Troubleshooting
To troubleshoot a Virtual Chassis configuration that is interconnected across wiring
closets, perform this task:
Troubleshooting Nonoperational VCPs
Problem
An uplink VCP shows a status of
down
.
Solution
Check the cable to make sure that it is properly and securely connected to the interfaces.
•
•
If the VCP is an uplink module interface, make sure that it has been explicitly set as an
uplink VCP.

Example: Configuring Automatic Software Update on Virtual Chassis Member Switches
The automatic software update feature automatically updates the Juniper Networks
Junos OS version on prospective member switches as they are added to a Virtual Chassis
configuration of Juniper Networks EX4200 Ethernet Switches so the new member switch
immediately joins the Virtual Chassis configuration and is put in the active state. If the
software version on the new switch is not the same as the version running on the master,
the master keeps the new switch in the inactive state. If you have not enabled the
automatic software update feature, you will have to manually install the correct software
version on each prospective member switch as it is added to the Virtual Chassis
configuration.
This example describes how to configure the Virtual Chassis automatic software update
feature:
