What is DHCP Snooping and DAI and How to Configure Them on Omada Switches When Adopted on Omada Controller
DHCP Snooping and Dynamic ARP Inspection (DAI) are essential Layer 2 security features designed to enhance network protection. Both features are parts of IP-MAC-Port Binding (IMPB) on Omada switches.
For DHCP Snooping, the feature dynamically builds and maintains an IP-MAC-Port binding table by snooping legitimate DHCP transactions. This table records valid associations between a client's IP address, MAC address, connected port, VLAN, and lease duration.
