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 2-27(for the CLI) or “Adding or Changing a VLAN Port Assignment” on page 2-18(for the menu).

 

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.

 

 

N o t e

In table 3-2,above, the Unknown VLAN parameters are configured on a per-

 

port basis using the CLI. The Tagged, Untagged, Auto, and Forbid options are

 

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.
