4.22 Subnet Based VLANs
Subnet based VLANs allow you to group traffic into logical VLANs based on the source IP subnet you
specify. When a frame is received on a port, the MSC checks if a tag is added already and the IP
subnet it came from. The untagged packets from the same IP subnet are then placed in the same
subnet based VLAN. One advantage of using subnet based VLANs is that priority can be assigned to
traffic from the same IP subnet.
For example, an ISP (Internet Services Provider) may divide different types of services it provides
to customers into different IP subnets. Traffic for voice services is designated for IP subnet
172.16.1.0/24, video for 192.168.1.0/24 and data for 10.1.1.0/24. The MSC can then be
configured to group incoming traffic based on the source IP subnet of incoming frames.
