1.6 Configuring IP-Subnet-Based VLAN
1.6.1 Introduction
In this approach, VLANs are categorized based on the source IP addresses and the
subnet masks of packets. After receiving an untagged packet from a port, the device
finds its association with the current VLAN based on the source address contained in
the packet, and then forwards the packet in the corresponding VLAN. This allows
packets from a certain network segment or with certain IP addresses to be forwarded in
a VLAN.
1.6.2 Configuring an IP-Subnet-Based VLAN
 Note:
This feature is only applicable to hybrid ports.
Follow these steps to configure an IP-subnet-based VLAN:
