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 Tagged or Untagged static VLANs must be configured on one or more switches (with GVRP enabled), depending on your topology.

Enabling a Static VLAN for Dynamic Joins. You can configure a port to dynamically join a static VLAN (that shares the same VID) if that port subse- quently receives an advertisement for the static VLAN. (This is done by using the Auto and Learn options described in table 9-9, below.

Parameters for Controlling VLAN Propagation Behavior. On an indi- vidual port, you can configure an existing static VLAN 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:

1Each port of a Series 2500 switch must be a Tagged or Untagged member of at least one VLAN. Thus, any port configured for GVRP to Learn or Block will generate and forward advertisements for the static VLAN(s) for which it has been configured as Tagged or Untagged . By default, all ports are Untagged members of the default VLAN (VID = 1). See the “Note” on page page 9-78.

2To configure tagging, Auto, or Forbid, see “Configuring Static VLAN Name and Per-Port Settings” on page 9-67 (for the CLI) or “Adding or Changing a VLAN Port Assignment” on page 9-60 (for the menu).
