172.16.1.0/24, video for 192.168.1.0/24 and data for 10.1.1.0/24. The Switch can then be
configured to group incoming traffic based on the source IP subnet of incoming frames.
You can then configure a subnet based VLAN with priority 6 and VID of 100 for traffic received from
IP subnet 172.16.1.0/24 (voice services). You can also have a subnet based VLAN with priority 5
and VID of 200 for traffic received from IP subnet 192.168.1.0/24 (video services). Lastly, you can
configure VLAN with priority 3 and VID of 300 for traffic received from IP subnet 10.1.1.0/24 (data
services). All untagged incoming frames will be classified based on their source IP subnet and
prioritized accordingly. That is, video services receive the highest priority and data the lowest.
