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 Tag-based VLAN, and enable or disable GVRP protocol. There
are 256 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.
GVRP allows automatic VLAN configuration between the switch and nodes. If
the switch is connected to a device with GVRP enabled, you can send a GVRP
request using the VID of a VLAN defined on the switch; the switch will
automatically add that device to the existing VLAN.
802.1Q Configuration
You can select to be in use or don't be in use GVRP makes an agreement.
GVRP is In use :
When you are in use GVRP function, this chance automatically joins the
VLANs set that the upper level switch add into this machine VLANs set and
reminds you: When you are in use this function you have to open the GVRP
function of upper level switch, otherwise, this function will can't function.
