Which function is supplied by the access layer in a three-layer network design?
Answer: The major goal of the devices present in the access layer is to provide network access to the users. While the services provided by the distribution layer are routing and the policy functions. The core layer is responsible for the backbone connectivity.
Along with the diversity in technology, it also become complicated to handle. For the reliable infrastructure of the network, Cisco has discovered the three-layer hierarchical model, which helps to design, maintain the scalability, reliability and also reduce the cost of developing the network.it has three with its features. The layer is listed below:
The first layer is the access layer which allocates the end-user access to the network.it also works by connecting the end devices as PCs, IP phones, printers, and scanners with the network. The end-user devices in the network use a different kinds of protocols to find each other, eliminate the loops and also exchange the information. Different kinds of services are the security policies are configured and implemented in this access layer.
Some of the access layer functions are described below:
The switches which are connected in this layer are called access switches. The End-devices in the LAN network is connected with the help of these switches.in simple words, the access switch work by moving the traffic between the connected devices and the LAN.
