Description

This article describes the issue of the request system zeroize not removing the virtual chassis from the mixed mode.

Symptoms

Several EX-series devices support the Mixed mode of the virtual chassis. When the mixed mode is enabled, you will see the following output: 

root@EX4200> show virtual-chassis

Virtual Chassis ID: 4eac.87c9.d408
Virtual Chassis Mode: Mixed
                                           Mstr           Mixed Neighbor List
Member ID  Status   Serial No    Model     prio  Role      Mode ID  Interface
0 (FPC 0)  Prsnt    BM0208479584 ex4200-24t 128  Master*      Y
To erase the contents of the log and configuration files, you can use the request system zeroize command on the Mixed mode enabled chassis. However, even when this command is used, you will notice that it does not remove the virtual chassis from the mixed mode.

Solution

This behavior occurs when the command is executed to start the configuration afresh and it is expected that the virtual chassis will still be successfully formed.

If you use the request system zeroize command and want to remove the virtual chassis from the mixed mode, manually disable it as follows: 

root@EX4200> request virtual-chassis mode mixed disable
fpc0:
--------------------------------------------------------------------------
Mixed Mode: Enabled (Configured mode is Disabled, reboot is required to take effect)

root@EX4200> request system reboot
Reboot the system ? [yes,no] (no) yes
