Statement introduced in Junos OS Release 9.0 for EX Series switches.
Statement introduced in Junos OS Release 13.2X50-D15 for the QFX Series.
Statement introduced in Junos OS Release 13.2X51-D20 for Virtual Chassis Fabric (VCF).
Specify the roles of the members of the Virtual Chassis or a Virtual Chassis Fabric (VCF)
in a preprovisioned Virtual Chassis.
Virtual Chassis Fabric
Specify the role to be performed by each switch. In a VCF, two spine devices are configured
into the Routing Engine role and the remaining spine devices and all leaf devices are
configured into the line-card role. The role must be associated with the member's serial
number.
EX Series (except EX8200 Virtual Chassis) and QFX Series Virtual Chassis
Specify the role to be performed by each member switch. Associate the role with the
member's serial number.
When you use a preprovisioned configuration, you cannot modify the mastership priority
or member ID of member switches through the user interfaces. The mastership priority
value is generated by the software, based on the assigned role:
A member configured as
A member configured as
A member listed in the preprovisioned configuration without an explicitly specified role
is assigned the line-card role and mastership priority
The configured role specifications are permanent. If both
a line-card member cannot take over as master of the Virtual Chassis configuration. You
must delete the preprovisioned configuration to change the specified roles in a Virtual
Chassis.
Explicitly configure two members as
as members of the preprovisioned Virtual Chassis by specifying only their serial numbers.
If you do not explicitly configure the role of the additional members, they function in a
line-card role by default. In that case, a member that is functioning in a line-card role can
take over mastership if the members functioning as master and backup (
role) both fail.
