Simple Network Management Protocol SNMP

Simple Network Management Protocol or SNMP is the most famous networking protocols in the market. Network admins already know about components like SNMP traps, SNMP Agents and Managers. SNMP will help you in managing your network devices like printers, servers, and routers. If your network has SNMP capability, then you can use it for collecting information. Also, it will help you in monitoring your device.

You can use the SNMP protocol to monitor network traffic and your infrastructure health. Also, you can use it for measuring your network performance. The concept behind this protocol is very simple. In this article, we are going to talk about SNMP.

Definition of SNMP:

SNMP is a network protocol. If you are using SNMP, then your devices can communicate with other devices. There are many different versions of SNMP in the market. Currently, most people are using SNMP V3. You can use it for identifying devices in your network. Also, it will help you in monitoring the performance of your whole network.

However, SNMP will work only with the devices that are compatible with it. Thus, you need devices that are compatible with SNMP. There are many manufacturers that are working on SNMP products. Thus, you don’t need to worry about compatibility issues.

How do SNMP works?

SNMP uses various components for monitoring networks. The main four parts of SNMP are:

  • SNMP devices
  • SNMP Agent
  • SNMP Manager
  • MIB or Management Information Base

SNMP is using the client-server model. The SNMP Manager is the main component of SNMP. It is responsible for receiving data from the devices. There are many different SNMP managers available. Also, most of these managers are free.

The SNMP agents are special programs that are written inside your hardware. It is responsible for collecting data like disk space and bandwidth. After that, it sends the data to the MIB or Management Information Base. SNMP device mostly acts as an agent. They are responsible for collecting important data like bandwidth. The Agent and the Manager are always communicating with each other.

Benefits of SNMP

There are many advantages to using SNMP. The best thing about SNMP is the visibility it offers. You can use SNMP monitoring tools for monitoring your whole network. This will help you in fixing performance issues. Some of the main benefits of using SNMP are:

  • Open Protocol

SNMP is completely an open protocol. This is the most important benefit of using SNMP. An open protocol ensures that SNMP is not a property of any vendor. Thus, many vendors support this protocol. If you are using a proprietary protocol, then you will always depend on the vendor. SNMP has various different vendors available in the market. Thus, you can choose the best technology for your network.

  • SNMP Traps

SNMP Traps will send you alerts about your network devices. If there is any fault in your device, then it will inform the SNMP manager. This will ensure that you know about every issue in your network. There are many different parameters that you can use in SNMP Traps. Thus, you can customize it according to your needs.

  • Fault Management

SNMP is a perfect solution for managing your network. Most network admins are already using it for managing their network. SNMP traps will ensure that you are up-to-date. It will help you in monitoring the health of your devices. SNMP traps will send your important details. Your SNMP manager will help you in solving problems in your network.

Disadvantages of SNMP

There are still some disadvantages of using SNMP. SNMP mainly lacks in areas like security and scalability. It doesn’t work smoothly with larger workloads. If you are using older versions, then you are vulnerable to various attacks. Some of the main disadvantages of using SNMP are:

  • Scalability

This is the main problem of using SNMP. SNMP can’t receive a huge amount of data from devices. SNMP is very good at translating the data it receives. However, it doesn’t work with a large amount of data. Thus, you can’t use it with your routing table. If you want complete visibility, then SNMP is perfect for you.

  • Security

This is another main issue with SNMP. SNMP V3 is using good encryption algorithms. However, SNMP V2 and V1 are still vulnerable to many attacks. These versions don’t have any security features. They don’t use any encryption algorithm. Thus, it is very easy to attack these versions. If you are using SNMP V3, then you need to configure it properly. Otherwise, it is very easy to crack into SNMP devices. If attackers can hack into your SNMP manager, then they will get access to your whole network.

You can minimize the security risks by using V3. It is also important to change the default settings of your tools. Also, you should configure your SNMP to read-only mode. If you are using old SNMP Version, then you should upgrade to the latest version. This will help you in reducing the risks.

  • SNMP-Enabled Devices

If you want to use SNMP, then you need SNMP-enabled devices. You can’t monitor other types of devices by using the SNMP manager. Thus, network monitoring tools are using various protocols to deal with the visibility issue. If you are using SNMP monitoring tool, then make sure that you are using SNMP-enabled devices.

Conclusion

SNMP is the most famous open protocol in the market. Most network administrators are using it for monitoring their networks. SNMP monitoring tools will help you in monitoring your devices. There are many advantages to using SNMP. However, you should also use the right security configurations. This will help you in protecting your network from attackers. There are many SNMP monitoring tools available in the market. It is important to find a good monitoring tool for your network. This will ensure that you can easily understand the complex data.
