Chapter 4. EX Virtual Chassis

EX4200 switches support clustering of up to ten 4200 chassis into a single Virtual Chassis (VC), which provides significant High Availability (HA) benefits in addition to simplified network management. VC capabilities are included in the base 4200 model. A VC can be built incrementally, which means you can grow the VC by adding one or more switch chassis at any time, until the 10-chassis limit is reached, and you can mix and match any EX4200 model as part of the same VC. This capability means an enterprise can start at a modest scale with a single 4200 chassis, and then expand into a full-blown VC offering a local switching capacity of 1.36 Tbps/1.01 Bpps, with 128 Gbps of throughput for switching within the VC.

The topics covered in this chapter include:

  • EX VC operation and deployment designs

  • Configuration, operation, and maintenance

  • VC deployment case study

The EX Virtual Chassis

The EX4200 VC is an exciting concept. By simply attaching a few rear-panel cables, you can turn any mix of 10 standalone 4200s into a single logical entity that both simplifies management and increases resiliency to hardware- and software-related faults.

Virtual Chassis Overview

The individual member switches comprising a VC can be any type of EX4200, with any mix of supported power supply units (PSUs), Power over Ethernet (PoE) options, and uplink modules. A fully blown VC can offer 480×1 GE and 20×10 GE ports with 128 Gbps of full duplex (FD) switching capacity between any pair ...
