NOTE:
A multimember Virtual Chassis configuration has two Routing Engines,
one in the master and the other in the backup. Therefore, we recommend
that you always use commit synchronize rather than simply commit to save
configuration changes made for a Virtual Chassis. This ensures that the
configuration changes are saved in both Routing Engines.
A Virtual Chassis can be configured with either:
•
preprovisioned configuration—Allows you to deterministically control the member ID
and role assigned to a member switch by tying it to its serial number.
•
nonprovisioned configuration—The master sequentially assigns a member ID to other
member switches. The role is determined by the mastership priority value and other
factors in the master election algorithm.

Configuring a Virtual Chassis with a Preprovisioned Configuration File
To configure a Virtual Chassis using a preprovisioned configuration:
1.
Make a list of the serial numbers of all the switches to be connected in a Virtual Chassis
configuration.
2.
Note the desired role (
routing-engine
or
linecard
) of each switch. If you configure the
member with a
routing-engine
role, it is eligible to function as a master or backup. If
you configure the member with a
linecard
role, it is not eligible to become a master
or backup.
3.
Interconnect the member switches using the dedicated VCPs on the rear panel of
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).
4.
Power on only the switch that you plan to use as the master switch (SWA-0). Do not
power on the other switches at this time.
5.
Run the EZ Setup program on SWA-0, specifying the identification parameters. See
“Connecting and Configuring an EX Series Switch (CLI Procedure)” on page 187 for
details.
