Automatic allocation method of local area network ip address based on lldp and cloud computing center

Abstract

The present invention provides a method for automatically assigning IP addresses in a local area network based on LLDP, comprising the following steps: according to the networking plan, determining IP address resource configuration information in the local area network, uniformly numbering switches at the access layer, and generating key variable information of the IP addresses; Write the key variable information of the IP address into the access layer switch system description or system name, and open the LLDP service; the server receives the LLDP message sent by the access layer switch, and parses the serial number information of the switch port from the LLDP message and the key variable information of the IP address; the server generates its own IP address based on the parsed switch port serial number information and the key variable information of the IP address and configures it to the port. The method of the present invention only needs to configure the IP address and the specified system name or description information on the access layer switch port, and then the fixed IP address of each server can be automatically allocated through the LLDP protocol, improving deployment efficiency and reducing operation and maintenance workload.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an LLDP-based local area network IP address automatic allocation method and a cloud computing center. Background technique [0002] Abbreviations and definitions of key terms. [0003] Dotted and form, the full name is dotted decimal notation (Dotted decimal notation), which is the IP address identification method of IPv4. Each group of numbers is in decimal, and the groups are separated by . (dot), so it is called " dotted decimal". [0004] LLDP (Link Layer Discovery Protocol, Link Layer Discovery Protocol), used for devices from different vendors to discover each other in the network and exchange their own system and configuration information. It provides a standard link layer discovery method, which can organize the main capabilities, management addresses, device identifiers, interface identifiers and other information of the local device into different TLVs (Type / Len...

AI Technical Summary

Problems solved by technology

[0007] Problems in the existing technology: In the local area network of the cloud computing data center, multiple servers are connected to the access layer switch, and the corresponding private network IP address is configured on the server port

However, when the scale of the cloud computing data center is large, the efficiency of manual configuration is low, the workload is heavy, and error-prone
