What are Layer 3 Network Switches
Posted: Mon Nov 18, 2024 6:38 am
Layer 3 Network Switches are advanced network devices that combine the functionality of a switch and a router. While Layer 2 switches operate at the data link layer, handling the transfer of data packets within the same network, Layer 3 switches work at the network layer.
This allows them to perform routing functions and handle data traffic between different networks or subnets. Here’s a breakdown of what makes Layer 3 Network Switches unique:
Routing Capabilities:
Unlike Layer 2 switches, which rely solely on MAC addresses for packet forwarding, Layer 3 switches use IP addresses. This means they can make routing decisions and direct traffic between VLANs (Virtual Local Area Networks).
