Core, Distribution, and Access Layer Explained with Examples
A multinational bank might have core switches in regional data centers, distribution switches in each country office, and access switches on every floor of their buildings.
Access layer | FortiSwitch 7.6.0 | Fortinet Document Library
Using this design, you can go up to eight switches and never need more than 4x10-GbE ports per switch to interconnect other access-layer switches or the aggregation layer.
Data Center Network Switch Design
By following these design and deployment strategies, you can achieve a high-performance, highly available, and secure network architecture that meets the needs of your
LAN Topologies
The access switches provide Layer 2 services to connected endpoints and connect to core switches providing both Layer 2 and Layer 3 services. The two-tier design is well suited for
What does a layer 3 access design look like?
I often hear it''s advantageous to utilize layer 3 at the access layer devices to avoid having broadcasts spanning the network and not having to deal with huge STP topologies. But what exactly does this

Comprehensive guide to Core, Distribution, and Access Switches. Roles in the network and important parameters explained.
Data Center Access Layer Design
The loop-free U topology design provides a Layer 2 access solution with active uplinks and redundancy via an inter-switch link between the access layer switches.
Access, Distribution, and Core Layers Explained
This tutorial provides an overview of the access, distribution, and core layers and explains two-tier and three-tier campus LAN designs.
Choose access layer switch for the access layer network
In each layer, the enterprise switches are categorized, among which the access switch is a key part in which local end-users are allowed into the network. This article will introduce what the
