When using IEEE 802.1Q port-based VLAN 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).
subnet-vlan
This command configures IP Subnet VLAN assignments. Use the no form to
remove an IP subnet-to-VLAN assignment.

subnet-vlan subnet ip-address mask vlan vlan-id [ priority priority ]
no subnet-vlan subnet { ip-address mask | all }
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.
(Range: 1-4093)
priority – The priority assigned to untagged ingress traffic.
(Range: 0-7, where 7 is the highest priority)

◆
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
