Adding a New Switch to an Existing Virtual Chassis Configuration (CLI Procedure)
You can add one or more EX4200 switches to an existing Virtual Chassis configuration.
Up to ten EX4200 switches can be included within a Virtual Chassis configuration. You
can add the new switches to either type—nonprovisioned or preprovisioned—of Virtual
Chassis configuration. See Configuring a Virtual Chassis (CLI Procedure) for descriptions
of these types.
To add a switch to an existing Virtual Chassis configuration, use the procedure that
matches what you need to accomplish:
•
Adding a New Switch to an Existing Virtual Chassis Configuration Within the Same
Wiring Closet on page 109
•
Adding a New Switch from a Different Wiring Closet to an Existing Virtual Chassis
Configuration on page 110
•
Adding a New Switch to an Existing Preprovisioned Virtual Chassis Configuration Using
Autoprovisioning on page 112
Adding a New Switch to an Existing Virtual Chassis Configuration Within the Same Wiring Closet
Before you begin, be sure you have:
•
Mounted the new switch in a rack.
•
Confirmed that the new switch is powered off.
•
If you are expanding a preprovisioned configuration, made a note of the serial number
(on the back of the switch). You will need to edit the Virtual Chassis configuration to
include the serial number of the new member switch.
•
If you are expanding a preprovisioned configuration, edited the existing Virtual Chassis
configuration to include the serial number of the new member switch. You can specify
the role of the new member switch when you add its serial number in the Virtual Chassis
configuration file. The parameters specified in the master Virtual Chassis configuration
