Configuration Guidelines
The following guidelines apply when configuring Private VLANs:
The default VLAN 1 cannot be a Private VLAN.
The management VLAN 4095 cannot be a Private VLAN. The management port cannot be a
member of a Private VLAN.
IGMP Snooping must be disabled on isolated VLANs.
Each secondary port’s (isolated port and community ports) PVID must match its corresponding
secondary VLAN ID.
Ports within a secondary VLAN cannot be members of other VLANs.
All VLANs that comprise the Private VLAN must belong to the same Spanning Tree Group.

1. Select a VLAN and define the Private VLAN type as primary.
2. Configure a secondary VLAN and map it to the primary VLAN.
