What is a core switch?

A core switch is a high-capacity switch that serves as the primary backbone for a network. It is responsible for routing data between different subnets and controlling the flow of traffic within the network. Core switches are typically located at the center of a network and connect to distribution switches, access switches, and other network devices.

Some key features of a core switch include:

1. High performance: Core switches are designed to handle a large volume of traffic and provide fast data transmission speeds to ensure optimal network performance.

2. Redundancy: Core switches often have redundant power supplies, fans, and other components to minimize downtime and ensure high availability.

3. Scalability: Core switches are typically modular and can be expanded with additional ports and capabilities to accommodate the growing needs of a network.

4. Quality of Service (QoS) support: Core switches often support QoS features to prioritize certain types of traffic and ensure that critical applications have sufficient bandwidth and low latency.

5. Security: Core switches can be configured with advanced security features such as Access Control Lists (ACLs), Virtual LANs (VLANs), and encryption to protect the network from unauthorized access and cyber threats.

Overall, a core switch plays a critical role in ensuring the performance, scalability, and security of a network infrastructure. It serves as the central point that connects all network devices and facilitates the efficient transfer of data between them.
