802.1Q

Each VLAN in a network has an associated VLAN ID, which appears in the IEEE 802.1Q tag in the Layer 2 header of packets transmitted on a VLAN. The IEEE802.1Q specification establishes a standard method for tagging Ethernet frames with VLAN membership information. The key for IEEE802.1Q to perform its functions is in its tags. 802.1Q-compliant Switch ports can be configured to transmit tagged or untagged frames. A tag field containing VLAN information can be inserted into an Ethernet frame. When using an 802.1Q VLAN configuration, ports are then configured to be a part of a VLAN group. When a port receives data tagged for a VLAN group, the data is discarded unless the port is a member of the VLAN group.

VLAN ID	Displays the VLAN ID for which the network policy is defined. The range of the VLAN ID is from 2-4094. VLAN 1 is created by default.
Name	Enter the VLAN name, using up to 32 alphanumeric characters.
Tagged Port	Frames transmitted from this port are tagged with the VLAN ID.
Untagged Port	Frames transmitted from this port are untagged.

Port-based VLAN and 802.1Q VLAN are mutually exclusive. If port-based VLANs are enabled, then 802.1Q VLAN is disabled.
