Assigning Ports to VLANs

Before enabling VLANs for the switch, you must first assign each port to the VLAN group(s) in which it will participate. By default

all ports are assigned to VLAN 1 as untagged ports. Add a port as a tagged port if you want it to carry traffic for one or more

VLANs, and any intermediate network devices or the host at the other end of the connection supports VLANs. Then assign

network devices along the path that will carry this traffic to the same VLAN(s), either manually or

dynamically using GVRP. However, if you want a port on this switch to participate in one or more VLANs, but none of the

e user

When the switch receives a frame, it classifies the frame in one of two ways. If the frame is untagged, the switch assigns th

frame to an associated VLAN (based on the default VLAN ID of the receiving port). But if the frame is tagged, the switch uses

the tagged VLAN ID to identify the port broadcast domain o

■

Port Overlapping

Port overlapping can be used to allow access to commonly shared network resources among different VLAN groups, such as

file servers or printers. Note that if you implement VLANs which do not overlap, but still need to communicate, you can

them by enabled routing on this switch.

Untagged (or static) VLANs are typically used to reduce broadcast traffic and to increase security. A group of network users

assigned to a VLAN form a broadcast domain that is separate from other VLANs configured on the switch. Packets are

forwarded only between ports that are designated for the same VLAN. Untagged VLANs can be used to manually isolat

groups or subnets.
