Configuring IP subnet-based VLANs

In this method, 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.

Use this feature when packets from an IP subnet or IP address must be transmitted in a VLAN.

This feature is available only on hybrid ports, and it processes only untagged packets.

An IP subnet-based VLAN has one or multiple subnets to match inbound packets. Each subnet has a unique index in the IP subnet-based VLAN. All subnets in an IP subnet-based VLAN have the same VLAN ID.

To configure a IP subnet-based VLAN:

Task	Command	Remarks
1. Enter system view.	system-view	N/A
2. Enter VLAN view.	vlan vlan-id	N/A
3. Associate an IP subnet or IP address with the VLAN.	ip-subnet-vlan [ ip-subnet-index ] ip ip-address [ mask ]	By default, a VLAN is not associated with any IP subnets or IP addresses. A multicast subnet or a multicast address cannot be associated with a VLAN.
4. Return to system view.	quit	N/A
5. Enter interface view.	Enter Layer 2 Ethernet interface view:interface interface-type interface-number Enter Layer 2 aggregate interface view:interface bridge-aggregation interface-number	The configurations made in Layer 2 Ethernet interface view apply only to the port. The configurations made in Layer 2 aggregate interface view apply to the aggregate interface and its aggregation member ports. If the system fails to apply the configurations to the aggregate interface, it stops applying the configurations to the aggregation member ports. If the system fails to apply the configurations to an aggregation member port, it skips the port and moves to the next member port.
6. Configure the port link type as hybrid.	port link-type hybrid	By default, all ports are access ports.
7. Assign the hybrid port to the specified IP subnet-based VLANs.	port hybrid vlan vlan-id-list { tagged \| untagged }	By default, a hybrid port is an untagged member of the VLAN to which the port belongs when its link type is access.
8. Associate the hybrid port with the specified IP subnet-based VLAN.	port hybrid ip-subnet-vlan vlan vlan-id	By default, no IP subnet-based VLAN is associated with a hybrid port.
