GVRP
Table 148 lists the individual Brocade FastIron switches and the GARP VLAN Registration Protocol
(GVRP) features they support. These features are supported in the Layer 2, base Layer 3, edge
Layer 3, and full Layer 3 software images, except where explicitly noted.
GVRP overview
GARP VLAN Registration Protocol (GVRP) is a Generic Attribute Registration Protocol (GARP)
application that provides VLAN registration service by means of dynamic configuration
(registration) and distribution of VLAN membership information.
A Brocade device enabled for GVRP can do the following:
• Learn about VLANs from other Brocade devices and configure those VLANs on the ports that
learn about the VLANs. The device listens for GVRP Protocol Data Units (PDUs) from other
devices, and implements the VLAN configuration information in the PDUs.
• Advertise VLANs configured on the device to other Brocade devices. The device sends GVRP
PDUs advertising its VLANs to other devices. GVRP advertises statically configured VLANs and
VLANs learned from other devices through GVRP.
GVRP enables a Brocade device to dynamically create 802.1Q-compliant VLANs on links with other
devices that are running GVRP. GVRP reduces the chances for errors in VLAN configuration by
automatically providing VLAN ID consistency across the network. You can use GVRP to propagate
VLANs to other GVRP-aware devices automatically, without the need to manually configure the
VLANs on each device. In addition, if the VLAN configuration on a device changes, GVRP
automatically changes the VLAN configurations of the affected devices.
