IP Subnet-Based VLAN Configuration
Introduction
In this approach, packets are assigned to VLANs based on their source IP addresses and subnet
masks. A port configured with IP subnet-based VLANs assigns a received untagged packet to a VLAN
based on the source address of the packet.
This feature is used to assign packets from the specified network segment or IP address to a specific
VLAN.
Configuring an IP Subnet-Based VLAN
This feature is only applicable on hybrid ports.
Follow these steps to configure an IP subnet-based VLAN:
