About This Guide
This Command Reference Guide provides all the commands available to configure your system. Refer to the configuration guides for detailed information on configuring your ERX system.
Note: If the information in the latest Release Notes differs from the information in this guide, follow the Release Notes.![]()
Your ERX system is shipped with the latest system software installed. If you need to install a future release or reinstall the system software, refer to the procedures in ERX Installation and User Guide, Appendix E, Installing ERX System Software.
ERX Edge Routers
Four models of ERX edge router are available:
All models use the same software. For information about the differences between the models, see ERX Installation and User Guide, Chapter 1, ERX System Overview.
In the ERX documentation, the term ERX-1400 series refers to both the ERX-1440 system and the ERX-1400 system. Similarly, the term ERX-700 series refers to both the ERX-705 system and the ERX-700 system. The terms ERX-1440 system, ERX-1400 system, ERX-705 system, and ERX-700 system refer to the specific models.
Audience
This guide is intended for experienced system and network specialists who will configure a Juniper Networks ERX system in an Internet access environment.
Conventions
Table 1, Table 2, and Table 3 list all the conventions used in the ERX documentation. Table 1 defines notice icons. Table 2 shows text conventions used throughout the book, except for command syntax. Table 3 provides command syntax conventions used primarily in the ERX Command Reference Guide. For more information about command syntax, see ERX System Basics Configuration Guide, Chapter 1, Planning Your Network.

Using the no vs. the default Version of Commands
Most system 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 will neither be 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-ERX implementations, the no versions of commands will 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.
Filtering show Commands
You have access to a variety of show commands that display system 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 ERX Routing Protocols Configuration Guide, Vol. 1, Chapter 1, Configuring Routing Policy.
You can press <Ctrl+C> to interrupt the show command output.
Note: The system 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 system 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 system omits all other lines of the output from the display because none of them contain the string ip.

Many commands take the variables interfaceType and interfaceSpecifier. Some commands support all types of interfaces, whereas other commands support only certain types of interfaces. The interface specifier depends on the type of interface. Table 4 shows the interface specifiers for each type of interface.
