By default, the GVRP registration type is normal.
Displaying and Debugging GVRP
After you set the GVRP registration type, execute the display command in all
views to display the GVRP configuration and to verify the effect of the
configuration.
Execute the debugging command in user view to debug the configuration of
GVRP.
