6.8 Private VLAN
Private VLANs, designed to save VLAN resources of uplink devices and decrease broadcast,
are sets of VLAN pairs that share a common primary identifier. To guarantee user information
security, the ease with which to manage and account traffic for service providers, in campus
network, service providers usually require that each individual user is layer-2 separated. VLAN
feature can solve this problem. However, as stipulated by IEEE 802.1Q protocol, a device can
only support up to 4094 VLANs. If a service provider assigns one VLAN per user, the VLANs will
be far from enough; as a result, the number of users this service provider can support is limited.
