Troubleshooting: No communication within a VLAN on a specific switch port
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.
Therefore go to the menu VLAN Management → Private VLAN and make sure, that all ports are a member of the respective VLAN.

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. |
