How can we do MAC address binding in Layer 2 (L2) and Layer 3 (L3) switches?
Is it necessary to apply no IP route cache on virtual local area networks (VLAN) interfaces in an L3 switch and why? What are the advantages or disadvantages?

Why do we use Layer 3 (L3) switches, and how are they different from Layer 2 (L2) switches?
