2.1.3 startup-config and running-config

The configuration information is saved to startup-config and running-config files. This section describes the functions of the startup-config and running-config files.

z startup-config

Startup-config is the configuration file that stores the environment settings that are enabled upon device startup. The startup-config is saved in non-volatile memory and read the next time the device is reset or power cycled.

z running-config

Running-config is a file stored in volatile memory that represents the operating environment of the current running system. The information stored in the running-config file will be lost when the system is restarted. To assure the system configuration that is active in the current running-config file is enabled the next time the system is started, use the "copy" command to save it to the startup-config file.

xg# copy running-config startup-config

The contents of the startup-config and running-config match immediately after the device is started.

z How to upload and save the startup-config and running-config files

To upload the configuration information to the remote server, run the "show" command.

xg# show running-config | tftp HOST REMOTE-FILE

xg# show startup-config | tftp HOST REMOTE-FILE

xg# show running-config | scp USERNAME HOST REMOTE-FILE

xg# show startup-config | scp USERNAME HOST REMOTE-FILE

z How to download startup-config

To download the configuration information that was uploaded to the remote server as startup-config, run the "copy" command.

xg# copy tftp HOST REMOTE-FILE startup-config

xg# copy scp USERNAME HOST REMOTE-FILE startup-config

To enable the settings downloaded to the startup-config file, restart the device using the "reset" command.

2.2 Using the CLI

2.2.1 How to Enter Commands

z Command Entry Format

Separate each command, subcommand and argument with a single space.

<command> <subcommand> <argument 1> <argument 2> ... (" " indicates a space.)

xg(config)# management-interface ip 192.168.1.10/24 default-gw 192.168.1.150 xg(config)# management-interface dns-server 192.168.1.150

z Characters that can be entered:

− Any letter (A-Z, a-z) and digit (0-9)

− Space (ASCII code: 0x20)

− Symbols: !, ". #, $, %, `, ', (, ), _, -, ~, ^, ¥, {, }, :, +, ,, ., @, =, [, ], &, *, ;, /, ?, |, >

Command and option separators are recognized as one or more space characters (ASCII code: 0x20). Enclose a parameter in quotes if it contains a blank space. The commands are not case-sensitive. Note that some entries (password, etc.) are case-sensitive.

2.2.2 Context-Sensitive Help

Entering a question mark "?" at the command prompt displays a list of commands available for each command mode. A list of command's associated with the keywords and parameters will be displayed.

z A list of commands that are available in the current mode

Entering a question mark "?" at the system prompt displays a list of commands and brief descriptions available for the current command mode.

xg # ? Exec commands: boot-system Change firmware to boot clear Reset functions configure Enter configuration mode copy Copy from one file to another date Manage the system date and time delete Delete files on current system dir List files on current system :

(The rest is omitted.)

xg# _

z Word help

Entering a question mark "?" in the middle of a command name, will list the possible command options required to complete the command. The prompt will show the letters previously typed. Enter the rest of the letters to complete the command entry.

xg # co? Exec commands: configure Enter configuration mode copy Copy from one file to another xg# co_

The CLI lists all possible commands that begin with "co".

z A list of options that are available in the current entry position

Entering a question mark "?" followed by a space after typing a command name, will cause the CLI to list the possible commands or keywords that may be entered at the current option position. For option 2 and 3 positions, the CLI also lists options that can be entered at these positions. The prompt will show the letters previously typed. Enter the rest of the letters to complete the command entry.

xg# configure ? terminal Configure from the terminal

xg# configure _

CLI lists possible options that follow the "configure" command.

The <cr> symbol may appear in the list to indicate that the command can be executed without entering any subsequent options. Parameters enclosed in square brackets can be omitted and, therefore, the <cr> symbol does not appear.

17/315

XG2000 series User's Guide

2.2.3 Command Completion

Entering part of a command or option and pressing the [Tab] key, causes the CLI to display the remaining command or option characters.

