To block unauthorized access to switch ports, switches support a feature called port security. This feature allows you to configure which devices are allowed or blocked on each port. This number is the total of available MAC addresses, including those used for other Layer 2 functions and any other secure MAC addresses. Learn how to configure port security on Cisco switches to prevent unauthorized network access and pass your CCNA 200-301 exam.

Access switches typically operate at Layer 2 of the OSI model, forwarding data based on MAC addresses. However, many modern models also support basic Layer 3 functions such as static routing and limited dynamic routing, especially in high-performance or large-scale networks. This chapter provides details of Cisco tested access layer solutions in the enterprise data center. An enterprise network is a large network that may contain several campus networks spanning different. Introduction: The Hierarchical Network Model In today's complex IT environments, network design follows a structured approach to ensure. The access layer is where endpoints (such as phones, laptops, video-conferencing sets, printers, IoT sensors, IP cameras, and servers) are primarily connecting to the network. What is Distribution Layer and How to Choose Distribution Switch Multi-Gigabit Switch for Growing Enterprise Campus Network What is the main function of an access layer? What does an access layer switch do? How to choose the right network switch for the access layer? This post tells you everything.
