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
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

frames from all VLANs will be forwarded to the port.
