Difference between SNMP and SMTP

SNMP vs SMTP


In the area of ​​networks, there have been many suites of contradictory protocols. However, as of now, TCP / IP is the most used protocol stack in the world. Indeed, it was released at the right time with the right version control and the protocol suite included many protocols to meet the needs of those days. The interesting feature of a protocol suite is that it is possible to add new protocols to this stack; which means that all the protocols used will never be out of date unless a major change in the protocol suite occurs. SNMP and SMTP are protocols used with the TCP / IP protocol stack. Simply put, These two protocols were introduced by the Internet Engineering Task Force (IETF) via RFC 1157 and 821 respectively. RFCs are actually a way of collecting contributions from interested parties. After examining and refining them by experts, they have become standards. SNMP and SMTP are two of these standards.

What is SNMP?

SNMP stands for Simple Network Management Protocol. As its name suggests, it manages various devices connected to a TCP / IP network. There are three levels in this protocol. The SNMP manager, the SNMP agent and the managed device. The SNMP manager is essentially a controller, while the SNMP agent acts as an interface between the devices and the network. The managed device is the device controlled by the previous two.

The communication process occurs with a set of commands inherent in the protocol. These commands must be understood by the three levels of the protocol in order for any communication to take place. For example, using the GET command, the SNMP manager can acquire information from a device. Managed devices can include PCs, routers, servers and switches, etc.

What is SMTP?

SMTP stands for Simple Mail Transfer Protocol. It covers methods of sending and receiving email from one client to another over the Internet. It covers a wide range of mail servers and applications used to send / receive emails. When you compose and send mail, the SMTP client communicates with the mail server and verifies the email and destination information. Then, the SMTP server sends your mail to the destination and its SMTP client manages the reception process in the same way.

In essence, you can think of SNMP as a service that manages your incoming and outgoing e-mail securely over the Internet. Modern versions of the same protocol also define the use of Mail Transfer Agents (MTAs), which act as a proxy between sending and receiving mail applications.

Conclusion of SNMP and SMTP

SNMP and SMTP are two standards that work in harmony to achieve two different tasks. They operate so that they can control SMTP servers and MTAs via SNMP managers. In addition, SNMP managers are able to send alerts via SMTP mail servers.
