An SNMP scanner works by sending SNMP (Simple Network Management Protocol) requests to network devices to collect information about their status, configuration, and performance. These requests are typically sent using UDP or TCP/IP protocol.
The scanner starts by scanning the IP address range of the network to identify SNMP-enabled devices. Once a device is identified, the scanner sends SNMP queries to the device’s SNMP agent to request information from its MIB (Management Information Base). The MIB is a database that stores information about the device’s configuration, performance, and status.
The scanner can then analyze the information gathered from the device to identify any potential issues, such as high CPU usage, high bandwidth utilization, or configuration errors. It can also use the information to monitor the device’s performance over time and detect any changes that may impact its performance or availability.
SNMP scanners are commonly used by network administrators to monitor and manage their network infrastructure. They can help identify and resolve issues before they cause downtime or other problems for users.
