This example uses the following hardware and software components:
Junos OS Release 9.0 or later for EX Series switches
Two EX4200-48P switches
Four EX4200-24P switches
A Virtual Chassis configuration is easily expandable. This example shows a Virtual Chassis
configuration composed of six EX4200 switches. It provides networking access for 180
onsite workers, who are sitting within range of a single wiring closet. The six combined
switches are identified by a single host name and managed through a global management
IP address.
To set up a multimember Virtual Chassis configuration within a single wiring closet, you
need to run the EZSetup program only once. Connect to the master and run EZSetup to
specify its identification, time zone, and network properties. When additional switches
are connected through the Virtual Chassis ports (VCPs), they automatically receive the
same properties that were specified for the master.
The topology for this example (see Figure 18 on page 929) consists of six switches:
Two EX4200-48P switches (SWA-0 and SWA-1) with 48 access ports, all of which
support Power over Ethernet (PoE)
Four EX4200-24P switches (SWA-2, SWA-3, SWA-4, and SWA-5) with 24 access
ports, all of which support PoE
Figure 18 on page 929 shows that all the member switches are interconnected with the
dedicated VCPs on the rear panel. The LCD on the front displays the member ID and role.
