SNMP Ports: TCP vs UDP

-
The Simple Network Management Protocol (SNMP) is a very popular communications protocol in remote monitoring applications, so it's likely you'll work with it at some point or are already working with it.
As a monitoring solutions provider, we provide custom SNMP monitoring devices and, because of that, we usually get many questions about SNMP monitoring. Some of these questions include: "What port does SNMP use?" or "Does SNMP use TCP or UDP?"
In this video, Andrew will talk about these common questions to help you when you're configuring your SNMP gear.

Great and concise video. I thought I had a general idea on how it worked but this really polished it for me. Thanks

SNMP is a request/response protocol. UDP port 161 is its well-known port. SNMP uses UDP as its transport protocol because it has no need for the overhead of TCP. "Reliability" is not required because each request generates a response. If the SNMP application does not receive a response, it simply re-issues the request. "Sequencing" is not needed because each request and each response travels as a single datagram.

The request and response messages that SNMP sends in the datagrams are called Protocol Data Units (PDU). These message types allow the manager to request management information, and when appropriate, to modify that information. The messages also allow the agent to respond to manager requests and to notify the manager of unusual situations.

Can you explain why we UDP is more preferred than TCP

Are you writing backwards? that's amazing if you are
