Configuring a Virtual Chassis with a Nonprovisioned Configuration File
Copyright © 2010, Juniper Networks, Inc.
NOTE: The properties that you specify for SWA-0 apply to the entire
Virtual Chassis configuration, including all the member listed in the
preprovisioned configuration file.
Configure SWA-0 with the virtual management Ethernet (VME) interface for
6.
out-of-band management of the Virtual Chassis configuration, if desired.
[edit]
user@SWA-0# set interfaces vme unit 0 family inet address /ip-address/mask/
Specify the preprovisioned configuration mode:
7.
[edit virtual-chassis]
user@SWA–0# set preprovisioned
Specify all the members that you want to included in the Virtual Chassis configuration,
8.
listing each switch's serial number with the desired member ID and the desired role:
[edit virtual-chassis]
user@SWA–0# set member 0 serial-number abc123 role routing-engine
user@SWA–0# set member 1 serial-number def456 role linecard
user@SWA–0# set member 2 serial-number ghi789 role linecard
user@SWA–0# set member 3 serial-number jkl012 role linecard
user@SWA–0# set member 4 serial-number mno345 role linecard
user@SWA–0# set member 5 serial-number pqr678 role routing-engine
user@SWA–0# set member 6 serial-number stu901 role linecard
user@SWA–0# set member 7 serial-number vwx234 role linecard
user@SWA-0# set member 8 serial-number yza567 role linecard
user@SWA–0# set member 9 serial-number bcd890 role linecard
Power on the member switches.

NOTE: You cannot modify the mastership-priority when you are using a
preprovisioned configuration. The mastership priority values are generated
automatically and controlled by the role that is assigned to the member
switch in the configuration file. The two routing engines are assigned the
same mastership priority value. However, the member that was powered on
first has higher prioritization according to the master election algorithm. See
"Understanding How the Master in a Virtual Chassis Configuration Is Elected"
on page 928.
