Configuration Statements and Identifiers

You configure all router properties by including statements in the configuration. A statement consists of a keyword, which is fixed text, and, optionally, an identifier. An identifier is an identifying name that you define, such as the name of an interface, or a username, which allows you and the CLI to discriminate among a collection of statements.

Table 12 describes top-level CLI configuration mode statements.

Table 12: Configuration Mode Top-Level Statements

Statement

Description

access

Configure the Challenge Handshake Authentication Protocol (CHAP). For information about the statements in this hierarchy, see the JUNOS System Basics Configuration Guide.

accounting-options

Configure accounting statistics data collection for interfaces and firewall filters. For information about the statements in this hierarchy, see the JUNOS Network Management Configuration Guide.

chassis

Configure properties of the router chassis, including conditions that activate alarms and SONET/SDH framing and concatenation properties. For information about the statements in this hierarchy, see the JUNOS System Basics Configuration Guide.

class-of-service

Configure class-of-service parameters. For information about the statements in this hierarchy, see the JUNOS Class of Service Configuration Guide.

firewall

Define filters that select packets based on their contents. For information about the statements in this hierarchy, see the JUNOS Policy Framework Configuration Guide.

forwarding-options

Define forwarding options, including traffic sampling options. For information about the statements in this hierarchy, see the JUNOS Network Interfaces Configuration Guide.

groups

Configure configuration groups. For information about statements in this hierarchy, see the JUNOS System Basics Configuration Guide.

interfaces

Configure interface information, such as encapsulation, interfaces, virtual channel identifiers (VCIs), and data-link connection identifiers (DLCIs). For information about the statements in this hierarchy, see the JUNOS Network Interfaces Configuration Guide.

policy-options

Define routing policies, which allow you to filter and set properties in incoming and outgoing routes. For information about the statements in this hierarchy, see the JUNOS Policy Framework Configuration Guide.

protocols

Configure routing protocols, including Border Gateway Protocol (BGP), Intermediate System-to-Intermediate System (IS-IS), Label Distribution Protocol (LDP), Multiprotocol Label Switching (MPLS), OSPF, Routing Information Protocol (RIP), and Resource Reservation Protocol (RSVP). For information about the statements in this hierarchy, see the chapters that discuss how to configure the individual routing protocols in the JUNOS Routing Protocols Configuration Guide and the JUNOS MPLS Applications Configuration Guide.

routing-instances

Configure multiple routing instances. For information about the statements in this hierarchy, see the JUNOS Routing Protocols Configuration Guide.

routing-options

Configure protocol-independent routing options, such as static routes, autonomous system numbers, confederation members, and global tracing (debugging) operations to log. For information about the statements in this hierarchy, see the JUNOS Routing Protocols Configuration Guide.

security

Configure IP Security (IPSec) services. For information about the statements in this hierarchy see the JUNOS System Basics Configuration Guide.

snmp

Configure Simple Network Management Protocol (SNMP) community strings, interfaces, traps, and notifications. For information about the statements in this hierarchy, see the JUNOS Network Management Configuration Guide.

system

Configure systemwide properties, including the hostname, domain name, Domain Name System (DNS) server, user logins and permissions, mappings between hostnames and addresses, and software processes. For information about the statements in this hierarchy, see the JUNOS System Basics Configuration Guide.

For specific information on configuration statements, see the JUNOS configuration guides.
