4.2.2.4.7 VLAN Configuration
A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain. It allows one to isolate network traffic
so only members of the VLAN can receive traffic from the same VLAN members. Basically, creating a VLAN from a
NVF-800S is a 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 NVF-800S supports port-based and protocol-based VLAN in web management. In the default configuration, VLAN is
enabled 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 vendors. 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.
