Configuring Automatic Software Update on Virtual Chassis Member Switches (CLI Procedure)

The automatic software update feature allows you to automatically update the software version on prospective member switches as they are added so that they can join the Virtual Chassis.

Note: The version of Junos OS running on the Virtual Chassis must be compatible with the software running on the prospective member switch for an automatic software update to occur. For information on Junos OS compatibility and other automatic software update restrictions, see Understanding Automatic Software Update on Virtual Chassis Member Switches.

Before you begin, ensure that you know the name or the URL of the software package to be used by the automatic software update feature.

To configure the automatic software update feature for an EX Series or QFX Series Virtual Chassis with the exception of a mixed Virtual Chassis containing at least one EX4200 switch and at least one EX4500 or EX4550 switch:

[edit]
user@switch# set virtual-chassis auto-sw-update package-name package-name

To configure the automatic software update feature on a mixed Virtual Chassis containing at least one EX4200 switch and at least one EX4500 or EX4550 switch:

[edit]
user@switch# set virtual-chassis auto-sw-update ex-4200 package-name package-name
user@switch# set virtual-chassis auto-sw-update ex-4500 package-name package-name

If the software package is located on a local directory on the switch, use the following format for package-name:

/pathname/package-name

If the software package is to be downloaded and installed from a remote location, use one of the following formats:

ftp://hostname/pathname/package-name

ftp://username:prompt@ftp.hostname.net/package-name

http://hostname/pathname/package-name

If you are configuring a mixed Virtual Chassis containing at least one EX4200 switch and at least one EX4500 or EX4550 switch, use the ex-4200 keyword when you are specifying a path to a package for the EX4200 switches and the ex-45o0 when you are specifying a path to a package for the EX4500 or EX4550 switches. You do not need to specify the ex4500 keyword when configuring automatic software update for a mixed EX4500 and EX4550 Virtual Chassis, however, because the Junos OS package for an EX4500 switch updates the software for both EX4500 and EX4550 switches.
