GVRP
Introduction
| As the preceding table indicates, when you enable GVRP, a port that has a |
| Tagged or Untagged static VLAN has the option for both generating advertise |
| ments and dynamically joining other VLANs. |

| configured per static VLAN on every port, using either the menu interface or |
| the CLI. |
| Because dynamic VLANs operate as Tagged VLANs, and because a tagged port |
| on one device cannot communicate with an untagged port on another device, |
| ProCurve recommends that you use Tagged VLANs for the static VLANs you |
| will use to generate advertisements. |

GVRP and VLAN Access Control
When you enable GVRP on a switch, the default GVRP parameter settings allow all of the switch’s ports to transmit and receive dynamic VLAN adver tisements (GVRP advertisements) and to dynamically join VLANs. The two preceding sections describe the
■ Allow a port to advertise and/or join dynamic VLANs (Learn
■ Allow a port to send VLAN advertisements, but not receive them from other devices; that is, the port cannot dynamically join a VLAN but other devices can dynamically join the VLANs it advertises (Block mode).
■ Prevent a port from participating in GVRP operation (Disable mode).
A dynamic VLAN continues to exist on a port for as long as the port continues to receive advertisements of that VLAN from another device connected to that port or until you:
■ Convert the VLAN to a static VLAN (See “Converting a Dynamic VLAN to a Static VLAN” on page
■ Reconfigure the port to Block or Disable ■ Disable GVRP
■ Reboot the switch
