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 ports on the other
VLAN-aware 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 intermediate network devices
nor the host at the other end of the connection supports VLANs,
then you should add this port to the VLAN as an untagged port.
Note: VLAN-tagged frames can pass through VLAN-aware or
VLAN-unaware network interconnection devices, but the
VLAN tags should be stripped off before passing it on to
any end-node host that does not support VLAN tagging.
VLAN Classification – When the switch receives a frame, it
classifies the frame in one of two ways. If the frame is untagged,
the switch assigns the frame to an associated VLAN (based on the
PVID of the receiving port. But if the frame is tagged, the switch
uses the tagged VLAN ID to identify the port broadcast domain of
the frame.
