Physical and Data Link Layer Functionality While the switch function is primarily associated with the data link layer, it also handles the physical layer aspects of network communication. It regenerates the electrical signal to extend the effective range of the network cable without degrading the signal quality.
Network Switch Function Scalability Planning and Implementation
Furthermore, advanced features like Access Control Lists (ACLs) and port security integrate directly into the switching function, providing hardware-level security that filters unauthorized access attempts before they reach the core network. Modern switches allow for simultaneous transmission and reception, effectively doubling the potential throughput between connected devices.
Every network interface card possesses a unique MAC address, and the switch maintains a dynamic table known as the MAC address table. Conversely, a managed switch offers administrators granular control over the network, allowing for adjustments to Quality of Service (QoS), port mirroring, and virtual LANs to optimize performance and security.
Network Switch Function Scalability Planning for Future Growth
This segmentation prevents network noise from affecting unrelated segments and limits the scope of network scans or attacks. In half-duplex environments, devices must wait their turn to talk, creating bottlenecks.
