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:
To do...
Enter system view
Enter VLAN view
Associate an IP subnet with the
current VLAN
Return to system view
Enter interface
view or port
group view
Configure port link type as hybrid
Configure the hybrid port(s) to
permit the specified IP
subnet-based VLANs to pass
through

In Ethernet interface view,
the subsequent
configurations apply to the
current port.
In port group view, the
subsequent configurations
apply to all ports in the port
group.
In Layer-2 aggregate
interface view,
subsequent configurations
apply to the Layer-2
