Configuring a Switch as a DHCP Server (CLI Procedure)
NOTE: This topic applies to Junos OS for EX Series switches and QFX Series
switches with support for the Enhanced Layer 2 Software (ELS) configuration
style. If your switch runs software that does not support ELS, see Configuring
a DHCP Server on Switches (CLI Procedure). For ELS details, see Getting
Started with Enhanced Layer 2 Software.
A Dynamic Host Configuration Protocol (DHCP) server provides a framework to pass
configuration information to client hosts on a TCP/IP network. A switch acting as a DHCP
