1Each port on the 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 static VLAN(s) configured on the switch and also for dynamic VLANs the switch learns on other ports.

2To configure tagging, Auto, or Forbid, see “Configuring Static VLAN Name and Per-Port Settings” on page 2-28(for the CLI) or “Adding or Changing a VLAN Port Assignment” on page 2-19(for the menu).
