filter the output for show and more commands. Note We recommend using one CLI session when managing the switch stack. Accessing the CLI Through a Console Connection or Through Telnet Before you can access the CLI, you must connect a terminal or a PC to the switch console or connect a PC to the Ethernet management port and then power on the switch , as described in the hardware installation guide that shipped with your switch.

Begin a session using Telnet, SSH, or console. Enter disable to exit. Switch config. Switch config-vlan. Switch config-if. Switch config-line. Step 1. Obtains a brief description of the help system in any command mode. Step 2. Example: Switch di? Obtains a list of commands that begin with a particular character string. Step 3. Step 4. Lists all commands available for a particular command mode. Step 5.

Step 6. Example: Switch config cdp holdtime? Disables the feature during the current terminal session in privileged EXEC mode. If you cannot remember a complete command name, or if you want to reduce the amount of typing you have to perform, enter the first few letters of the command, then press the Tab key.

The command line parser will complete the command if the string entered is unique to the command mode. If your keyboard does not have a Tab key, press Ctrl - I instead. The CLI will recognize a command once you have entered enough characters to make the command unique. For example, if you enter conf in privileged EXEC mode, the CLI will be able to associate your entry with the configure command, because only the configure command begins with conf.

When you use the command completion feature the CLI displays the full command name. The command is not executed until you use the Return or Enter key. This way you can modify the command if the full command was not what you intended by the abbreviation. If you enter a set of characters that could indicate more than one command, the system beeps to indicate that the text string is not unique. If the CLI cannot complete the command, enter a question mark?

Do not leave a space between the last letter you enter and the question mark? For example, entering co? Note that the characters you enter before the question mark appear on the screen to allow you to complete the command entry. The CLI stores commands or keywords that you delete in a history buffer.

Only character strings that begin or end with a space are stored in the buffer; individual characters that you delete using Backspace or Ctrl-D are not stored. To recall these items and paste them in the command line, use the following key combinations:. Ctrl - Y. Recalls the most recent entry in the buffer press keys simultaneously. Esc , Y. Recalls the previous entry in the history buffer press keys sequentially. Note that the Esc, Y key sequence will not function unless you press the Ctrl-Y key combination first.

If you press Esc, Y more than ten times, you will cycle back to the most recent entry in the buffer. The CLI provides a wrap-around feature for commands that extend beyond a single line on the screen. When the cursor reaches the right margin, the command line shifts ten spaces to the left.

You cannot see the first ten characters of the line, but you can scroll back and check the syntax at the beginning of the command. To scroll back, press Ctrl-B or the Left Arrow key repeatedly until you scroll back to the beginning of the command entry, or press Ctrl-A to return directly to the beginning of the line. In the following example, the access-list command entry extends beyond one line.

When the cursor first reaches the end of the line, the line is shifted ten spaces to the left and redisplayed. Each time the cursor reaches the end of the line, the line is again shifted ten spaces to the left. When you have completed the entry, press Ctrl-A to check the complete syntax before pressing the Return key to execute the command. If you have a different screen-width, use the terminal width user EXEC command to set the width of your terminal.

Use line wrapping in conjunction with the command history feature to recall and modify previous complex command entries. See the Recalling Commands section in this chapter for information about recalling previous command entries. Use any of the following keys or key combinations to delete command entries if you make a mistake or change your mind:.

Delete or Backspace. Deletes the character to the left of the cursor. Ctrl - D. Ctrl - K. Deletes all characters from the cursor to the end of the command line. Ctrl - U or Ctrl - X. Deletes all characters from the cursor to the beginning of the command line. Ctrl - W. Deletes the word to the left of the cursor. Esc , D. Deletes from the cursor to the end of the word.

For cases where output continues beyond the bottom of the screen, such as with the output of many? To resume output, press the Return key to scroll down one line, or press the Spacebar to display the next full screen of output. If output is pausing on your screen, but you do not see the --More-- prompt, try entering a lower value for the screen length using the length line configuration command or the terminal length privileged EXEC mode command.

Command output will not be paused if the length value is set to zero. If you are entering a command and the system suddenly sends a message to your screen, you can easily recall your current command line entry. To redisplay the current command line refresh the screen , use either of the following key combinations:. Ctrl - L or Ctrl - R. If you have mistyped a command entry, you can transpose the mistyped characters. To transpose characters, use the following key combination:.

Ctrl - T. Transposes the character to the left of the cursor with the character located to the right of the cursor. You can capitalize or lowercase words or capitalize a set of letters with simple key sequences. To change the capitalization of commands, use any of the following key sequences:. Esc , C. Esc , L. Changes the word at the cursor to lowercase.

Esc , U. Capitalizes letters from the cursor to the end of the word. You can configure the system to recognize a particular keystroke key combination or sequence as command aliases. In other words, you can set a keystroke as a shortcut for executing a command. To enable the system to interpret a keystroke as a command, use the either of the following key combinations before entering the command sequence:.

