Which capability differentiates a Layer 3 switch from a Layer 2 switch?
Support for MAC address filtering
Possession of multiple Ethernet ports
Capability to route traffic between different IP subnets
Ability to perform VLAN segmentation
Layer 3 switches can route traffic between different IP subnets, functioning similarly to a router. This allows them to perform IP routing and make forwarding decisions based on IP addresses. Layer 2 switches do not have this capability; they forward frames based on MAC addresses within the same network segment. VLAN segmentation and MAC address filtering are features available on both Layer 2 and Layer 3 switches. Having multiple Ethernet ports is common to both devices and does not distinguish them.
