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

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