4.3.3.6 Port Isolation
Overview
When a VLAN is configured to be a private VLAN, communication between ports within that VLAN can be prevented. Two
application examples are provided in this section:
Customers connected to an ISP can be members of the same VLAN, but they are not allowed to communicate with each
other within that VLAN.
Servers in a farm of web servers in a Demilitarized Zone (DMZ) are allowed to communicate with the outside world and
with database servers on the inside segment, but are not allowed to communicate with each other
A row of check boxes for each port is displayed for each private VLAN ID. To
include a port in a Private VLAN, check the box. To remove or exclude the port
from the Private VLAN, make sure the box is unchecked. By default, no ports are
members, and all boxes are unchecked.
Click "Add New Private VLAN" to add a new private VLAN ID. An empty row is
added to the table, and the private VLAN can be configured as needed. The
allowed range for a private VLAN ID is the same as the switch port number
range. Any values outside this range are not accepted, and a warning message
appears. Click "OK" to discard the incorrect entry, or click "Cancel" to return to
the editing and make a correction.
The Private VLAN is enabled when you click "Save".
The "Delete" button can be used to undo the addition of new Private VLANs.
: Click to add new VLAN.
