Private VLAN Commands

This chapter explains how to use commands to configure private VLANs on the Switch.
57.1 Private VLAN Overview
Private VLAN allows you to do port isolation within a VLAN in a simple way. In private
VLAN, a promiscuous port can communicate with any port in the same VLAN. While an
isolated port can communicate with the promiscuous port(s) only.

If you change the VLAN settings, 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.
