layer
Ingress: Untagged frames are classified to the VLAN
associated with the port on which the frame is
received. Tagged frames are classified to the VLAN
identified by the VLAN tag in the frame’s tag header.
Note:
For 802.1q mode: if a tagged frame is received,
but the VLAN for that tagged frame does not
exist on the switch, that frame will be placed
onto the port VLAN assigned to the port. This
may cause unicast and broadcast VLAN traffic
from other VLANs to be seen on the port
VLAN. To avoid this behavior, you can set the
port VLAN into the “discard” VLAN which will
drop all untagged frames and tagged frames
with unknown VLAN IDs. For Multi-layer: if a
tagged frame is received, but the VLAN for that
tagged frame does not exists on the switch,
that frame will be dropped. Forwarding:
All broadcast frames from all VLANs will be forwarded
to the port.
Egress: All frames transmitted out of the port to be
tagged using the IEEE 802.1Q/Multi-Layer tag header
format. The tagged used will be that of the VLAN in
which the frame was received.
