How SNMP Works | Network Fundamentals Part 24

We can manage proactively, and we can manage reactively. SNMP is a protocol that can help us with both. A management server will use SNMP polling to collect information from devices on our network. This builds charts and dashboards to help us evaluate the health of our network. If a device has a problem, it may even send an SNMP trap to the management server. The server can then take an appropriate action, like alert us. SNMP information is stored in a hierarchical structure called a MIB (Management Information Base). This is a collection of objects called OIDs (Object Identifiers). These describe the information that can be collected from devices, and how to interpret it. When a poll is sent, the server will also specify a community string. This string is a simple form of authentication. Unfortunately, it is stored in plan-text, both in the message and in the configuration. There are three versions of SNMP. v1 came first, and v2 extended this by adding support for 64-bit counters. v3 added real authentication and encryption. v3 is recommended in most cases.
