Figure 47: Static VLAN interface
NOTE:
1. No matter what basis is used to uniquely identify end nodes and assign these
nodes VLAN membership, packets cannot cross VLAN without a network device
performing a routing function between the VLAN.
2. The Switch supports Port-based VLAN and IEEE 802.1Q VLAN. The port untagging
function can be used to remove the 802.1 tag from packet headers to maintain
compatibility with devices that are tag-unaware.
Port-Based VLAN
Packets can go among only members of the same VLAN group. Note all unselected
ports are treated as belonging to another single VLAN. If the port-based VLAN
enabled, the VLAN-tagging is ignored.
In order for an end station to send packets to different VLANs, it itself has to be either
capable of tagging packets it sends with VLAN tags or attached to a VLAN-aware
bridge that is capable of classifying and tagging the packet with different VLAN ID
based on not only default PVID but also other information about the packet, such as
the protocol.
