VLAN Commands

subnet-vlan
This command configures IP Subnet VLAN assignments. Use the no form to remove
an IP subnet-to-VLAN assignment.
Syntax
subnet-vlan subnet ip-address mask vlan vlan-id
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: 1-4094)
Default Setting
None
Command Mode
Global Configuration
Command Usage
• 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.
Example
The following example assigns traffic for the subnet 192.168.12.192, mask
255.255.255.224, to VLAN 4.
show subnet-vlan
This command displays IP Subnet VLAN assignments.
Command Mode
Privileged Exec
Command Usage
• Use this command to display subnet-to-VLAN mappings.
• The last matched entry is used if more than one entry can be matched.
Console(config)#subnet-vlan subnet 192.168.12.192 255.255.255.224 vlan 4
