Private VLAN
This chapter shows you how to configure the Switch to prevent communications between
ports in a VLAN.
32.1 Private VLAN Overview
Private VLAN allows you to do port isolation within a VLAN in a simple way. You specify which port(s) in a
VLAN is not isolated by adding it to the promiscuous port list. The Switch automatically adds other ports
in this VLAN to the isolated port list and blocks traffic between the isolated ports. A promiscuous port can
communicate with any port in the same VLAN. An isolated port can communicate with the promiscuous
port(s) only.
Note: You can have up to one private VLAN rule for each VLAN.
Figure 207 Private VLAN Example
Note: Make sure you keep at least one port in the promiscuous port list for a VLAN with private
VLAN enabled. Otherwise, this VLAN is blocked from the whole network.