Configures the system to accept the following keystroke as a user-configured command entry rather than as an editing command. The editing features described in the previous sections are automatically enabled on your system. However, there may be some unique situations that could warrant disabling these editing features. For example, you may have scripts that conflict with editing functionality. To globally disable editing features, use the following command in line configuration mode:.

To disable the editing features for the current terminal session, use the following command in user EXEC mode:. To reenable the editing features for the current terminal session, use the following command in user EXEC mode:. To reenable the editing features for a specific line, use the following command in line configuration mode:.

The Cisco IOS CLI provides ways of searching through large amounts of command output and filtering output to exclude information you do not need. These features are enabled for show and more commands, which generally display large amounts of data. Pressing Return displays the next line; pressing the Spacebar displays the next screen of output. In the following example, suppose you want to set the clock. Use context-sensitive help to determine the correct command syntax for setting the clock.

The help output shows that the set keyword is required. Determine the syntax for entering the time:. The system indicates that you need to provide additional arguments to complete the command. Press Ctrl-P or the Up Arrow to automatically repeat the previous command entry. Then add a space and question mark? To list the correct syntax, enter the command up to the point where the error occurred and then enter a question mark?

Enter the year using the correct syntax and press Enter or Return to execute the command:. The following is partial sample output from the more nvram:startup-config begin privileged EXEC mode command that begins unfiltered output with the first line that contains the regular expression ip.

At the --More-- prompt, the user specifies a filter to exclude output lines that contain the regular expression ip. The following is partial sample output of the more nvram:startup-config include privileged EXEC command. It only displays lines that contain the regular expression ip. The following is partial sample output from the more nvram:startup-config exclude privileged EXEC command.

It excludes lines that contain the regular expression service. At the --More-- prompt, the user specifies a filter with the regular expression Dialer1. Specifying this filter resumes the output with the first line that contains Dialer1. The use of the keywords begin Fast Ethernet after the pipe begins unfiltered output with the first line that contains the regular expression Fast Ethernet. At the --More-- prompt, the user specifies a filter that displays only the lines that contain the regular expression Serial.

The following is partial sample output from the show buffers exclude command. It excludes lines that contain the regular expression 0 misses. At the --More-- prompt, the user specifies a search that continues the filtered output beginning with the first line that contains Serial0. The use of the include is keywords after the pipe causes the command to display only lines that contain the regular expression is. The parenthesis force the inclusion of the spaces before and after is. At the --More-- prompt, the user specifies a search that continues the filtered output beginning with the first line that contains Serial Skip to content Skip to search Skip to footer.

From global configuration mode you can enter a variety of protocol-specific or feature-specific configuration modes. The CLI hierarchy requires that you enter these specific configuration modes only through global configuration mode. As an example, this chapter describes interface configuration mode , a commonly used configuration mode. From configuration modes, you can enter configuration submodes. Configuration submodes are used for the configuration of specific features within the scope of a given configuration mode.

As an example, this chapter describes the subinterface configuration mode , a submode of the interface configuration mode. ROM monitor mode is a separate mode used when the router cannot boot properly. If your system router, switch, or access server does not find a valid system image to load when it is booting, the system will enter ROM monitor mode.

You also can get a list of the arguments and keywords available for any command with the context-sensitive help feature. To get help specific to a command mode, a command name, a keyword, or an argument, use any of the following commands:. Note that the system prompt will vary depending on which configuration mode you are in.

When context-sensitive help is used, the space or lack of a space before the question mark? To obtain a list of commands that begin with a particular character sequence, type in those characters followed immediately by the question mark? Do not include a space. This form of help is called word help, because it completes a word for you. To list keywords or arguments, enter a question mark?

Include a space before the? This form of help is called command syntax help, because it shows you which keywords or arguments are available based on the command, keywords, and arguments you already have entered. You can abbreviate commands and keywords to the number of characters that allow a unique abbreviation. For example, you can abbreviate the configure terminal command to config t. Because the abbreviated form of the command is unique, the router will accept the abbreviated form and execute the command.

Entering the help command available in any command mode will provide the following description of the help system:. As described in the help command output, you can use the question mark? The following example illustrates how the context-sensitive help feature enables you to create an access list from configuration mode.

Enter the letters co at the system prompt followed by a question mark? Do not leave a space between the last letter and the question mark. The system provides the commands that begin with co. Enter the configure command followed by a space and a question mark to list the keywords for the command and a brief explanation:.

In this example, the output indicates that your options for the configure command are configure memory configure from NVRAM , configure network configure from a file on the network , configure overwrite-network configure from a file on the network and replace the file in NVRAM , or configure terminal configure manually from the terminal connection. However, the configure command is a special case, because the CLI will prompt you for the missing syntax:.

