GVRP

Introduction

Planning for GVRP Operation

These steps outline the procedure for setting up dynamic VLANs for a seg­ ment.

1.Determine the VLAN topology you want for each segment (broadcast domain) on your network.

2.Determine the VLANs that must be static and the VLANs that can be dynamically propagated.

3.Determine the device or devices on which you must manually create static VLANs in order to propagate VLANs throughout the segment.

4.Determine security boundaries and how the individual ports in the seg­ ment will handle dynamic VLAN advertisements. (See table 3-1on page 3-7and table 3-2on page 3-9.)

5.Enable GVRP on all devices you want to use with dynamic VLANs and configure the appropriate “Unknown VLAN” parameter (Learn, Block, or Disable) for each port.

6.Configure the static VLANs on the switch(es) where they are needed, along with the per-VLAN parameters (Tagged, Untagged, Auto, and Forbid— see table 3-2on page 3-9) on each port.

7.Dynamic VLANs will then appear automatically, according to the config­ uration options you have chosen.

8.Convert dynamic VLANs to static VLANs where you want dynamic VLANs to become permanent.

Configuring GVRP On a Switch

The procedures in this section describe how to:

View the GVRP configuration on a switch

Enable and disable GVRP on a switch

Specify how individual ports will handle advertisements

To view or configure static VLANs for GVRP operation, refer to “Per-Port Static VLAN Configuration Options” on page 2-9.
