Abstract

The invention provides a method, a system and a device for achieving three-layer communication of a management message. The method comprises the following steps that a controlling bridge creates a first VME port with a first MAC address, and allocates a first IP address to the first VME port; a port extender creates a second VME port with a second MAC address; the port extender requests the IP address of the second VME port to the controlling bridge; the controlling bridge allocates a second IP address to the second VME port, and informs the second IP address and the first IP address to the port extender; the controlling bridge acquires the second MAC address of the second VME port in order to send the management message to the second VME port through three-layer communication and receivethe management message from the second VME port; and the port extender acquires the first MAC address of the first VME port in order to send the management message to the first VME port through three-layer communication and receive the management message from the first VME port.

Description

technical field [0001] The present application relates to the field of virtualization technology, and in particular to a method, system and device for realizing three-layer communication of management messages. Background technique [0002] The IEEE (Institute of Electrical and Electronics Engineers, Institute of Electrical and Electronics Engineers) 802.1BR standard protocol stipulates a port extension technology (Bridge Port Extension), which is a network device virtualization technology, and its core idea is to at least A PE (Port Extender, port extender) is connected to a CB (Controlling Bridge, control network bridge). Through configuration, each PE is virtualized into a remote service board of the CB, so that the CB performs unified management. [0003] The CB provided by the 802.1BR standard protocol is not rich enough for PE management, and the management messages of the CB and PE in the extended bridge system need to be realized through many private extended protoco...
