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… Use the command… Remarks
Enter system view system-view —
Enter VLAN view vlan vlan-id —
Associate an IP subnet with the
current VLAN
ip-subnet-vlan
[ ip-subnet-index ] ip
ip-address [ mask ]
Required
The IP network segment or IP
address to be associated with
a VLAN cannot be a multicast
network segment or a
multicast address.
