NOTE: When an uplink port is set as a VCP interface, it cannot be used for
any other purpose. You can set one port as a VCP interface and configure the
other port in trunk mode as an uplink to a distribution switch.
Before you set an uplink port as a VCP:
Install the uplink module in the member switches that you want to interconnect.
1.
Power on and connect to the switch that you plan to designate as the master of the
2.
Virtual Chassis configuration.
NOTE: Do not power on the other switches at this point.
Run EZSetup on the switch that you are configuring to be the master. Follow the
3.
prompts to specify the hostname and other identification, time zone, and network
properties. See "Connecting and Configuring an EX Series Switch (CLI Procedure)"
on page 199 or "Connecting and Configuring an EX Series Switch (J-Web Procedure)"
on page 201 for details. The properties that you specify for the master apply to the
entire Virtual Chassis configuration, including all the member switches that you later
interconnect with the master.
If you want to configure and manage the Virtual Chassis configuration remotely, specify
4.
the VME global management interface. You can configure the VME global management
interface when you are setting up the master or you can do it after completing the
other configuration steps for the Virtual Chassis. See "Configuring the Virtual
Management Ethernet Interface for Global Management of an EX4200 Virtual Chassis
(CLI Procedure)" on page 999.
Configure mastership of the Virtual Chassis using either the nonprovisioned or
5.
preprovisioned configuration. See "Configuring Mastership of the EX4200 Virtual
Chassis (CLI Procedure)" on page 992 for details.
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 configuration. This ensures
that the configuration changes are saved in both Routing Engines.
To interconnect a Virtual Chassis configuration across longer distances, such as wiring
closets, you need to:
Prepare the existing Virtual Chassis configuration for interconnecting with a potential
member switch that is beyond the reach of a Virtual Chassis cable by setting at least
one uplink VCP on an existing member of the Virtual Chassis configuration.
Prepare the potential member switch for interconnecting with the existing Virtual
Chassis configuration by setting at least one uplink VCP on the standalone switch.
