Differences Between Layer 2 Switch and Layer 3 Switch

A Layer 2 switch operates at the data link layer (Layer 2) of the OSI model and makes forwarding decisions based on MAC addresses. It is primarily used for local network segmentation and reduces network congestion.

On the other hand, a Layer 3 switch operates at the network layer (Layer 3) of the OSI model and can make routing decisions based on IP addresses. It offers the functionality of both a switch and a router, providing faster packet processing in larger networks.

When to use each in a network environment:

  • Layer 2 switch: Ideal for small to medium-sized networks where VLAN segmentation and efficient data forwarding are needed without complex routing.
  • Layer 3 switch: Suitable for larger networks with multiple subnets that require routing between VLANs and faster packet routing capabilities.
