Using the no Version Versus the default Version of Commands

Most router configuration commands have a no version, which you can use to negate a command (or a portion of it specified by an optional keyword) or restore its default setting. When you use a command without the keyword no, you can reenable a disabled feature or override a default setting. You have the option of using the default keyword whenever the no keyword is also a choice; simply enter the keyword default instead of no.

In most cases, when you execute the default version of a command, it produces the exact results as the no version. There are some commands for which the default version yields a different result than the no version.

Commands for which the default behavior differs from the no behavior are clearly identified in this guide. Unless otherwise specified, therefore, the default command is identical to the no command and is neither documented nor discussed.

The syntax for each no command is described in this guide. Some commands do not have a no version; this is indicated in the individual command descriptions except for the show commands, none of which has a no version.

The CLI can act on no versions of commands when you have entered sufficient information to distinguish the command syntactically, and ignores all subsequent input on that line.

To be compatible with some non–E-series implementations, the no versions of commands accept the same options as the affirmative version of the commands. The CLI ignores the optional input if it has no effect on the command behavior. If using the option changes the behavior of the no version, the individual command entry in this guide describes the difference in behavior.

Deprecated Commands

A command that has been deprecated in a release or in a particular configuration mode returns a notice when you issue the command manually:

NOTICE: This command is obsolete. It may be completely removed from a 
subsequent software release.

A preferred alternate command is provided in the notice. If you have a script that uses the deprecated command, the deprecated command is automatically mapped to the preferred command when you run the script. If the deprecated command no longer has a function, then that command has no effect when you run a script containing the command.

We recommend that you use the preferred command when writing new scripts.

Filtering show Commands

You have access to a variety of show commands that display router and protocol information. You can filter the output of a show command by specifying | (the UNIX pipe symbol), one of the following keywords, and either a case-sensitive text string or a regular expression.

begin—Displays output beginning with the first line that contains the text string or regular expression
include—Displays output lines that contain the text string or regular expression and excludes lines that do not contain the text string or regular expression
exclude—Displays output lines that do not contain the text string or regular expression and excludes lines that do contain the text string or regular expression

For a list of regular expressions, see JUNOSe IP Services Configuration Guide, Chapter 1, Configuring Routing Policy.

You can press Ctrl+c to interrupt the show command output.

NOTE: The router does not recognize beginning spaces of the text string. For example, if you enter the include option with IP as the text string on which to filter, the router ignores the space and displays lines that include words such as RIP.

Example

In the following example, the output display consists only of lines that contain the string ip. The router omits all other lines of the output from the display because none of them contain the string ip.

Interface Types and Specifiers

Many commands take the variables interfaceType and interfaceSpecifier. Some commands support all types of interfaces, whereas other commands support only certain types of interfaces. Similarly, some commands support all interface specifier formats for a particular interface type, whereas other commands support only certain interface specifier formats.

Table 3 lists the interface specifiers for each type of interface on ERX-7xx models, ERX-14xx models, and the ERX-310 router.

Table 4 lists the interface specifiers for each type of interface on the E120 router and the E320 router.

  Footnote: ¹You can use the atm slot/port/vpi/vci interface specifier format as an alternative to the atm slot/port.subinterface format with the specific show interface and show subinterface commands to monitor all ATM 1483 subinterfaces (except NBMA interfaces) as well as the upper-layer interfaces configured over an ATM 1483 subinterface. You cannot, however, use the atm slot/port/vpi/vci format to create or modify an ATM 1483 subinterface.
  Footnote: ²You cannot configure values on the null interface. This interface acts as a data sink; it cannot forward or receive traffic.

  Footnote: ¹You can use the atm slot/adapter/port/vpi/vci interface specifier format as an alternative to the atm slot/adapter/port.subinterface format with the specific show interface and show subinterface commands to monitor all ATM 1483 subinterfaces (except NBMA interfaces) as well as the upper-layer interfaces configured over an ATM 1483 subinterface. You cannot, however, use the atm slot/adapter/port/vpi/vci format to create or modify an ATM 1483 subinterface. 
  Footnote: ²You cannot configure values on the null interface. This interface acts as a data sink; it cannot forward or receive traffic.
