supported.

This example requires one EX Series switch with Junos OS Release 9.3 or later for EX
Series switches.
Before you begin configuring a private VLAN, make sure you have created and configured
the necessary VLAN. See "Configuring VLANs for EX Series Switches (CLI Procedure)"
on page 1378 or "Configuring VLANs for EX Series Switches (J-Web Procedure)" on page 1375.
In a large office with multiple buildings and VLANs, you might need to isolate some
workgroups or other endpoints for security reasons or to partition the broadcast domain.
This configuration example shows a simple topology to illustrate how to create a private
VLAN with one primary VLAN and two community VLANs, one for HR and one for finance,
as well as two isolated ports for the mail server and the backup server.
Table 192 on page 1350 lists the settings for the example topology.
