If no communication is possible in the VLAN 1 on a certain switch port, go to the menu Configuration → VLAN → Private VLANs → Private VLAN Membership and make sure, that all ports are a member of the Private VLAN 1. When a Private VLAN has been created, a switch port must be a member of the respective VLAN as well as the corresponding Private VLAN for the communication to be possible. In the default configuration all switch ports are a member of the Private VLAN 1. Therefore only the VLAN 1 is affected unless additional Private VLANs are added. |
