SNMP, or Simple Network Management Protocol, is vital for managing network elements like routers, switches, and printers. It utilizes a manager-agent model and a Management Information Base (MIB) for data retrieval. SNMP allows querying devices for data, setting alarms, and aiding in growth planning. Object Identifiers (OIDs) uniquely identify objects in the MIB hierarchy, while community strings act as passwords for device access. SNMP operates over UDP and supports various versions, with SNMPv3 offering enhanced security features.
