Release Information

Statement introduced in Junos OS Release 9.6 for EX Series switches.


Enable automatic software download on an EX Series switch acting as a DHCP client.

The DHCP client EX Series switch compares the software package name in the DHCP server message to the name of the software package that booted the switch. If the software packages are different, the DHCP client EX Series switch downloads and installs the software package specified in the DHCP server message.

Before you upgrade software using automatic software download, ensure that you have configured DHCP services for the switch, including configuring a path to a boot server and a boot file. See the Junos OS System Basics Configuration Guide for information about using the CLI to configure DHCP services and settings.


Automatic software download is disabled.
