Difference Between Layer 2 and Layer 3 Switches?

Layer 2 and Layer 3 switches are two of the most popular types of networking devices used in the modern day. While both have some similarities, there are also some major differences between them.

Layer 2 switches use a process called MAC address learning to forward data frames, while Layer 3 switch use IP routing to forward data packets. In terms of security, Layer 2 switches can provide basic security measures such as port security and VLANs, while Layer 3 switches can provide more advanced features such as ACLs and NATs.

Layer 2 switches are typically used in smaller networks or for connecting multiple subnets together, while Layer 3 switches are better suited for larger networks or for providing access to the Internet. Ultimately, which type of switch is best for you depends on your specific network requirements.
