Subnet based VLANs allow users to group traffic into logical VLANs based on the 

source IP address and IP subnet. When a frame is received on a port, the switch 

checks where the IP subnet it came from and what the source IP address is. The 

untagged packets from the same IP subnet are then placed in the same subnet 

based VLAN. The most significant advantage of using subnet based VLANs is that 

the priority can be divided and tuned base on what VLAN the traffic belongs to. 

Considering the following topology:   

Purpose:  

Traffic from VoIP phone (source IP: 192.168.1.10) will be categorized into VLAN 3. 

Traffic from IPTV (source IP: 192.168.5.10) will be categorized into VLAN 4. 

Traffic from the PC (source IP: 192.168.10.10) will be categorized into VLAN 5.
