Dimension ES-2008 Ethernet Switch
9-2 VLAN
Dynamic VLANs
GARP VLAN Registration Protocol (GVRP) is a Generic Attribute Registration Protocol
(GARP) application that provides VLAN registration services through dynamic
configuration (or registration) and distribution of VLAN membership information across
the network.
With GVRP, the switch is able to register necessary VLAN members to create IEEE
802.1Q-compliant VLANs on links with other devices that are running GVRP. GVRP
automatically provides consistent VLAN ID across the network to reduce VLAN
configuration errors. GVRP propagates VLAN information 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.
