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.

How to Maintain Management VLAN and Port Settings When Adopting Switches on Omada Network V6

Before Omada Controller V6, when adopting a switch on controller, the default configuration will be applied to the switch and override all the previous pre-configuration done in standalone mode. This could cause inconvenience while adopting switches to a network which management VLAN is not the default VLAN. If the default configuration, especially the default VLAN interface, overrides the pre-configuration done on the switch, it will be disconnected after adoption and hard to recover.

How to configure Management VLAN for Omada Devices (Omada Controller 5.15 or above)

The management VLAN is a VLAN created to separate the management network from the data network. By default, the management VLAN is the LAN network in a network centrally managed by Omada SDN Controller. You can change the management VLAN to improve network security. With a separated management VLAN, it is much harder for unauthorized users to modify the configurations or monitor the network.
