Example
This shows that traffic entering Port 1 that matches the specifications for protocol
group 1 will be mapped to VLAN 2:

Configuring IP Subnet VLANs
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.

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)
