To configure private VLANs, follow these steps:
1. Use the private-vlan command to designate one or more isolated or
community VLANs and the primary VLAN that will channel traffic
outside the community groups.
2. Use the private-vlan association command to map the 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., community or isolated port).
4. Use the switchport private-vlan host-association command to
assign a port to a community VLAN. Or use the switchport
private-vlan isolated command to assign a port to an isolated
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.
