Enabling GVRP on a Layer 2 Interface
To enable GVRP on a Layer 2 interface, use the following command.
● Enable GVRP on a Layer 2 interface.
INTERFACE mode
gvrp enable
To inspect the interface configuration, use the show config command from INTERFACE mode or use the show gvrp
interface command in EXEC or EXEC Privilege mode.
Configure GVRP Registration
Configure GVRP registration.
There are two GVRP registration modes:
● Fixed Registration Mode — figuring a port in fixed registration mode allows for manual creation and registration of VLANs,
prevents VLAN deregistration, and registers all VLANs known on other ports on the port. For example, if an interface
is statically configured via the CLI to belong to a VLAN, it should not be unconfigured when it receives a Leave PDU.
Therefore, the registration mode on that interface is FIXED.
● Forbidden Mode — Disables the port to dynamically register VLANs and to propagate VLAN information except information
about VLAN 1. A port with forbidden registration type thus allows only VLAN 1 to pass through even though the PDU carries
information for more VLANs. Therefore, if you do not want the interface to advertise or learn about particular VLANS, set
the interface to the registration mode of FORBIDDEN.
Based on the configuration in the following example, the interface is not removed from VLAN 34 or VLAN 35 despite receiving
a GVRP Leave message. Additionally, the interface is not dynamically added to VLAN 45 or VLAN 46, even if a GVRP Join
message is received.
Example of the gvrp registration Command
Configure a GARP Timer
Set GARP timers to the same values on all devices that are exchanging information using GVRP.
There are three GARP timer settings.
● Join — A GARP device reliably transmits Join messages to other devices by sending each Join message two times. To
define the interval between the two sending operations of each Join message, use this parameter. The Dell EMC Networking
OS default is 200ms.
● Leave — When a GARP device expects to de-register a piece of attribute information, it sends out a Leave message and
starts this timer. If a Join message does not arrive before the timer expires, the information is de-registered. The Leave
timer must be greater than or equal to 3x the Join timer. The Dell EMC Networking OS default is 600ms.
● LeaveAll — After startup, a GARP device globally starts a LeaveAll timer. After expiration of this interval, it sends out a
LeaveAll message so that other GARP devices can re-register all relevant attribute information. The device then restarts the
LeaveAll timer to begin a new cycle. The LeaveAll timer must be greater than or equal to 5x of the Leave timer. The Dell
EMC Networking OS default is 10000ms.
