System Basics: System Services Configuration Guide

Junos OS enables you to configure common system services for communication between devices connected to IP networks, including the Dynamic Host Configuration Protocol (DHCP) for IP address management and services for remote access to devices using Telnet, FTP, NETCONF, and other system services. Use the topics on this page to configure essential system services on your devices running Junos OS.
