Generic Attribute Registration Protocol (GARP)
GARP helps to automate the configuration in several switches.
GARP works under CIST (Common and Internal Spanning Tree).
GVRP is an application of GARP. GVRP is like VTP.
Like VTP all devices in the same LAN maintain the same VLANs.
GVRP is used to managed VLAN information and use GARP packet to do it.
Devices the same as VTP register and started to work in a server-client architecture.
The devices can be register in three ways:
|
Normal |
Transmit the Static and Dynamic VLANs (Static are manually created. Dynamic are learned from other). THIS IS THE DEFAULT MODE |
|
Fixed |
Only transmit Static VLANs. If a trunk port is configured in this way only static VLAN are allow it even when dynamic VLAN are allow it. |
|
Forbidden |
Only VLAN 1 is permitted even when more VLANs are allow it in the Trunk. |
