5.4.2 GVRP
GVRP (GARP VLAN Registration Protocol) is an implementation of GARP (generic attribute
registration protocol). GVRP allows the switch to automatically add or remove the VLANs via
the dynamic VLAN registration information and propagate the local VLAN registration
information to other switches, without having to individually configure each VLAN.
GVRP has the following three port registration modes: Normal, Fixed, and Forbidden.
Normal: In this mode, a port can dynamically register/deregister a VLAN and propagate
the dynamic/static VLAN information.
Fixed: In this mode, a port cannot register/deregister a VLAN dynamically. It only
propagates static VLAN information. That is, a trunk port only permits the packets of
manually configured VLANs in this mode even if you configure the port to permit the
packets of all the VLANs.
Forbidden: In this mode, a port cannot register/deregister VLANs. It only propagates
VLAN 1 information. That is, a trunk port only permits the packets of the default VLAN
(namely VLAN 1) in this mode even if you configure the port to permit the packets of all
the VLANs.
Configuration Steps
:
Step 1
Select a specific port for setting;
Step 2
Enable or disable the GVRP function on the port;
Step 3
Select the Registration Type for the selected port.
The lower part lists the GVRP attribute of all ports.
Caution:
•
If a port is configured in RecoverRing II™, it cannot be enabled GVRP
;
•
The port to configure GVRP must be a trunk port.
