Description

Enable the automatic software update feature for Virtual Chassis or Virtual Chassis Fabric (VCF) configurations.

You should only use the keywords that specify a device or device family—ex-4300, ex-4600, qfx-3, and qfx-5—when configuring automatic software update on a mixed mode Virtual Chassis or Virtual Chassis Fabric (VCF). You can simply specify the package-name without specifying individual device keywords in non-mixed Virtual Chassis or VCF topologies.

Note:

The automatic software update feature is not supported for a mixed mode EX4300 Virtual Chassis with a combination of EX4300 multigigabit model (EX4300-48MP) switches and other EX4300 switches.

You must enter the auto-sw-update statement multiple times—once for each device family in your mixed Virtual Chassis or VCF—in most scenarios when enabling the automatic software update for a mixed Virtual Chassis or VCF.

The Junos OS package for an EX4500 switch updates the software for EX4500 and EX4550 switches. You do not, therefore, need to specify the ex-4500 keyword when configuring automatic software update for a mixed Virtual Chassis that include EX4500 and EX4550 switches only. You also only have to enter the ex-4500 keyword once to configure automatic software update for all EX4500 and EX4550 member switches in the s37628)ame mixed Virtual Chassis.

The Junos OS package for a QFX3500 device updates the software for QFX3500 and QFX3600 devices. You do not, therefore, need to specify the qfx-3 keyword when configuring automatic software update for a Virtual Chassis composed entirely of QFX3500 and QFX3600 devices. You also have to enter the qfx-3 keyword only once to configure automatic software update for all QFX3500 and QFX3600 member devices in the same mixed Virtual Chassis.

The Junos OS package for a QFX5110 device updates the software for both QFX5110 and QFX5100 devices in a QFX5110 Virtual Chassis or VCF, so you do not need to specify the qfx-5 keyword when configuring automatic software update for a QFX5110 Virtual Chassis or VCF composed of both types of devices.

CAUTION:

A QFX5100 switch running a Junos OS software image with “-qfx-5-” in the package filename must first be upgraded to a Junos OS software image with “-qfx-5e-” in the package filename before it can be added to a mixed QFX5110 Virtual Chassis or VCF. The automatic software update process cannot update a switch from a “-qfx-5-” image to a “-qfx-5e-” image. See Upgrading a QFX5100 Switch with a USB Device to Join a QFX5110 Virtual Chassis or Virtual Chassis Fabric.

After a QFX5100 switch is installed with a “-qfx-5e-” Junos OS software image, the automatic software update process can successfully update the switch automatically with a different version of a “-qfx-5e-” Junos OS image to match the other members in the Virtual Chassis or VCF.

The remaining statement is explained separately. See CLI Explorer.

Default

The automatic software update feature is disabled.

Options

package-name `package-name`	Specify the software package name or a path to a Junos OS software image to update new members being added to a Virtual Chassis or VCF. . 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 file access and transfer formats: `ftp://hostname/pathname/package-name` `ftp://username:prompt@ftp.hostname.net/package-name` `http://hostname/pathname/package-name`
ex-4200	Specify a path to a Junos OS image for an EX4200 switch when enabling automatic software update for a mixed EX4200 and EX4500 Virtual Chassis, mixed EX4200 and EX4550 Virtual Chassis, or mixed EX4200, EX4500, or EX4550 Virtual Chassis.
ex-4300	Specify a path to a Junos OS image for an EX4300 switch when enabling automatic software update for a mixed Virtual Chassis or VCF. Automatic software update is not supported for mixed mode EX4300 Virtual Chassis with a combination of EX4300 multigigabit model (EX4300-48MP) switches and other EX4300 switches, and this option is not applicable in that case.
ex-4500	Specify a path to a Junos OS image for an EX4500 switch, an EX4550 switch, or both types of switches when enabling automatic software update for a mixed EX4200 and EX4500 Virtual Chassis, mixed EX4200 and EX4550 Virtual Chassis, or mixed EX4200, EX4500, or EX4550 Virtual Chassis. The Junos OS package for an EX4500 switch updates the software for EX4500 and EX4550 switches. Therefore, you only enter this command once to upgrade the EX4500 and EX4550 member switches in the same mixed Virtual Chassis. The `ex-4500` keyword also does not need to be specified when configuring automatic software update for a mixed EX4500 and EX4550 Virtual Chassis.
ex-4600	Specify a path to a Junos OS image for an EX4600 switch when enabling automatic software update for a mixed Virtual Chassis.
qfx-3	Specify a path to a Junos OS image for a QFX3500, QFX3600, or both types of devices when enabling automatic software update for a mixed Virtual Chassis or VCF.
qfx-5	Specify a path to a Junos OS image for a QFX5100 device when enabling automatic software update for a mixed QFX5100 Virtual Chassis or VCF. You do not need to use this option for a QFX5110 Virtual Chassis or VCF that contains both QFX5110 and QFX5100 switches because the same software image runs on either type of switch.
