Problems solved by technology

However, it is cumbersome to operate at present, because it needs to be configured separately to achieve their respective isolation functions
Sometimes it is more cumbersome to switch from one isolation technology to another isolation technology according to actual needs, and it is even necessary to turn off one of the isolation functions to complete the other isolation through configuration
In this way, the work efficiency is relatively low, and there is no efficient way to perform data processing switching operations

specific Embodiment 1

[0018] See figure 1 , the application of port isolation and VLAN isolation switching method of the present invention in EPON terminal, OLT equipment 1 connects ONU equipment 3 through optical splitter 2, and each port of ONU equipment 3 connects PC 4 respectively, and in the present embodiment, PC 4 There are 4, namely PC1, PC2, PC3, PC4.

[0019] When setting VLAN isolation, the OLT device controls the ONU device, configure port Port1 and port Port2 as VLAN 100, configure port Port3 and port Port4 as VLAN 200, port Port1 and port Port2 of the ONU device are set to the same VLAN, port Port3 and port For the same VLAN, in this way, port Port1, port Port2, port Port3, and port Port4 are set as VLAN isolation, so that port Port1 and port Port2 form a group, port Port3 and port Port4 form a group, and between port Port1 and port Port2 Can communicate, port Port3 and port Port4 can communicate, so PC1 and PC2 can communicate, PC3 and PC4 can communicate, port Port1 and port Port3,...

Abstract

The invention provides a port isolation and VLAN isolation switching method, which completes switching between port isolation and VLAN isolation flexibly and efficiently, enables a user to use more simply and more conveniently and is higher in work efficiency. The port isolation and VLAN isolation switching method comprises the steps that port isolation is performed, that is, VLANs of ports requiring port isolation are set to be different so as to enable the ports not to perform communication therebetween; VLAN isolation is performed, that is, VLANs of ports requiring VLAN isolation are set to be identical, so that the ports of the same VLAN can perform communication therebetween, and the ports of different VLANs cannot perform communication therebetween; when VLAN isolation is switched to port isolation, the VLANs of the ports requiring port isolation are changed from the same VLAN into different VLANs; and when port isolation is switched to VLAN isolation, the VLANs of the ports requiring VLAN isolation are changed from different VLANs into the same VLAN. The invention further provides an application of the method in an EPON terminal.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to port isolation and VLAN isolation switching methods and their application in EPON. Background technique [0002] The port isolation technology is to realize the isolation between messages, and isolate different ports through configuration so that data communication cannot be performed between each port; the VLAN isolation technology is also to realize the isolation between messages. It is a technology to isolate data from different ports by configuring VLAN so that data communication between ports cannot be performed. [0003] Currently, port isolation technology and VLAN isolation technology are two different technologies, but their fundamental purpose is to isolate data between ports by configuring ports. However, it is cumbersome to operate at present, because they need to be configured separately to achieve their respective isolation functions. Sometimes it is more...
