4.2.2-4-7. VLAN configuration
A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain. It allows you to isolate network traffic
so only members of the VLAN receive traffic from the same VLAN members. Basically, creating a VLAN from a NVF-800S is
logically equivalent of reconnecting a group of network devices to another Layer 2 NVF-800S. However, all the network
devices are still plug into the same NVF-800S physically.
The IP DSLAM supports port-based and protocol-base VLAN in web management page, In the default configuration, VLAN
support is enable and all ports on the NVF-800S belong to default VLAN, VID is 1.
Support Multiple VLAN (IEEE 802.1Q VLAN)
Port-based Tagging rule VLAN is an IEEE 802.1Q specification standard. Therefore, it is possible to create a VLAN across
devices from different NVF-800S venders. IEEE 802.1Q VLAN uses a technique to insert a “tag” into the Ethernet frames.
Tag contains a VLAN Identifier (VID) that indicates the VLAN numbers.
