its own VLAN. Additionally, protocol-based classification allows an
administrator to assign nonroutable protocols, such as NetBIOS or DECnet,
to larger VLANs than routable protocols like IPX or IP. This maximizes the
efficiency gains that are possible with VLANs.
In port-based VLAN classification, the Port VLAN Identifier (PVID) is
associated with the physical ports. The VLAN ID (VID) for an untagged
packet is equal to the PVID of the port. In port-and protocol-based VLAN
classifications, multiple VIDs are associated with each of the physical ports.
Each VID is also associated with a protocol. The ingress rules used to classify
incoming packets include the use of the packet's protocol, in addition to the
PVID, to determine the VLAN to which the packet belongs. This approach
requires one VID on each port for each protocol for which the filter is desired.

IP Subnet Based VLANs

This feature allows an untagged packet to be placed in a configured VLAN
based upon its IP address.

MAC-Based VLANs

This feature allows an untagged packet to be placed in a configured VLAN
based upon its MAC address.
