In large local area networks (LANs), you commonly need to aggregate traffic from a
number of access switches into a distribution switch.
This example describes how to connect an access switch to a distribution switch:
Requirements on page 1320
Overview and Topology on page 1320
Configuring the Access Switch on page 1322
Configuring the Distribution Switch on page 1326
Verification on page 1328
This example uses the following hardware and software components:
For the distribution switch, one EX4200-24F switch. This model is designed to be used
as a distribution switch for aggregation or collapsed core network topologies and in
space-constrained data centers. It has twenty-four 1-Gigabit Ethernet fiber SFP ports
and an EX-UM-2XFP uplink module with two 10-Gigabit Ethernet XFP ports.
For the access switch, one EX3200-24P, which has twenty-four 1-Gigabit Ethernet
ports, all of which support Power over Ethernet (PoE), and an uplink module with four
1-Gigabit Ethernet ports.
Junos OS Release 9.0 or later for EX Series switches
Before you connect an access switch to a distribution switch, be sure you have:
Installed the two switches. See Installing and Connecting an EX3200 or EX4200 Switch.
Performed the initial software configuration on both switches. See "Connecting and
Configuring an EX Series Switch (J-Web Procedure)" on page 189.
In a large office that is spread across several floors or buildings, or in a data center, you
commonly aggregate traffic from a number of access switches into a distribution switch.
This configuration example shows a simple topology to illustrate how to connect a single
access switch to a distribution switch.
In the topology, the LAN is segmented into two VLANs, one for the sales department and
the second for the support team. One 1-Gigabit Ethernet port on the access switch's
uplink module connects to the distribution switch, to one 1-Gigabit Ethernet port on the
distribution switch.
