Private VLANs
A private VLAN contains switch ports that cannot communicate with each other, but can
access another network. These ports are called private ports. Each private VLAN contains
one or more private ports and a single uplink port or uplink aggregation group. Note
that all traffic between private ports is blocked at all layers, not just Layer 2 traffic, but
also traffic such as FTP, HTTP, and Telnet.
A private VLAN separates a regular VLAN domain into two or more subdomains. Each
subdomain is defined (represented) by a primary VLAN and a secondary VLAN:
