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 .
Note: Isolation in SWITCHING > VLAN > VLAN Setup > VLAN Port Setup has a higher priority than
private VLAN settings, so promiscuous ports with Isolation in SWITCHING > VLAN > VLAN
Setup > VLAN Port Setup enabled will not be able to communicate with each other.
