A managed switch is a type of network switch that allows for greater control over the data traffic within a network. Unlike an unmanaged switch, which simply connects devices and forwards data, a managed switch provides features like traffic monitoring, VLAN support, and network security settings. This makes it ideal for businesses that need to optimize their network performance and manage multiple devices efficiently. Managed switches can be configured through a web interface or command line, enabling network administrators to customize settings according to their needs. They often support protocols like SNMP (Simple Network Management Protocol) for monitoring and managing network devices. This level of control helps ensure reliable communication and enhances overall network security.
