To configure primary/secondary associated groups, 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 of 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 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.
