Differences between GVRP VLAN and VCMP VLAN

1

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.

GVRP mechanism on S series switch
The Generic Attribute Registration Protocol (GARP) provides a mechanism to propagate attributes so that a protocol entity can register and deregister attributes. The GARP VLAN Registration Protocol (GVRP) is used to register and deregister VLAN attributes. A manually configured VLAN is a static VLAN, and a VLAN created through GVRP is a dynamic VLAN. VLAN registration: adds a port to a VLAN. When a port receives a VLAN attribute declaration, it registers the VLAN specified in the declaration. VLAN deregistration: removes a port from a VLAN. When a port receives a VLAN attribute declaration, it deregisters the VLAN specified in the declaration.

Configuring communication between interfaces in different VLANs
A Fat AP can connect to a switch or router. If interfaces of a device are added to two VLANs, the interfaces can communicate with each other by default. If interfaces are added to two VLANs on different devices, routes need to be configured to enable communication between the interfaces.

What are the differences between network bridges and VLANs
Network bridges can implement packet forwarding at Layer 2 on the wide area network (WAN) side. Only Layer 2 interfaces can be added to virtual local area networks (VLANs). Only Layer 3 interfaces can be added to network bridges.

What are the differences between a bridge on an AR router and a VLAN
A bridge on an AR router can forward WAN packets in Layer 2. In addition, Layer-3 interfaces can be added into a bridge, which is different from a VLAN into which only Layer-2 interfaces can be added.

Add an interface to different VLANs
An access interface cannot be added to different VLANs. Run the port default vlan command to configure a default VLAN. A trunk interface can be added to multiple VLANs by running the port trunk allow-pass vlan command. A hybrid interface can be added to multiple VLANs in untagged or tagged mode by running the port hybrid untagged vlan or port hybrid tagged vlan command.
