NETGEAR Managed Switches Software Administration Manual, Release 8.0 Virtual VLANs: Create an IP Subnet Based VLAN In an IP subnet based VLAN, all the end workstations in an IP subnet are classified to the same VLAN. In this VLAN, users can move their workstations without reconfiguring their network addresses. IP subnet VLANs are based on layer 3 information from packet headers. The switch makes use of the network-layer address (for example, subnet address for TCP/IP networks) in determining VLAN membership. If a packet is untagged or priority-tagged, the switch will associate the packet with any matching IP subnetclassification. If no IP subnet classification can be made, the packet is subjected to the normal VLAN classification rules of the switch. This IP subnet capability does not imply a routing function or that the VLAN is routed. The IP subnet classification feature only affects the VLAN assignment of a packet. Appropriate 802.1Q VLAN configuration must exist in order for the packet to be switched. 1/0/1 Switch 1/0/24 PC 1 10.100.5.1 Figure 3-19 CLI: Creating an IP Subnet Based VLAN PC 2 10.100.5.30 (Netgear Switch) #vlan database (Netgear Switch) (Vlan)#vlan 2000 (Netgear Switch) (Vlan)#vlan association subnet 10.100.0.0 255.255.0.0 2000 (Netgear Switch) (Vlan)#exit Virtual LANs v1.0, October 2009 3-16
