Port-Based Virtual LANs (VLANs) and GVRP

GVRP

Per-Port Options for Dynamic VLAN Advertising and Joining

Initiating Advertisements. As described in the preceding section, to enable dynamic joins, GVRP must be enabled and a port must be configured to Learn (the default). However, to send advertisements in your network, one or more static (Tagged, Untagged, or Auto) VLANs must be configured on one or more switches (with GVRP enabled), depending on your topology.

Enabling a Port for Dynamic Joins. You can configure a port to dynami­ cally join a static VLAN. The join will then occur if that port subsequently receives an advertisement for the static VLAN. (This is done by using the Auto and Learn options described in table 11-4,below.

Parameters for Controlling VLAN Propagation Behavior. You can configure an individual port to actively or passively participate in dynamic VLAN propagation or to ignore dynamic VLAN (GVRP) operation. These options are controlled by the GVRP “Unknown VLAN” and the static VLAN configuration parameters, as described in the following table:
