Describe Cisco''s Three Layer Hierarchical Model.

Access Layer Ethernet Switches

Access Layer Switches: Operating at the network's edge, access switches connect end-user devices like PCs, printers, IP phones, and wireless access points. They are characterized by high port density, cost-effectiveness, security features at the edge, and often PoE support. It typically sits at the access layer, provides high port density, often delivers PoE, and forwards traffic. The hierarchy Ethernet network is a three-layer integrated setup of networking devices. These networks are designed with three tiers that facilitate strategic installation, management, and maintenance, and so on. Access. When planning an enterprise access network, one of the most common dilemmas is whether to deploy Layer 2 (L2) or Layer 3 (L3) switches.
