Briefly describe how SNMP works.
What will be an ideal response?
The Simple Network Management Protocol (SNMP) is a protocol used to manage networked equipment. These devices include not only core network devices such as switches, routers, hubs, bridges, and wireless APs, but also printers, copiers, fax machines, and even uninterruptible power supplies (UPSs). Each SNMP-managed device must have an agent or a service that "listens" for commands and then executes them. These agents are protected with a password known as a community string in order to prevent unauthorized users from taking control over a device. There are two types of community strings: a read-only string will allow information from the agent to be viewed, and a read-write string allows settings to be changed.
