    Understanding EX2200 Virtual Chassis Hardware Configuration

    Virtual Chassis is a feature in Juniper Networks EX2200 Ethernet Switches that allows you to interconnect two or more EX2200 switches, enabling them to operate as a unified, single, high bandwidth switch. Starting in Junos OS Release 12.2, you can interconnect a maximum of four EX2200 switches by using the uplink ports configured as Virtual Chassis ports (VCPs) to form a Virtual Chassis.

    Note: EX2200 switches do not have dedicated VCPs.

    All EX2200 switch models, including EX2200-C switches, support Virtual Chassis, and you can interconnect different models, which allows you to choose among a range of possible port configurations within the same Virtual Chassis.

    Note: EX2200-C switches can be interconnected with other EX2200 switches in the same Virtual Chassis.

    The Virtual Chassis configuration includes a master switch and a backup switch, with all other switches in the configuration designated as “linecard” member switches. Virtual Chassis operation is managed through the master switch. Each switch in the Virtual Chassis is assigned a unique member ID.

    Note: Starting with Junos OS Release 12.2R1, PoE commands are enabled on all non-PoE-capable EX2200 switch models. Also the PoE commands do not provide any meaningful information on standalone non-PoE-capable switch models. However, in an EX2200 Virtual Chassis, you can execute PoE commands from a non-PoE-capable switch that is the master, to configure PoE on PoE-capable Virtual Chassis members.
