7.12.5 IP Subnet-based VLAN
In an IP subnet-based VLAN, all the end workstations in an IP subnet are
assigned 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, the subnet address for TCP/IP networks) in
determining VLAN membership. If a packet is untagged or priority tagged, the
switch associates the packet with any matching IP subnet classification. 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 affects only the VLAN assignment of
a packet. Appropriate 802.1Q VLAN configuration must exist in order for the
packet to be switched.
