Description

This article describes the issue of the format installation does not remove the virtual chassis from the mixed mode.

Symptoms

EX4300-48T supports the Mixed mode of the virtual chassis. When the mixed mode is enabled, you will see the following output:
 

root@EX4300-48T> show virtual-chassis

Virtual Chassis ID: 0000.0000.0001
Virtual Chassis Mode: Mixed
                                                Mstr           Mixed               Route Neighbor List
Member ID  Status   Serial No    Model          prio  Role      Mode               Mode ID  Interface

To initialize the device, you can use the format installation. However, even when the fomat installation is executed, 
you will notice that it does not remove the virtual chassis from the mixed mode.

Solution

This behavior occurs after the format installation is executed to initialize the device and it is expected that the virtual chassis will still be successfully formed.
If you use the format installation and want to remove the virtual chassis from the mixed mode, manually disable it as follows:

 

root@EX4300-48T> request virtual-chassis mode mixed disable
fpc0:
--------------------------------------------------------------------------
Mixed Mode: Enabled (Configured mode is Disabled, reboot is required to take effect)

root@EX4300-48T> request system reboot
Reboot the system ? [yes,no] (no) yes
