Embodiment Construction

[0037] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0038] The invention mainly aims at that the network equipment has only one port, and a plurality of Modems are connected under the port, and the general loopback detection method cannot meet the requirements, thus a new loopback detection method is proposed.

[0039] figure 2 It is a block diagram of a VLAN-based loop detection method provided by an embodiment of the present invention, such as figure 2 shown, including the following steps:

[0040] Step S201, configuring different VLANs for each Modem under one port of the network device.

[0041] Step S202, the network device respectively generates the loopback detection message of each Modem, and s...

Abstract

The invention discloses a VLAN-based loopback detection method and network equipment. The method includes configuring different VLAN for each Modem of one terminal of the network equipment; allowing the network to generate and send loopback detecting pocket of each Modem in the VLAN where each Modem located; allowing the network equipment to receive pockets from different VLAN through each Modem and judge whether the pockets are loopback detecting pockets or not; if so, finding the Modem corresponding to the loopback detecting pockets to disconnect the Modem. According to the method and the network equipment, when one terminal of the network is connected to multiple Modems, loopback of one Modem occurs, normal operating state of the entire network equipment is free of influences.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a loopback detection method and related equipment based on a virtual local area network (Virtual Local Area Network, VLAN). Background technique [0002] With the development of communication technology, the network coverage area is getting larger and larger. Ethernet access has become one of the most economical ways of broadband access. Ethernet access equipment, that is, network equipment, has also become the most common equipment for broadband access. one. [0003] There are usually multiple modems connected to the network equipment for user access. When a user builds a private network through a hub or a switch under the Modem port, a loopback may occur due to negligence in networking, and eventually cause a broadcast storm, affecting other users' access to the Internet. For this situation, a common practice is to construct a special loopback detection message,...
