Managed layer 2 switches bring several benefits to aggregation networks. They offer efficient traffic management functionalities, including packet filtering, Quality of Service (QoS), and

Layer 2 Switches These are specialized switches that only operate at Layer 2, unlike multi-layer switches. Responsible for frame forwarding using

Layer 2 switches are essential for Local Area Networks (LANs), enabling smooth communication and efficient data traffic management. This guide breaks down the technical details, functions, and

An aggregation switch operates at Layer 2 or Layer 3 of the OSI model, depending on the configuration and topology of the network. The

This model allows the aggregation switches to easily accommodate thousands of devices passing through this layer while simplifying the design, maintenance, and operations. The following figure

Functional management: Unlike core switches, aggregation switches can be either Layer 2 or Layer 3 switches. When a Layer 2 switch is used as the aggregation switch, routing and

Unlike core switches, aggregation switches can be either Layer 2 or Layer 3 switches. When choosing a Layer 2 switch, the routing and management policies must be handled by the core

LACP Operation Two switches connected via multiple links will send LACPDU packets, identifying themselves and the port capabilities • They will then automatically build the logical aggregated links,

RouterOS Documentation This webpage contains the official RouterOS user manual. RouterOS is the operating system of MikroTik devices. Documentation applies for the latest stable

When the Layer 2 switch is selected as the distribution layer switch, the routing and management strategy must be completed by the core switch.

Layer 2 switches function at the data connection level of the OSI model where they are concerned mostly about forwarding frames using MAC addresses. They are designed for small to

Aggregation-layer submodule The aggregation-layer submodule plays a pivotal role in providing a highly reliable, scalable “middle layer” for bringing together the traffic from the access-layer submodule,

These aggregation switches typically operate at Layer 2 or Layer 3 of the OSI model, depending on the network topology and configuration

Redundancy and High Availability: Deploy redundant core switches, use dynamic routing protocols (such as OSPF, BGP) and link aggregation (LACP) to enhance network reliability.

OSI layer 2 (data link layer, e.g. Ethernet frame in LANs or multi-link PPP in WANs, Ethernet MAC address) aggregation typically occurs across switch ports, which can be either physical ports or
