Problems solved by technology

[0008] After the Ethernet interface supports basic Layer 2 and Layer 3 switching, service management can be carried out based on ports, Layer 2 port switching, and Layer 3 port routing after termination, but the granularity of business management is not fine enough, and the processing is still not flexible enough. The port cannot realize the function of some services through Layer 2 switching and some services through Layer 3 routing

Embodiment Construction

[0038] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0039] figure 1 It is a schematic diagram of the network hierarchy of the TCP / IP model applied in the present invention, as shown in the figure: the common second and third layer network devices in the TCP / IP model are mainly switches and routers, which correspond to the link layer and network in the model respectively Floor. These devices perform protocol processing and message forwarding according to specific rules at their respective network levels, and they also manage network traffic according to their respective network levels. In order to improve networking flexibility and adapt to complex environments during actual networking, it is necessary to dynamically adjust port protocols and forward...

Abstract

The invention relates to a method of Ethernet interface to simultaneously support routing function and switching function. The method includes that: an Ethernet interface is configured into a route attribute interface; a sub interface of route attribute Ethernet interface is created, and VLAN is utilized to encapsulate the sub interface; the route attribute Ethernet interface is divided into layer 2 VLAN, wherein the VLAN identification of the route attribute Ethernet interface when being divided into the layer 2 VLAN is different from the VLAN identification of the sub interface; and whether processing is carried out on layer 2 or on layer 3 is determined according to the VLAN identification carried in the received message and the VLAN attribute configuration of the Ethernet interface.The method of the invention can realize that an Ethernet interface simultaneously supports routing function and switching function, and meanwhile flexibility of networking and application can be improved.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a method for an Ethernet interface to simultaneously support a routing function and a switching function. Background technique [0002] The well-known IP (Internet Protocol, Internet Protocol) network adopts the TCP / IP layered model. This approach enables each layer to achieve its own specific functions. It not only clearly defines the function set of each layer, but also controls the complexity of implementation. It also diversifies the selection of devices at each layer when networking. [0003] Common network devices in the TCP / IP model mainly include transmission devices, switches, and routers, which correspond to the physical layer, link layer, and network layer in the model respectively. These types of devices perform protocol processing and message forwarding according to specific rules at their respective network levels, and they also manage network traffic according to...
