Switch Uplink Module Port as a Virtual Chassis Port (CLI Procedure)" on page 994.
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
configuration changes made for a Virtual Chassis. This ensures that the
configuration changes are saved in both Routing Engines.
An EX4200 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.
