Problems solved by technology

Since the VLAN attributes of some ports on the GVRP link are canceled, services between devices on non-faulty links on the ring will also be damaged to a certain extent. When no link is faulty on the ring, services between SW1 and SW4 Path: SW1, SW2, SW3 to SW4, when the link between SW3 and SW4 fails, the service between SW1 to SW4 will be switched to the path: SW1, SW6, SW5 to SW4, but because SW4, SW5 and The VLAN attributes of the ports on SW6 are inconsistent. Even if the link on this path is intact, service packets cannot be forwarded normally.
[0006] Therefore, on a GVRP link with two-way registration of VLAN attributes, when the GVRP intermediate link fails, even if the STP network performs a link switch, the VLAN attributes of some ports on the switched link will be canceled. Service packets cannot be transmitted normally

Abstract

This paper discloses a VLAN attribute registration method, including: configuring a linkage group according to the VLAN attribute registration direction of the GVRP device, and the linkage group is bound to two ports of the GVRP device, wherein one port is set as an uplink port, and the other port is set as an uplink port. Set as a downstream port; when the upstream port of the linkage group fails, solidify the existing dynamic VLAN under the downstream port of the linkage group into a static VLAN; send a statement registering VLAN attributes to the downstream device through the static VLAN. This paper also discloses a device for registering VLAN attributes, which can continue to realize two-way registration of VLAN attributes on the intact links on both sides of the fault point when the GVRP link fails, so that services can communicate normally on the switched links.

Description

technical field [0001] The invention relates to local area network switch technology, in particular to a VLAN attribute registration method and device. Background technique [0002] Generic Attribute Registration Protocol (Generic Attribute Registration Protocol, GARP) is a generic attribute registration protocol, which provides a means of dynamically distributing, propagating and registering certain attribute information between members in the same switching network. The attributes here may be characteristic information such as virtual local area network (Virtual Local Area Network, VLAN), multicast media access control (Medium Access Control, MAC) address and port filtering mode. [0003] GARP VLAN Registration Protocol (GARP VLAN Registration Protocol, GVRP) is an application protocol defined by GARP. It dynamically maintains the VLAN information in the switch based on the GARP protocol mechanism. All switches that support GVRP can receive VLAN registration from other swi...
