Main features of SNMP Network Management

SNMP network management is one of the most handy tools for IT administrators. What are the management functions of this management tool? The following describes the basic concepts. The Simple Network Management Protocol (SNMP) is first proposed by the research team of Internet Engineering Task Force (IETF) to solve the router management problem on the Internet. Many people think that Linux SNMP runs on the IP address because the Internet runs the TCP/IP protocol, but this is not the case.

The SNMP protocol is designed to be unrelated to the protocol, so it can be used on IP addresses, IPX, AppleTalk, OSI, and other used transport protocols.

Linux SNMP is a series of protocol groups and specifications that provide a method to collect Network Management Information from devices on the network. Linux SNMP also provides a way for devices to report problems and errors to network management workstations.

SNMP network management includes five functions: fault management, configuration management, billing management, performance management, and security management.

(1) fault management is one of the most basic functions of SNMP protocol network management. Network Fault management includes fault detection, fault isolation, and fault rectification. It includes the following typical functions: maintain and check error logs, accept error detection reports, and respond, track, identify errors, perform diagnostic tests, and correct errors.

(2) configuration management is the most basic SNMP protocol network management function. It is responsible for network establishment, business expansion, and maintenance of configuration data, including resource list management, resource activation, and service activation.

(3) billing management records the use of network resources to control and monitor the costs and costs of network operations. The purpose of billing management is to calculate and collect the user's fees for using network services, calculate the utilization rate of network resources, and calculate the cost-effectiveness of the network.

Billing management includes the following functions: Calculation of network construction and operation costs, statistics of the utilization of the network and its resources, online collection of Billing Data, calculation of network service fees payable by users, and billing management.

(4) Performance management aims to maintain the network quality of service (QoS) and network operation efficiency of the SNMP protocol. Therefore, it is necessary to provide the performance monitoring function, performance analysis function, performance management control function, and performance database maintenance function.

(5) Security management uses information security measures to protect systems, data, and services in the SNMP protocol network. Security management aims to provide information privacy, authentication, and integrity protection mechanisms to protect services, data, and systems on the network from intrusion and damage.
