This layer serves as the gateway to the campus core where other modules connect, including, for example, the extranet, WAN, and Internet edge. All links connecting the data center core are terminated at Layer 3 and typically use 10 Gig...See more on cisco Published: May 14, 2008Fortinet Documentation
Core layer | FortiSwitch 7.4.0 | Fortinet Document Library
The most appropriate FortiSwitch unit to form the core layer must have many 100 gigabit Ethernet ports to address the aggregation layer and distribute a few 100-GbE ports towards the core FortiGate
What Is a Core Switch?
Unlike access or distribution switches, a core switch is optimized for Layer 3 performance, modular scalability, and redundancy. In smaller networks, it may be combined with the distribution layer in a
L3 SWITCHES
The L3 switch is ideal for service provider edge aggregation, enterprise wiring closets, data center aggregation, and network core deployment. These switches bring a high level of security and traffic
Data Center Multi-Tier Model Design
In a large data center, a single pair of data center core switches typically interconnect multiple aggregation modules using 10 GigE Layer 3 interfaces. The recommended platform for the

What Is a Core Switch? Network Backbone Architecture Guide
To achieve backbone speeds, a core switch must operate at Layer 3 of the OSI model, bridging the gap between traditional MAC-based switching and IP-based routing.
General MS Best Practices
Use L3 interfaces only for data VLANs. This helps in separating management traffic from user data. In case of switch stacks, ensure that the management IP subnet does not overlap with the subnet of

This document describes the interoperation between H3C switches and third-party devices, as well as configuration of the associated parameters for interoperation.
FortiSwitchOS Switching Reference Architecture Guide
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.
What Is a Core Switch in Networking?
Unlike access switches, which connect directly to end-user devices, the core switch focuses on aggregating and routing traffic between other switches, minimizing latency and
