Problems solved by technology

At present, there are two defects in this technology. One is that the SNMP manager must work all the time. If the server fails, it cannot manage the network equipment. That is to say, the SNMP management server is its only management channel. The second is that the SNMP server must know The IP address of the network device. If the address of the network device changes for some reason, the SNMP manager cannot manage the network device at this time.

Embodiment Construction

[0023] The specific implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples, but the protection scope of the present invention should not be limited thereby.

[0024] see figure 1 and figure 2 . The management method of the network equipment of the present invention comprises the following steps:

[0025] Step 1. Set the multicast IP address used by the LAN. The address 224.0.0.0 is reserved and not assigned, and 224.0.0.0 to 224.0.0.255 are permanent addresses, that is, the officially allocated 224.0.1.0 to 238.255.255.255 are multicast addresses available to users, valid for the entire network, 239.0.0.0 to 239.255. 255.255 is the local management multicast IP address, which is valid within a specific local range, so we generally choose the range from 239.0.0.0 to 239.255.255.255.

[0026] Step 2. All network devices in the local area network are added to the multicast IP address...

Abstract

The invention discloses a method for managing network equipment, comprising the following steps: step 1, setting a multicast IP address used by a local area network; step 2, adding all network equipment in the local area network to the multicast IP address; Step 3, setting management agreement; Step 4, described network management terminal sends UDP multicast packet to described multicast IP address, to search the network equipment in described local area network; Step 5, network equipment receives UDP multicast After the data packet, send its own information to the network management terminal; Step 6, the network management terminal sends a command to manage the network equipment. The method of the invention searches all network devices in the network through multicasting, obtains the IP address of each device, and can conveniently manage the network devices in the local area network, achieving the effect of management anytime and anywhere.

Description

technical field [0001] The present invention relates to User Datagram Protocol (UDP) multicast technology, in particular to a management method of network equipment, which is used for the management of network equipment produced by the same manufacturer in a medium-sized local area network. Background technique [0002] With the development of informatization, more and more units use informatization to carry out their work and purchase a large number of network equipment to form a local area network. A problem that comes with it is the management of network equipment. Due to the uncertainty of the physical location of network equipment, it is necessary to There is a server to manage the network devices in a unified way. At present, the widely used technology is to use the Simple Network Management Protocol (SNMP) protocol to manage the network devices. The SNMP management station is placed on the server, and the network device exists The SNMP client is used to receive SNMP c...
