Use the VLAN > IP Subnet page to configure IP subnet-based VLANs.
When using port-based classification, all untagged frames received by a
port are classified as belonging to the VLAN whose VID (PVID) is
associated with that port.
When IP subnet-based VLAN classification is enabled, the source address of
untagged ingress frames are checked against the IP subnet-to-VLAN
mapping table. If an entry is found for that subnet, these frames are
assigned to the VLAN indicated in the entry. If no IP subnet is matched, the
untagged frames are classified as belonging to the receiving port’s VLAN ID
(PVID).

◆
Each IP subnet can be mapped to only one VLAN ID. An IP subnet
consists of an IP address and a mask. The specified VLAN need not be
an existing VLAN.
◆
When an untagged frame is received by a port, the source IP address is
checked against the IP subnet-to-VLAN mapping table, and if an entry
is found, the corresponding VLAN ID is assigned to the frame. If no
mapping is found, the PVID of the receiving port is assigned to the
frame.
◆
The IP subnet cannot be a broadcast or multicast IP address.
◆
When MAC-based, IP subnet-based, and protocol-based VLANs are
supported concurrently, priority is applied in this sequence, and then
port-based VLANs last.
P
ARAMETERS
These parameters are displayed:
◆
IP Address – The IP address for a subnet. Valid IP addresses consist of
four decimal numbers, 0 to 255, separated by periods.
◆
Subnet Mask – This mask identifies the host address bits of the IP
subnet.
◆
VLAN – VLAN to which matching IP subnet traffic is forwarded.
(Range: 1-4094)
◆
Priority – The priority assigned to untagged ingress traffic.
(Range: 0-7, where 7 is the highest priority; Default: 0)
