4.5.9 Subnet VLAN Setting

Overview
This feature enables network manager to limit the amount of broadcast traffic end-stations, servers, and routers need to accept.
Ethernet virtualization is often deployed in Layer 2 switches, and has steadily gained popularity in supporting network and
security services virtualization in network appliances. Virtualization may thus rely on VLANs to distinguish traffic to specific
service instances. In such cases, VLAN switching needs to be performed with IP address intelligence, since an IP packet
entering the premises from outside may not have a VLAN ID already associated.
The above task of VLAN switching based on IP addresses (IP-based VLAN switching or Subnet VLAN switching) may be
implemented as a software module integrated within a target appliance that provides the services, or within a separate switching
device external to the target appliance.