The default response for the? Enter the configure terminal command to enter global configuration mode:. For example, the caret symbol in the following output shows the letter that was mistyped in the command:. Enter the access-list command followed by a space and a question mark to list the available options for the command:.

The two numbers within the angle brackets represent an inclusive range. Enter the access list number 99 and then enter another question mark to see the arguments that apply to the keyword and brief explanations:. Enter the deny argument followed by a question mark? Generally, uppercase letters represent variables arguments.

Enter the IP address followed by a question mark? In this output, A. D indicates that use of a wildcard mask is allowed. The wildcard mask is a method for matching IP addresses or ranges of IP addresses. For example, a wildcard mask of 0. Enter the wildcard mask followed by a question mark? Press Enter or Return to execute the command. The system adds an entry to access list 99 that denies access to all hosts on subnet Almost every configuration command has a no form.

In general, use the no form to disable a feature or function. Use the command without the no keyword to reenable a disabled feature or to enable a feature that is disabled by default. For example, IP routing is enabled by default. To disable IP routing, use the no ip routing form of the ip routing command.

To reenable it, use the plain ip routing form. The Cisco IOS software command reference publications describe the function of the no form of the command whenever a no form is available. Many CLI commands also have a default form. By issuing the default command-name command, you can configure the command to its default setting.

The Cisco IOS software command reference documents generally describe the function of the default form of the command when the default form performs a different function than the plain and no forms of the command. To see what default commands are available on your system, enter default?

This feature is particularly useful for recalling long or complex commands or entries, including access lists. To use the command history feature, perform any of the tasks described in the following sections:. The following subsections describe these features:. The table below shows the key combinations or sequences you can use to move the cursor on the command line to make corrections or changes.

Ctrl indicates the Control key, which must be pressed simultaneously with its associated letter key. Esc indicates the Escape key, which must be pressed first, followed by its associated letter key. Keys are not case sensitive. Many letters used for CLI navigation and editing were chosen to provide an easy way of remembering their functions. Left Arrow or Ctrl - B. B ack character. Moves the cursor one character to the left. When you enter a command that extends beyond a single line, you can press the Left Arrow or Ctrl-B keys repeatedly to scroll back toward the system prompt and verify the beginning of the command entry, or you can press the Ctrl-A key combination.

Right Arrow or Ctrl - F. F orward character. Esc , B. B ack word. Esc , F. F orward word. Ctrl - A. Ctrl - E. E nd of line. If you cannot remember a complete command name, or if you want to reduce the amount of typing you have to perform, enter the first few letters of the command, then press the Tab key.

The command line parser will complete the command if the string entered is unique to the command mode. If your keyboard does not have a Tab key, press Ctrl - I instead.

Note that the Esc, Y key sequence will not function unless you press the Ctrl-Y key combination first. If you press Esc, Y more than ten times, you will cycle back to the most recent entry in the buffer.

The CLI provides a wrap-around feature for commands that extend beyond a single line on the screen. When the cursor reaches the right margin, the command line shifts ten spaces to the left. You cannot see the first ten characters of the line, but you can scroll back and check the syntax at the beginning of the command.

To scroll back, press Ctrl-B or the Left Arrow key repeatedly until you scroll back to the beginning of the command entry, or press Ctrl-A to return directly to the beginning of the line. In the following example, the access-list command entry extends beyond one line.

When the cursor first reaches the end of the line, the line is shifted ten spaces to the left and redisplayed. Each time the cursor reaches the end of the line, the line is again shifted ten spaces to the left.

When you have completed the entry, press Ctrl-A to check the complete syntax before pressing the Return key to execute the command. If you have a different screen-width, use the terminal width user EXEC command to set the width of your terminal. Use line wrapping in conjunction with the command history feature to recall and modify previous complex command entries.

You can capitalize or lowercase words or capitalize a set of letters with simple key sequences. To change the capitalization of commands, use any of the following key sequences:. Esc , C. Esc , L. Changes the word at the cursor to lowercase.

Esc , U. Each slot begins with 0 and has a unique slot number. For example a modular router with two slots has slot 0 as first slot and slot 1 as second slot. Router's physical interface can be broken down into multiple logical interfaces called sub-interfaces. Once the sub-interface is created router will treat this logical interface just like a physical interface. RIP is a dynamic routing protocol.

Configuring RIP on a Cisco router is given below. The network Toggle navigation. Command Line Interface CLI The CLI is a character or text based interface used to configure or monitor the deviceit supports a command parser, whenever enter is pressed after typing the command IOS parses the command and parameters that you enterd and checks for correct syntax.. This mode is identified be the prompt as " ". R1 In this mode, we can also use the User EXEC mode commands, this mode has more advanced management and troubleshooting commands.