For example, the only command that begins with "con" is "configure", so the CLI completes the command name as "configure". Pressing the [Tab] key, causes the CLI to list all possible commands or option names.

Since there are two commands that begin with "co" - "configure" and "copy" - the CLI lists both commands.

xg# con<TAB> ↓

xg# configure _

xg# co<TAB> configure copy xg# co_

2.2.4 Command Abbreviation

Commands and options can be abbreviated to the minimum number of characters as long as command or option names are unique and forward-match the entered letters.

For example, the "configure" command may be abbreviated to "con" because "configure" is the only command that begins with "con", and "terminal" may be abbreviated to "t" because "terminal" is the only command that begins with "t".

xg# con t

2.2.5 Command-Line Error Messages

The table below shows error messages that appear when a command is incorrectly entered. The "configure terminal" command is used as an example below:

xg# co t % Ambiguous command: "co t"

xg# configure % Incomplete command.

xg# configure aerminal ^ % Invalid input detected at '^' marker

xg# coc? % Unrecognized command

Error Message Explanation

Insufficient characters were entered for the CLI to recognize the command. Re-enter the correct command string. All of the options or values required by this command were not entered. Enter all necessary options and values. The command incorrectly entered. A caret symbol (^) indicates the incorrect entry. Correct the entries and execute the command again. Part of the command was incorrectly entered. Re-enter the correct command string.

2.2.6 Scrolling Down or Up a Line or a Page

When the information displayed by a command contains more lines than the console screen will display, a "--More--" prompt is displayed at the bottom of the screen and the CLI waits for a user entry.

The following table shows the combinations of shortcut keys, function keys and the [Ctrl] key used to edit commands.

19/315

XG2000 series User's Guide

2.2.10 Filtering show Command Output

This function allows filtering the show command output so lines that only satisfy specific conditions (filter for strings) are displayed. This function is useful in excluding unnecessary information from a large amount of output. To use it, a "show" command must be followed by a keyword (pipe (|), begin, include or exclude) and a regular expression (filtering condition).

Syntax

show       | {begin | include | exclude} regular-expression

Keyword for filtering output Meaning

begin

exclude include

xg# show history | begin 2 ...skipping 2 configure terminal 3 show running-config 4 show history 5 show history | begin 2

xg# show history | exclude 2 1 enable 3 show running-config 4 show history

xg# show history | include 2 2 configure terminal 5 show history | begin 2

Begins output starting at the first line that contains matches to given regular expression parameters. Does not display output lines that contain matches to given regular expression parameters. Displays output lines that contain matches to given regular expression parameters.

Regular expressions are case sensitive. For example, if "| exclude strings" is entered, lines that include "String" are output, but those that include "strings" are not.

2.2.11 Redirecting show Command Output

Redirect the output of "show" commands to a file in volatile memory using ">" (pipe) or "|” (redirect).

show       > FILE-NAME show       | FILE-NAME

z FILE-NAME

Specifies the file name in volatile memory that the output of the command is piped or redirected.

"| tftp" or "| scp" redirects the output of the show command to a file on a remote server.

show       | tftp HOST REMOTE-FILE

show       | scp USERNAME HOST REMOTE-FILE

z | tftp

Redirects the copy to a file on the TFTP server.

z | scp

Redirects the copy to a file on the SSH server.

z USERNAME

Specifies the username of the SSH server.

z HOST

Specifies the host name or IP address of the TFTP server or SSH server.

z REMOTE-FILE

Specifies the file name in the TFTP server or SSH server that the output of the command is redirected.

In the following example, the current startup-config is redirected as filename "startup_09302005", the running-config file is redirected as filename "running_09302005", and system information is redirected as filename "system_09302005". The results of the redirection are confirmed with the "ls" command. Then, using the "tftp" command, each of these files are moved to the TFTP server.

xg# show startup-config > startup_09302005 xg# show running-config > running_09302005 xg# show system information > system_09302005 xg# ls
