The show config command is used to display various aspects of a text-based configuration that is stored in the device or being modified. For information about the format and syntax of the configuration, please refer to the manual page for each section of the configuration. The list command in the configuration editor uses the same options as show config, except for the section_name, which is implied by the section you are in when you use list. See the "Configure Command" section to enter the configuration editor.
show config [help | list | number |
section_name | The section_name must be a valid configuration section and must be fully spelled out in order to be found. If no section name is specified, the entire device configuration will be displayed. |
help | The help option is used to generate a message showing all of the options available and a short description of how the option is used. |
list | The list option will generate a list of section names known to the device. Not all devices understand all sections listed in this manual, because configuration information is dependent on which features a device has. |
number | The number option will cause line numbers to be printed as the configuration is displayed. |
cook | Cooked mode is used to display different aspects of the configuration. In cooked mode, the configuration will be reformatted and reordered, and comments will be stripped out of port-specific and general configuration sections. Cooked mode must be enabled using the cook option. Once the cook option has been specified, the configuration parser will be run causing the configuration to be checked for errors as it is being displayed. The following options may be used with the cook option to tailor the display or find out different information.

In addition to simply displaying a configuration, these commands can be used to:
A configuration can be displayed using one of the two basic modes, raw and cooked. Raw mode is the default way a configuration or section of a configuration will be displayed. In this mode, the configuration will be displayed exactly as it is stored in the device's permanent configuration memory, or, in the case of an edited configuration, as it exists in the edit buffer. When a configuration is displayed using cooked mode, the device will run the raw configuration through a parser to check the values in the configuration. This mode is called "cooked" because the data being displayed has been prepared for display.
When editing a configuration, it is possible to run the configuration through the same parsers that the device uses to initialize itself. Use the existing show * config commands (e.g., show ip config) to run these parsers.
The following sections show an example for each command.
The following example displays a raw version of a configuration section.
show config IP WAN 0 [ IP Wan 0 ] RIPVersion = V1 # Turnn RIP on Numbered = TRUE IPAddress = 31.0.0.5 SubnetMask = 255.0.0.0 IPBroadcast = 31.255.255.255 RemoteAddress = 0.0.0.0 Updates = periodic
The next example shows the same section cooked.
show config cook IP WAN 0 [ IP Wan 0 ] Mode = Routed IPAddress = 31.0.0.5 SubnetMask = 255.0.0.0 IPBroadcast = 31.255.255.255 RIPVersion = V1 OutFilters = InFilters = Numbered = On Updates = Periodic RemoteAddress = 0.0.0.0
Notice that the comments have been removed and the configuration has been reformatted. Also notice that several additional keywords have been added to the display. The additional keywords are considered important variables and as such they are displayed in cooked configurations.
The following example shows the same configuration displayed using the mark option.
show config cook mark IP WAN 0 [ IP Wan 0 ] Mode = Routed IPAddress = 31.0.0.5 # Default => 0.0.0.0 SubnetMask = 255.0.0.0 # Default => 0.0.0.0 IPBroadcast = 31.255.255.255 # Default => 0.0.0.0 RIPVersion = V1 # Default => None OutFilters = InFilters = Numbered = On # Default => Off Updates = Periodic # Default =>Triggered RemoteAddress = 0.0.0.0
The next sequence of commands illustrates the use of hierarchies and the origin option.
*[ IP Wan 0 ]# configure ip wan default Section 'ip wan default' not found in the config. Do you want to add it to the config? y Configure parameters in this section by entering: <Keyword> = <Value> To find a list of valid keywords and additional help enter "?" *[ IP Wan Default ]# mode = bridged *[ IP Wan Default ]# list [ IP Wan Default ] Mode = Bridged *[ IP Wan Default ]# show config cook origin ip wan 0 # TBM Parser: Looking for: IP Wan 0: Mode # Found in Cfg Buffer, line 231, section 'IP Wan Default' [ IP Wan 0 ] # TBM Parser: Looking for: IP Wan 0: Mode # Found in Cfg Buffer, line 231, section 'IP Wan Default' Mode = Bridged # TBM Parser: Looking for: IP Wan 0: IPAddress # Found in Cfg Buffer, line 26, section 'IP Wan 0' IPAddress = 31.0.0.5 # TBM Parser: Looking for: IP Wan 0: SubnetMask # Found in Cfg Buffer, line 27, section 'IP Wan 0' SubnetMask = 255.0.0.0 # TBM Parser: Looking for: IP Wan 0: IPBroadcast # Found in Cfg Buffer, line 28, section 'IP Wan 0' IPBroadcast = 31.255.255.255
Display continues for a while...
*[ IP Wan Default ]#
Notice in the preceding display, the value of the Mode keyword is set to Bridged even though it is not set in the [ IP Wan 0 ] section. The display shows which line and in which section all of the keywords were found.
| Command | Description |
|---|---|
configure | Enters the configuration editor, which allows you to add or modify configuration variables using keyword and value pairs and ensures that they are syntactically correct |
