NOTE: To revert a member switch of a Virtual Chassis to the factory-default conguraon,
disconnect the cables connected to the VCPs to avoid aecng Virtual Chassis conguraon
parameters (member ID, primary-role priority, and seng of VCP uplinks) on other members (see
Disconnect a Fiber-Opc Cable ).
You can revert to the factory-default conguraon by using the request system zeroize operaonal
command or the load factory-default conguraon command. You can also use the load factory-default
command to revert to the factory-default conguraon le that contains all default sengs except the
root password seng, which is retained.
We describe these procedures in the following secons:
Revert to the Factory-Default Conguraon by Using the request system zeroize
Command
The request system zeroize command is a standard Junos OS operaonal mode command that removes all
conguraon informaon and resets all key values. The operaon unlinks all user-created data les,
including customized conguraon and log les, from their directories. The switch then reboots and
reverts to the factory-default conguraon.
To completely erase user-created data so that it is unrecoverable, use the request system zeroize media
command.
CAUTION: Before issuing request system zeroize, use the request system snapshot command
to back up the les currently used to run the switch to a secondary device.
1. To revert to the factory-default conguraon by using the request system zeroize command:
user@switch> request system zeroize warning: System will be rebooted and may not boot without
configurationErase all data, including configuration and log files? [yes,no]
(yes)
2. Type yes to remove conguraon and log les and revert to the factory-default conguraon.
NOTE: The auto-image-upgrade statement is added at the [edit chassis] hierarchy level when you
use this procedure. Thus, the automac image upgrade feature is made available on the
switch.
