Which layer is the access layer switch on

This layer usually incorporates Layer 2 switches and access points that provide connectivity between workstations and servers. You can manage access control and policy, create separate collision domains, and implement port security at this layer. For example, a switch that provides access-layer functionality is called an access switch, a switch that operates in the distribution layer is known as a distribution switch, and a switch that operates in the core layer is called a core switch. This layer serves as the network's outermost boundary and the gateway through which all data must pass. Selecting the right switch type has a direct impact on network scalability, performance, and management efficiency. [pdf]

Why do switches perform port aggregation

Port aggregation allows you to group multiple physical ports into one unit. The following list details the basic. All UniFi Switches support aggregation, except USW-Flex, USW-Flex-Mini and USW-Ultra. Because of this, you should not aggregate two ports connected from a. Switch aggregation, also known as link aggregation or trunking, is a method used in computer networking to combine (aggregate) multiple network connections in parallel. Link aggregation increases total bandwidth beyond what a single connection could sustain, and provides redundancy where all but one of the physical links. Port Aggregation Protocol or PAgP is an EtherChannel technology that is a Cisco proprietary protocol. [pdf]

What connection method is used for the aggregation switch

Aggregation switches handle link aggregation by using LACP or Static Link Aggregation protocols. LACP is a dynamic protocol that automatically discovering and configures aggregated links between switches. An aggregation switch is a network device that consolidates traffic from multiple access switches, wireless access points, or other edge devices and forwards it to core switches or routers. You may also. An Aggregation or "Top-of-Rack" switch is designed to connect everything in a rack at high speeds, then have an even bigger pipe out to the rest of the network. The Pro Aggregation does this with it's SFP28 25Gbps ports. [pdf]
