Tagged Private VLANs can span switches but trunking ports must be VLAN-trunking ports - see
Advanced > VLAN > VLAN Port Setting.
This is the communication process if primary VLAN P-VLAN 100 is associated with community
VLAN C-VLAN 101 and isolated VLAN I-VLAN 102.
• Promiscuous ports in P-VLAN 100 can communicate with all ports in P-VLAN 100 including
community ports in C-VLAN 101 and isolated ports in I-VLAN 102.
• Community ports in C-VLAN 101 can communicate with promiscuous ports in P-VLAN 100 and
other community ports in C-VLAN 101. They cannot communicate with isolated ports in I-VLAN
102.
• Isolated ports can communicate with promiscuous ports in P-VLAN 100. They cannot
communicate with other isolated ports in I-VLAN 102 nor community ports in C-VLAN 101.
