6.5.3 Advanced 802.1Q VLAN Configuration
Ingress filters configuration
When a packet was received on a port, you can govern the switch to drop it or not if it is an untagged packet. Furthermore, if the
received packet is tagged but not belonging to the same VALN group of the receiving port, you can also control the switch to
forward or drop the packet. The example below configures the switch to drop the packets not belonging to the same VLAN
group and forward the packets not containing VLAN tags.
