ip-address – The IP address that defines the subnet. Valid IP
addresses consist of four decimal numbers, 0 to 255, separated by
periods.
mask – This mask identifies the host address bits of the IP subnet.
vlan-id – VLAN to which matching IP subnet traffic is forwarded.

Each IP subnet can be mapped to only one VLAN ID. An IP subnet
consists of an IP address and a subnet mask.
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.

The following example assigns traffic for the subnet 192.168.12.192, mask
255.255.255.224, to VLAN 4.
Console(config)#subnet-vlan subnet 192.168.12.192 255.255.255.224 vlan 4
