802.1Q VLAN diagram
Configuring 802.1Q VLAN Tagging. Before enabling VLANs for the LB52xA-KIT, you
must first assign each port to the VLAN group(s) in which it will participate. By default
all ports are assigned to VLAN1 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 Generic VLAN Routing Protocol
(GVRP). However, if you want a port on this LB52xA-KIT 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 net-
work inter-connection devices, but the VLAN tags should be stripped off before pass-
ing it on to any end-node host that does not support VLAN tagging.
• VLAN Classification - When the LB52xA-KIT receives a frame, it classifies the
frame in one of two ways. If the frame is untagged, the LB52xA-KIT assigns the
frame to an associated VLAN (based on the default VLAN ID of the receiving
port). But if the frame is tagged, the LB52xA-KIT uses the tagged VLAN ID to
identify the port broadcast domain of the frame.
