🛡️ DHCP Snooping: First Line of Defense in L2 Security
Rogue DHCP servers can poison your network, assign fake IPs, and redirect traffic. DHCP Snooping protects against this by:

• Validating DHCP messages via trusted ports
• Building a binding table for IP–MAC–VLAN mappings
• Blocking untrusted responses at the switch level

It’s simple, effective, and essential for campus & enterprise networks.
