Abstract

The present invention is applicable to the field of communication, and provides a device for realizing automatic switching of Ethernet topology. Chip and a plurality of physical layer PHY chips, the control communication interface is used to operate the device to realize automatic switching of Ethernet topology; the microprocessor is used for receiving and processing instructions and returning results, and is also used for generating and maintaining network Interface forwarding table, and control the MAC switching chip to change the corresponding network interface forwarding rules; the network interface forwarding table is in units of groups, each network interface can only be in one group, for all network interfaces in a group, each network Interface traffic is forwarded to all other network interfaces. The invention can realize the automatic switching function of the Ethernet topology without manual operation, and can also realize wire-speed forwarding, and under the condition of ensuring the performance, the topology transformation is flexible, the management is convenient, and the real-time configuration is convenient.

Description

technical field [0001] The invention relates to the communication field, in particular to a device and a method for realizing automatic Ethernet topology switching. Background technique [0002] In an Ethernet network, especially in an Ethernet topology for testing, it is often necessary to adjust the topology of the Ethernet. The solution in the prior art is to use a switch to divide two ports of the switch into one 802.1Q virtual local area network (Virtual Local Area Network, VLAN), and to re-divide the other two ports into one 802.1Q VLAN during topology switching. For example, devices under test 1 and 2 are respectively connected to port 1 and port 2 of the switch, and devices under test 3 and 4 are connected to ports 3 and 4 of the switch. In topology I, port 1 and port 2 are divided into one 802.1Q VLAN , port 3 and port 4 are assigned to another 802.1Q VLAN for topology switching. In topology II, the 802.1Q VLAN is reclassified. Another 802.1Q VLAN. [0003] Howev...
