4.3.1.1.2 802.1Q VLAN
Tagged-based VLAN is an IEEE 802.1Q specification standard. Therefore, it is possible to create a VLAN across
devices from different switch venders. IEEE 802.1Q VLAN uses a technique to insert a "tag" into the Ethernet frames.
Tag contains a VLAN Identifier (VID) that indicates the VLAN numbers.
You can create and delete Tag-based VLAN. There are 26 VLAN groups to provide configure. Enable 802.1Q VLAN, the
all ports on the switch belong to default VLAN, VID is 1. The default VLAN can't be deleting.
„ Understand nomenclature of the Switch
Tagging and Untagging
Every port on an 802.1Q compliant switch can be configured as tagging or untagging.
。 Tagging: Ports with tagging enabled will put the VID number, priority and other VLAN information into the header
of all packets that flow into those ports. If a packet has previously been tagged, the port will not alter the packet,
thus keeping the VLAN information intact. The VLAN information in the tag can then be used by other 802.1Q
