Understanding the Key Differences Between Layer 2 and Layer 3 Switches

Layer 2 switches operate at the Data Link layer of the OSI model and use MAC addresses to forward the data packets within the same network segment. They are capable of forwarding data based on the MAC address of the devices connected to them.

On the other hand, Layer 3 switches operate at the Network layer of the OSI model and can make routing decisions based on IP addresses. They are more intelligent and can route data between different networks by analyzing the IP addresses in the packets.

Essentially, the main difference between a Layer 2 and a Layer 3 switch is the level at which they operate within the OSI model and the type of addresses they use for forwarding data.

Overall, while Layer 2 switches are more simplistic and operate at the MAC address level, Layer 3 switches are more advanced and can perform routing functions based on IP addresses.
