Differences between GVRP VLAN and VCMP VLAN
"VLAN Central Management Protocol (VCMP) is located at the Layer 2 of OSI model. It propagates VLAN information within a Layer 2 network and ensures VLAN information consistency on the Layer 2 network.
The GARP VLAN Registration Protocol (GVRP) is used to register and deregister VLAN attributes. The Generic Attribute Registration Protocol (GARP) provides a mechanism to propagate attributes so that a protocol entity can register and deregister attributes. GARP transmits attributes.
The VLANs on S series switches, except S1700 and S9300 are as follows:
1. GVRP creates dynamic VLANs, whereas VCMP creates static VLANs. When you run the display vlan summary command, the VLAN of GVRP displays Dynamic vlan and the VLAN of VCMP displays Static vlan.
2. VCMP can only help network administrators synchronize VLAN configurations, but cannot dynamically add interfaces to VLANs. GVRP can simplify VLAN configuration and is able to dynamically add interfaces to VLANs."
