suresh Understanding the Difference Between Layer 2 and Layer 3 Switches in a Networking Environment
In a networking environment, the difference between Layer 2 and Layer 3 switches lies in their respective functions and capabilities. Layer 2 switches operate at the data link layer of the OSI model, primarily focusing on MAC addresses for forwarding frames within a local area network (LAN). On the other hand, Layer 3 switches function at the network layer of the OSI model, using IP addresses to route traffic between different subnets or networks.
Key Differences:
1. Addressing: Layer 2 switches use MAC addresses for forwarding frames, while Layer 3 switches use IP addresses for routing traffic.
2. Scope: Layer 2 switches work within the same LAN, whereas Layer 3 switches can operate across multiple networks or subnets.
3. Functionality: Layer 2 switches are more focused on local data transmission and MAC address learning, while Layer 3 switches offer routing capabilities for interconnecting networks.
