The Virtual Chassis technology enables you to connect multiple individual switches together to form one logical unit and to manage the individual switches as a single unit. You can configure and manage a Virtual Chassis using the Juniper Mist™ portal. The switches you add to a Virtual Chassis are called members. In a Virtual Chassis...

Virtual Chassis
The Juniper Networks EX2300, EX4650, and QFX5120 switches do not form a Virtual Chassis by default, as these switches don’t have dedicated Virtual Chassis ports (VCPs). Therefore, to create a Virtual Chassis with these switches, you need to use the Form Virtual Chassis option on the Juniper Mist™ portal. The Form Virtual Chassis option applies...
The EX3400, EX4100, EX4100-F, EX4300, EX4400, and EX4600 switches come with dedicated Virtual Chassis ports (VCPs). You can create Virtual Chassis using these switches by connecting them to each other via VCPs. These switches don’t support the Form Virtual Chassis option on the Switches page on the Mist portal.
You can use the Modify Virtual Chassis option on the switch details page to renumber and replace the Virtual Chassis members and add new members to a Virtual Chassis.
You can add one or more member switches to a Virtual Chassis from the Modify Virtual Chassis window.
You can delete the member switches from the Virtual Chassis, by clicking the delete (trash) icon on the Modify Virtual Chassis window. Before deleting any member switch, you must ensure that the switch to be removed is disconnected from the Virtual Chassis
If you prefer to see the Virtual Chassis members on the Mist portal in the same order as they are physically stacked, you need to power these members on and then connect them to the other existing Virtual Chassis switch members in that order.
You can replace a disconnected Virtual Chassis member switch with another, by deleting the old member and adding a new member
Default mastership determination: Member with highest user configured priority (1-155), default is 128. Member previously functioning as master prior to reboot Member with the longest standing time (difference must be greater than 1 minute) Member with the lowest MAC Address (used as a tie breaker if all is equal through the first three determination steps)...
