Configuring IP Subnet VLANs

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

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)

Global Configuration

Each IP subnet can be mapped to only one VLAN ID. An IP subnet

consists of an IP address and a subnet 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

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

Console(config)#
