8.4 Port-based VLAN Setup
Port-based VLANs are VLANs where the packet forwarding decision is based on the
destination MAC address and its associated port.
Port-based VLANs require allowed outgoing ports to be defined for each port. Therefore, if
you wish to allow two subscriber ports to talk to each other, for example, between conference
rooms in a hotel, you must define the egress (an egress port is an outgoing port, that is, a port
through which a data packet leaves) for both ports.
Port-based VLANs are specific only to the ONU on which they were created.
"
When you activate port-based VLAN, the ONU uses a default VLAN ID of 1.
You cannot change it.
"
In screens (such as IP Setup and Filtering ) that require a VID, you must enter
1 as the VID.
The port-based VLAN setup screen is shown next. The CPU management port forms a VLAN
with all Ethernet ports.
