Configuring Private VLANs
Private VLANs provide port-based security and isolation between ports within the
assigned VLAN. This switch supports two types of private VLAN ports: promiscuous,
and community ports. A promiscuous port can communicate with all interfaces within
a private VLAN. Community ports can only communicate with other ports in their
own community VLAN, and with their designated promiscuous ports. This section
describes commands used to configure private VLANs.
To configure private VLANs, follow these steps:
1. Use the private-vlan command to designate one or more community VLANs
and the primary VLAN that will channel traffic outside the community groups.
2. Use the private-vlan association command to map the secondary (i.e.,
community) VLAN(s) to the primary VLAN.
3. Use the switchport mode private-vlan command to configure ports as
promiscuous (i.e., having access to all ports in the primary VLAN) or host (i.e.,
having access restricted to community VLAN members, and channeling all
other traffic through a promiscuous port).
4. Use the switchport private-vlan host-association command to assign a port
to a secondary VLAN.
5. Use the switchport private-vlan mapping command to assign a port to a
primary VLAN.
6. Use the show vlan private-vlan command to verify your configuration settings.
