Configuration Guidelines
When configuring DHCP snooping, follow these guidelines:
• DHCP snooping is not active until you enable the feature on at least one VLAN, and enable DHCP snooping globally on the switch.
• Before globally enabling DHCP snooping on the switch, make sure that the device acting as the DHCP server is configured and enabled.
• If a Layer 2 LAN port is connected to a DHCP server, configure the port as trusted by entering the ip dhcp snooping trust interface configuration command.
• If a Layer 2 LAN port is connected to a DHCP client, configure the port as un-trusted by entering the no ip dhcp snooping trust interface configuration command.
