Importance of Generic Attribute Registration Protocol (GARP)
In a large network, it is not practical to register and de-register the attribute values of switching devices associated in the network. To overcome the difficulty IEEE defines a new protocol which works in layer 2. The new protocol is named as Generic Attribute Registration Protocol or simply GARP.
Definition of Generic Attribute Registration Protocol
Generic Attribute Registration Protocol (GARP) is a generic framework defined by the IEEE to provide bridges, switches, or other similar devices to be able to register and de-register attribute values, such as VLAN identifiers and multicast group membership across a large LAN.
How to implement GARP
To implement GARP, a GARP application has to be created. The best example for GARP application is GVRP. GVRP stands for GARP VLAN Registration Protocol. GVRP creates dynamic VLANs when GARP is enabled on the switch.GVRP is used for propagating VLAN information between switched where VLAN is implemented.
Configure GARP
To enable GARP application the command used is :
ENABLE GARP=GVRP [STP={stp-name|ALL}]
To disable GARP application the command used is:
DISABLE GARP=GVRP [STP={stp-name|ALL}]
Suggested Readings
1. Internet Group Management Protocol (IGMP)
2. Address Resolution Protocol (ARP)
3. Dynamic Host Configuration Protocol (DHCP)
4. Internet Control Message Protocol (ICMP)
