In a typical enterprise network architecture, the access layer switch is the first point of contact between end-user devices and the rest of the network. These switches connect endpoints such as PCs, printers, VoIP phones, and wireless access points, enabling user traffic to enter the LAN. It assists mainly in the switching of incoming and outgoing data packets to the right destination, as specified in MAC. In this layer, the layer 2 switches are installed to distribute the data packets to the addressed group of access devices. The layer 2 switches prevent over-crowding of data packets in transmission links and access devices. Wireless access points are also connected here and provide further access. FortiSwitch units distribute the ports to plugs. This layer serves as the network's outermost boundary and the gateway through which all data must pass. This layer is primarily composed of devices like access switches and wireless access points.
