Prepare SWA-2 in wiring closet B for interconnecting with the Virtual Chassis

configuration by configuring its mastership priority to be the highest possible value
(255). Its member ID is currently
other members of the Virtual Chassis configuration. It is operating as a standalone
switch. Its member ID will change when it is interconnected.
[edit virtual-chassis]
user@SWA-2# set member 0 mastership-priority 255
NOTE: SWA-2 is configured with the same mastership priority value
that we configured for SWA-0. However, the longer uptime of SWA-0
ensures that, once the interconnection is made, SWA-0 functions as
the master and SWA-2 functions as the backup.
Specify one uplink module port in SWA-2 as an uplink VCP. Its member ID is

because it is not yet interconnected with the other members of the Virtual Chassis
configuration.
NOTE: The setting of the uplink VCP remains intact when SWA-2 reboots
and joins the Virtual Chassis configuration as member 2.
user@SWA-2> request virtual-chassis vc-port set pic-slot 1 port 0
Physically interconnect SWA-0 and SWA-2 across wiring closets using their uplink

VCPs. Although SWA-0 and SWA-2 have the same mastership priority value (255),
SWA-0 was powered on first and thus has longer uptime. This results in SWA-0
retaining mastership while SWA-2 reboots and joins the now expanded Virtual
Chassis configuration as the backup, with member ID
Power on SWA-3. It joins the expanded Virtual Chassis configuration as member

NOTE: Member ID
powered on after members 0, 1, and 2.
Because SWA-3 is now interconnected as a member of the Virtual Chassis

configuration, you can specify a redundant uplink VCP on SWA-3 through the master
of the Virtual Chassis configuration:
user@SWA-0> request virtual-chassis vc-port set pic-slot 1 port 0 member 3
Physically interconnect SWA-3 and SWA-1 across wiring closets using their uplink
8.
VCPs. Both SWA-1 and SWA-3 have the default mastership priority value (128) and
function in a linecard role.
