To complete DHCP Snooping configuration, follow these steps:
1) Enable DHCP Snooping on VLAN.
2) Configure DHCP Snooping on the specified port.
3) (Optional) Configure Option 82 on the specified port.
Tips:
The switch can dynamically bind the entries via DHCP Snooping after step 1 and step
2 are completed. By default, the binding entries are applied to ARP Detection.
Configuration Guidelines
DHCP Snooping and DHCP Relay cannot be used at the same time on the switch. When
both of these features are enabled, only DHCP Relay will work.
