How do SNMP work for E-Lins router

 

SNMP is the communication protocol between management process (NMS) and Agent. SNMP is the predecessor of simple gateway monitoring protocol (SGMP), which is used to manage communication lines. It provides a standardized management framework for monitoring and managing devices in a network environment, a common language for communication, and corresponding security and access control mechanisms. Network administrator can query device information, modify device parameter value, monitor device status, automatically discover network fault, generate report, etc.

 

SNMP is specifically designed for use in IP network management network nodes (servers, workstations, routers, switches, and HUBS, etc.) of a standard protocol, it is an application layer protocol. SNMP enables network administrators to manage network performance, discover and solve network problems, and plan network growth. SNMP receives random messages (and event reports) from the network management system to learn of network problems.

Subsequently, SGMP has been greatly modified, especially by adding SMI and MIB that conform to the definition of Internet. The improved protocol is known as SNMP. The framework of SNMP network management based on TCP/IP is the current standard in the industry. It consists of three main parts, namely, SMI (Structure of Management Information), MIB (management Information base) and SNMP (management protocol).

SNMP has the following technical advantages:

UDP is the standard protocol based on TCP/IP Internet.

Automated network management. Network administrators can use SNMP platform to retrieve information, modify information, find fault, complete fault diagnosis, capacity planning and report generation.

Shield the physical differences of different equipment, realize the automatic management of products from different manufacturers. SNMP only provides the most basic set of functions, making management tasks relatively independent from the physical characteristics and actual network types of managed devices, so as to realize the management of devices from different manufacturers.

The simple request-reply mode is combined with the active notification mode, with timeout and retransmission mechanism.There are few types of messages, and the message format is simple, convenient to analyze and easy to implement.The version of Pv3 provides authentication and encryption security, as well as user and view-based access control to enhance security.

All of E-Lins 4g routers can support SNMP, the protocol between agent and NMS. Such as Mini size but popular model H685 router, which is robustness, reliability, security, friendly-using, and competent to be engineered to protect against extreme temperatures, humidity, shocks, vibrations, dust, reverse polarity, and transient voltage, which is widely used in more than twenty industrial fields, such as CCTV security surveillance, AMR, vehicle, retails, vending machines, power control, water schedule, traffic, oil field, weather forecast, environmental protection, street lamp control, post, bank and many other fields.

We can also provide NMS for customer use for free, customer can use NMS with their own Server. If interested in E-Lins best 4g router please feel free to contact us.
