GVRP
■Send VLAN advertisements, and also receive advertisements for VLANs on other ports and dynamically join those VLANs.
■Send VLAN advertisements, but ignore advertisements received from other ports.
■Avoid GVRP participation by not sending advertisements and dropping any advertisements received from other devices.
IP Addressing. A dynamic VLAN does not have an IP address, and moves traffic on the basis of port membership in VLANs. However, after GVRP creates a dynamic VLAN, you can convert it to a static VLAN. Note that it is then necessary to assign ports to the VLAN in the same way that you would for a static VLAN that you created manually. In the static state you can configure IP addressing on the VLAN and access it in the same way that you would any other static (manually created) VLAN.
An “unknown VLAN” is a VLAN that the switch learns of by receiving an advertisement for that VLAN on a port that is not already a member of that VLAN. If the port is configured to learn unknown VLANs, then the VLAN is dynamically created and the port becomes a tagged member of the VLAN. For example, suppose that in figure
When you enable GVRP on a switch, you have the
