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

Required
The IP network segment or IP address to
be associated with a VLAN cannot be a
multicast network segment or a multicast
address.

Required
Use either command.
In Ethernet interface
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,
the subsequent configurations apply
to the Layer-2 aggregate interface and
all its member ports.
