Problems solved by technology

This not only easily leads to low test efficiency, but also easily causes the risk of stable operation of the information system caused by modifying the switch configuration.
[0004] So far (December 10, 2015), the inventor has not retrieved the "method and system for network scanning with trunk protocol" in the State Intellectual Property Office (http: / / www.sipo.gov.cn / ) application

Embodiment Construction

[0059] see figure 1 , the method for network scanning based on the trunk protocol of the present invention, in the actual operation process, the specific implementation is as follows:

[0060] 1) The test system obtains and saves the switch configuration, and automatically analyzes the obtained switch configuration information to obtain the VLAN and network segment information on the switch, and stores the VLAN number and network segment information used on the switch.

[0061] The acquisition and saving of the switch configuration above can be achieved in the following ways:

[0062] A) The test system connects to the switch through any method such as console interface, telnet network login, ssh network login, etc., and obtains the switch configuration through the configuration reading command;

[0063] B) The test system obtains switch configuration information through snmp query;

[0064] C) The test system imports the switch configuration information to the test system ...

Abstract

A method for network scanning based on the trunk protocol, comprising the steps of: 1) switch configuration acquisition and analysis; 2) setting a test port as a trunk mode; 3) constructing and sending a test packet; 4) receiving and filtering a response packet; 5) ) data restoration and processing. The present invention also relates to a network scanning system based on the trunk protocol dedicated to the method, including the following sequentially connected modules: 1) switch configuration acquisition and analysis module, 2) setting the test port as a trunk mode module, 3) constructing and sending the test Data packet module, 4) receiving and filtering response data packet module and 5) data restoration and processing module. By adopting the method and system of the present invention, all VLANs or network segments on the switch can be scanned at one time without modifying the configuration of the switch, which can effectively improve the network scanning efficiency and avoid changing the configuration of the switch from affecting the stable operation of the information system.

Description

technical field [0001] The invention relates to a method for network scanning based on the trunk protocol. The invention also relates to a network scanning system based on the trunk protocol which is specially used for the method. [0002] technical background [0003] At present, all kinds of network scanners on the market use the access interface of the access switch to scan the network when scanning the network, which leads to the fact that the scanner can only scan the network for a single VLAN or network segment of the information system each time. If there are multiple VLANs or network segments on the switch of the information system, the tester needs to change the access port where the network scanner is connected to the switch to test again. And this easily leads to low test efficiency. If the switch does not have an idle access interface for certain VLANs or network segments, the tester must either give up the test for the network segment, or change the switch conf...
