Private VLAN Groups
The private VLAN group allows you to create groups of users within a VLAN that cannot
communicate with members in different groups but only within the same group. There are two
modes for the private group. The mode can be either isolated or community. When in isolated
mode, the member port in the group cannot forward its egress traffic to any other members in
the same group. the default mode is community, in which each member port can forward
traffic to other members in the same group, but not to members in other groups. The following
examples show how to create a private group.
