Simple Network Management Protocol, or SNMP in short, is a protocol used to manage different devices on an IP network. This protocol is mostly used to collect information about managed devices on IP networks and to use that information to change the behavior of these devices.
It is also used to identify devices, monitor the performance of your network, and to know the status of your network in real time.
SNMP scanning provides information about the different SNMP nodes in your network and using this information, you can stay on the performance of your network and the many devices that run on it.
As a network administrator, this is a must-have tool in your arsenal as it gives the basic information useful for identifying problems and for troubleshooting the same.
These are also some reasons to run an SNMP scan often, just to ensure that your network and all its devices are in good working condition.
