OS for EX Series Ethernet Switches, Release 10.3
Interconnect the member switches using the dedicated VCPs on the rear panel of
1.
switches. See Connecting a Virtual Chassis Cable to an EX4200 Switch.
NOTE: Arrange the switches in sequence, either from top to bottom or
from bottom to top (0–9).
Power on only the switch that you plan to use as the master switch (SWA-0). Do not
2.
power on the other switches at this time.
Run the EZ Setup program on SWA-0, specifying the identification parameters. See
3.
"Connecting and Configuring an EX Series Switch (CLI Procedure)" on page 187 for
details.
NOTE: The properties that you specify for SWA-0 apply to the entire
Virtual Chassis configuration, including all the members interconnected
through VCPs..
Configure SWA-0 with the virtual management Ethernet (VME) interface for

out-of-band management of the Virtual Chassis configuration, if desired.

Power on the member switches in sequential order, one by one.

NOTE: If you do not edit the Virtual Chassis configuration file, a
nonprovisioned configuration is generated by default. The mastership priority
value for each member switch is
You can change the role that is performed by the members by modifying the
mastership-priority. See "Configuring Mastership of the Virtual Chassis (CLI
Procedure)" on page 1021. We recommend that you specify the same mastership
priority value for the desired master and backup members. We have assigned
the highest possible mastership priority to two members. 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. We have allowed the other
members to use the default mastership priority, which qualifies them to
function in the role of linecard.
. The master role is selected by default.
