Abstract
The invention discloses a method for automatically finding and monitoring devices in a local area network. The method includes the steps of determining the operating devices and medical access control (MAC) information of the operating devices in a network environment by sending an internet control messages protocol (ICMP) packet, acquiring route information through a simple network management protocol (SNMP) to determine a topological structure, and achieving device monitoring through the SNMP and known object identifier (OID) information of each manufacturer device. By means of the method, all the devices in the local area network and topological information of the devices are automatically found, information such as manufacturers and types of the network devices can be obtained, centralized management of network management staff is facilitated, and the network management staff can achieve automatic network device entering through the method and find illegal device access and abnormal device connection; by means of the method, centralized monitoring of central processing units, hard disks, memory use rates, flow information of internet access, installed service information and the like of the devices can be achieved, so that the network management staff can rapidly and conveniently find faults or abnormal information in the network.
Description
Technical field
The present invention relates to Network Monitoring Technology field, relate in particular to the method for the interior automatic device discovery of a kind of local area network (LAN) and monitoring.
Background technology
SNMP is the network management standard based on TCP/IP protocol suite, and its predecessor is simple gateway monitoring protocol (SGMP), is used for communication line to manage.Simple Network Management Protocol (SNMP), standard by a group network management forms, and comprises an application layer protocol (application layer protocol), database model (database schema) and one group of resource object.This agreement can network enabled management system, and whether the equipment being connected on network in order to monitoring has any upper situation about paying close attention to of management that causes.
Network Development scale is increasing in recent years, access device, transmission equipment and host number in network is to approach the rate increase of index, make network management personnel's workload and work difficulty increasing, concentrate efficient network management just to seem particularly important, the present invention realizes the centralized management without installation agent by general snmp protocol and ICMP agreement, has reduced greatly webmaster personnel's workload and work difficulty.
Summary of the invention
The object of the invention is the defect in order to overcome prior art, the method for the interior automatic device discovery of a kind of local area network (LAN) and monitoring is provided, thereby is convenient to automatic device discovery and monitoring.
A kind of method of automatic device discovery and monitoring in local area network (LAN), it is according to examine network IP range section, determine equipment and the MAC information thereof in operation in network environment by sending ICMP protocol package, then obtain routing iinformation by snmp agreement and determine topological structure, and by snmp agreement and known each vendor equipment OID information realization monitoring of tools, be specially:
According to examine network IP range section, send ICMP bag, the respond packet of returning according to equipment, whether judgment device exists or is communicated with, overtimely do not receive that respond packet illustrates that this IP does not exist or obstructed, resolve the ICMP respond packet of receiving, obtain device mac address.
To the equipment being communicated with, read public OID:1.3.6.1.2.1.4.1.0 by snmp and judge whether it has routing function, the equipment that has routing function may be router or senior switch, and routing device is obtained to whole network topology structure by snmp.
To the equipment being communicated with, by snmp and known each vendor equipment MIB storehouse, the various state informations that get equipment realize monitoring of tools.
The beneficial effect that technical solution of the present invention is brought:
1, network management personnel can realize all devices in automatic detecting network environment by this invention, and this topology of networks, thereby can help network management personnel to realize automatic equipment typing, the equipment of typing is carried out to centralized management, and be convenient to network management personnel and find that whether illegal network insertion is connected the information such as normal with network.
2, network management personnel utilizes the method can also realize the centralized monitor to equipment, the CPU of watch-dog, hard disk, memory usage, the flow information of network interface, the information on services of installation etc., have avoided webmaster personnel to check by hand each station server, or by the loaded down with trivial details mode of traditional installation agent, allow webmaster personnel fault or the abnormal information in discovering network more quickly and easily.
